Each combines, on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, the 56F8346 and 56F8146 are well-suited for many applications. The devices include many peripherals that are especially useful for motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control (56F8346 only), engine management, noise suppression, remote utility metering, industrial control for power, lighting, and automation applications. The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and optimized instruction set allow straightforward generation of efficient, compact DSP and control code. The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized control applications. The 56F8346 and 56F8146 support program execution from either internal or external memories. Two data operands can be accessed from the on-chip data RAM per instruction cycle. These devices also provide two external dedicated interrupt lines and up to 62 General Purpose Input/Output (GPIO) lines, depending on peripheral configuration. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 9 1.2.1 56F8346 Features The 56F8346 controller includes 128KB of Program Flash and 8KB of Data Flash (each programmable through the JTAG port) with 4KB of Program RAM and 8KB of Data RAM. It also supports program execution from external memory. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased. A key application-specific feature of the 56F8346 is the inclusion of two Pulse Width Modulator (PWM) modules. These modules each incorporate three complementary, individually programmable PWM signal output pairs (each module is also capable of supporting six independent PWM functions, for a total of 12 PWM outputs) to enhance motor control functionality. Complementary operation permits programmable dead time insertion, distortion correction via current sensing by software, and separate top and bottom output polarity control. The up-counter value is programmable to support a continuously variable PWM frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance Motors); and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting with sufficient output drive capability to directly drive standard optoisolators. A “smoke-inhibit”, write-once protection feature for key parameters is also included. A patented PWM waveform distortion correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit integral reload rates to be programmable from 1 to 16. The PWM modules provide reference outputs to synchronize the Analog-to-Digital Converters through two channels of Quad Timer C. The 56F8346 incorporates two Quadrature Decoders capable of capturing all four transitions on the two-phase inputs, permitting generation of a number proportional to actual position. Speed computation capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the Quadrature Decoder can be programmed with a time-out value to alert when no shaft motion is detected. Each input is filtered to ensure only true transitions are recorded. This controller also provides a full set of standard programmable peripherals that include two Serial Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal interrupt controller are a part of the 56F8346. 1.2.2 56F8146 Features The 56F8146 hybrid controller includes 128KB of Program Flash, programmable through the JTAG port, with 8KB of Data RAM. It also supports program execution from external memory. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of field-programmable software routines that can be used to program the main Program Flash memory area, which can be independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot Flash page erase size is 512 bytes and the Boot Flash memory can also be either bulk or page erased. 56F8346 Technical Data, Rev. 15 10 Freescale Semiconductor Preliminary Award-Winning Development Environment A key application-specific feature of the 56F8146 is the inclusion of one Pulse Width Modulator (PWM) module.

An internal interrupt controller is also a part of the 56F8146. 1.3 Award-Winning Development Environment Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use component-based software application creation with an expert knowledge system. The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation, compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs create a complete, scalable tools solution for easy, fast, and efficient development. 1.4 Architecture Block Diagram Note: Features in italics are NOT available in the 56F8146 device and are shaded in the following figures. The 56F8346/56F8146 architecture is shown in Figure 1-1 and Figure 1-2. Figure 1-1 illustrates how the 56800E system buses communicate with internal memories, the external memory interface and the IPBus Bridge. Table 1-2 lists the internal buses in the 56800E architecture and provides a brief description of their function. Figure 1-2 shows the peripherals and control blocks connected to the IPBus Bridge. The figures do not show the on-board regulator and power and ground signals. They also do not show the multiplexing between peripherals or the dedicated GPIOs. Please see Part 2, Signal/Connection Descriptions, to see which signals are multiplexed with those of other peripherals. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 11 Also shown in Figure 1-2 are connections between the PWM, Timer C and ADC blocks. These connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The Timer C channel indicated can generate periodic start (SYNC) signals to the ADC to start its conversions. In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer C input channel as indicated. The timer can then be used to introduce a controllable delay before generating its output signal. The timer output then triggers the ADC. To fully understand this interaction, please see the 56F8300 Peripheral User Manual for clarification on the operation of all three of these peripherals. 56F8346 Technical Data, Rev. 15 12 Freescale Semiconductor Preliminary Architecture Block Diagram 5 JTAG / EOnCE Boot Flash pdb_m[15:0] pab[20:0] Program Flash Program RAM cdbw[13:0] 56800E EMI CHIP TAP Controller 17 16 6 Address Data Control TAP Linking Module xab1[23:0] xab2[23:0] Data RAM External JTAG Port Data Flash cdbr_m[31:0] xdb2_m[15:0] IPBus Bridge To Flash Control Logic NOT available on the 56F8146 device.

Any alternate functionality must be programmed. Note: Signals in italics are NOT available in the 56F8146 device. If the “State During Reset” lists more than one state for a pin, the first state is the actual reset state. Other states show the reset condition of the alternate function, which you get if the alternate pin function is selected without changing the configuration of the alternate peripheral. For example, the A8/GPIOA0 pin shows that it is tri-stated during reset. If the GPIOA_PER is changed to select the GPIO function of the pin, it will become an input if no other registers are changed.

RESET 86 Schmitt Input Input, pull-up enabled Reset — This input is a direct hardware reset on the processor. When RESET is asserted low, the device is initialized and placed in the reset state. A Schmitt trigger input is used for noise immunity. When the RESET pin is deasserted, the initial chip operating mode is latched from the EXTBOOT pin. The internal reset signal will be deasserted synchronous with the internal clocks after a fixed number of internal clocks. To ensure complete hardware reset, RESET and TRST should be asserted together. The only exception occurs in a debugging environment when a hardware device reset is required and the JTAG/EOnCE module must not be reset. In this case, assert RESET but do not assert TRST. Note: The internal Power-On Reset will assert on initial power-up. To deactivate the internal pull-up resistor, set the RESET bit in the SIM_PUDR register. See Part 6.5.6 for details.

This function is also affected by EXTBOOT and the Flash security mode. For details, see Table 4-4. If a 20-bit address bus is not desired, then this pin is tied to ground. Note: When this pin is tied low, the customer boot software should disable the internal pull-up resistor by setting the EMI_MODE bit of the SIM_PUDR; see Part 6.5.6. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 39 Part 3 On-Chip Clock Synthesis (OCCS) 3.1 Introduction Refer to the OCCS chapter of the 56F8300 Peripheral User Manual for a full description of the OCCS.

To generate a reference frequency using the internal oscillator, a reference crystal or ceramic resonator, must be connected between the EXTAL and XTAL pins. 3.2.1 Crystal Oscillator The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency range specified for the external crystal in Table 10-15. A recommended crystal oscillator circuit is shown in Figure 3-2. Follow the crystal supplier’s recommendations when selecting a crystal, since crystal parameters determine the component values required to provide maximum stability and reliable start-up. 56F8346 Technical Data, Rev. 15 40 Freescale Semiconductor Preliminary External Clock Operation The crystal and associated components should be mounted as near as possible to the EXTAL and XTAL pins to minimize output distortion and start-up stabilization time. Crystal Frequency = 4 - 8MHz (optimized for 8MHz) EXTAL XTAL Rz CLKMODE = 0 EXTAL XTAL Rz Sample External Crystal Parameters: Rz = 750 KΩ Note: If the operating temperature range is limited to below 85oC (105oC junction), then Rz = 10 Meg Ω CL1 CL2 Figure 3-2 Connecting to a Crystal Oscillator Note: The OCCS_COHL bit must be set to 1 when a crystal oscillator is used. The reset condition on the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL) register, discussed in the 56F8300 Peripheral User Manual. 3.2.2 Ceramic Resonator (Default) It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system design can tolerate the reduced signal integrity. A typical ceramic resonator circuit is shown in Figure 3-3. Refer to the supplier’s recommendations when selecting a ceramic resonator and associated components. The resonator and components should be mounted as near as possible to the EXTAL and XTAL pins. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 41 Resonator Frequency = 4 - 8MHz (optimized for 8MHz) 2 Terminal EXTAL Rz XTAL 3 Terminal EXTAL Rz XTAL Sample External Ceramic Resonator Parameters: Rz = 750 KΩ CL1 CL2 C1 C2 CLKMODE = 0 Figure 3-3 Connecting a Ceramic Resonator Note: The OCCS_COHL bit must be set to 0 when a ceramic resonator is used. The reset condition on the OCCS_COHL bit is 0. Please see the COHL bit in the Oscillator Control (OSCTL) register, discussed in the 56F8300 Peripheral User Manual. 3.2.3 External Clock Source The recommended method of connecting an external clock is illustrated in Figure 3-4. The external clock source is connected to XTAL and the EXTAL pin is grounded. Set OCCS_COHL bit high when using an external clock source as well. XTAL External Clock EXTAL VSS Note: When using an external clocking source with this configuration, the input “CLKMODE” should be high and the COHL bit in the OSCTL register should be set to 1. Figure 3-4 Connecting an External Clock Register 3.3 Registers When referring to the register definitions for the OCCS in the 56F8300 Peripheral User Manual, use the register definitions without the internal Relaxation Oscillator, since the 56F8346/56F8146 devices do NOT contain this oscillator. Part 4 Memory Map 4.1 Introduction The 56F8346 and 56F8146 devices are 16-bit motor-control chips based on the 56800E core. These parts use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip RAM and Flash memories are used in both spaces. 56F8346 Technical Data, Rev. 15 42 Freescale Semiconductor Preliminary Introduction This section provides memory maps for: • • Program Address Space, including the Interrupt Vector Table Data Address Space, including the EOnCE Memory and Peripheral Memory Maps On-chip memory sizes for each device are summarized in Table 4-1. Flash memories’ restrictions are identified in the “Use Restrictions” column of Table 4-1. Note: Data Flash and Program RAM are NOT available on the 56F8146 device.

At reset, these bits are set as indicated in Table 4-2. Table 4-4 shows the memory map configurations that are possible at reset. After reset, the OMR MA bit can be changed and will have an effect on the P-space memory map, as shown in Table 4-3. Changing the OMR MB bit will have no effect. Table 4-2 OMR MB/MA Value at Reset OMR MB = Flash Secured State1, 2 0 0 1 1 OMR MA = EXTBOOT Pin 0 1 0 1 Chip Operating Mode Mode 0 – Internal Boot; EMI is configured to use 16 address lines; Flash Memory is secured; external P-space is not allowed; the EOnCE is disabled Not valid; cannot boot externally if the Flash is secured and will actually configure to 00 state Mode 0 – Internal Boot; EMI is configured to use 16 address lines Mode 1 – External Boot; Flash Memory is not secured; EMI configuration is determined by the state of the EMI_MODE pin 1. This bit is only configured at reset. If the Flash secured state changes, this will not be reflected in MB until the next reset. 2. Changing MB in software will not affect Flash memory security. Table 4-3 Changing OMR MA Value During Normal Operation OMR MA 0 1 Chip Operating Mode Use internal P-space memory map configuration Use external P-space memory map configuration – If MB = 0 at reset, changing this bit has no effect. The device’s external memory interface (EMI) can operate much like the 56F80x family’s EMI, or it can be operated in a mode similar to that used on other products in the 56800E family. Initially, CS0 and CS1 are configured as PS and DS, in a mode compatible with earlier 56800 devices. Eighteen address lines are required to shadow the first 192K of internal program space when booting externally for development purposes. Therefore, the entire complement of on-chip memory cannot be accessed using a 16-bit 56800-compatible address bus. To address this situation, the EMI_MODE pin can be used to configure four GPIO pins as Address[19:16] upon reset (only one of these pins [A16] is usable 56F8346 Technical Data, Rev. 15 44 Freescale Semiconductor Preliminary Interrupt Vector Table in the 56F8346/56F8146). The EMI_MODE pin also affects the reset vector address, as provided in Table 4-4. Additional pins must be configured as address or chip select signals to access addresses at P:$10 0000 and above. Note: Program RAM is NOT available on the 56F8146 device.

If Flash Security Mode is enabled, EXTBOOT Mode 1 cannot be used. See Security Features, Part 7. 2. This mode provides maximum compatibility with 56F80x parts while operating externally. 3. “EMI_MODE =0” when EMI_MODE pin is tied to ground at boot up. 4. “EMI_MODE =1” when EMI_MODE pin is tied to VDD at boot up. 5. Not accessible in reset configuration, since the address is above P:$00 FFFF. The higher bit address/GPIO (and/or chip selects) pins must be reconfigured before this external memory is accessible. 6. Booting from this external address allows prototyping of the internal Boot Flash. 7. The internal Program Flash is relocated in this mode making it accessible. 4.3 Interrupt Vector Table Table 4-5 provides the reset and interrupt priority structure, including on-chip peripherals. The table is organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The priority of an interrupt can be assigned to different levels, as indicated, allowing some control over 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 45 interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority level, the lowest vector number has the highest priority. The location of the vector table is determined by the Vector Base Address (VBA) register. Please see Part 5.6.12 for the reset value of the VBA. In some configurations, the reset address and COP reset address will correspond to vector 0 and 1 of the interrupt vector table.

Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced from the vector table, providing only 19 bits of address. 2. If the VBA is set to 0200 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are the chip reset addresses; therefore, these locations are not interrupt vectors. 2. 4.4 Data Map Note: Data Flash is NOT available on the 56F8146 device.

The Data RAM is organized as a 2K x 32-bit memory to allow single-cycle long-word operations. 4.5 Flash Memory Map Figure 4-1 illustrates the Flash Memory (FM) map on the system bus. The Flash Memory is divided into three functional blocks. The Program and boot memories reside on the 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 49 Program Memory buses. They are controlled by one set of banked registers. Data Memory Flash resides on the Data Memory buses and is controlled separately by own set of banked registers. The top nine words of the Program Memory Flash are treated as special memory locations. The content of these words is used to control the operation of the Flash Controller. Because these words are part of the Flash Memory content, their state is maintained during power-down and reset. During chip initialization, the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash Memory chapter of the 56F8300 Peripheral User Manual. These configuration parameters are located between $00_FFF7 and $00_FFFF.

These locations may be accessed with the same addressing modes used for ordinary Data memory, except all peripheral registers should be read/written using word accesses only. Table 4-9 summarizes base addresses for the set of peripherals on the 56F8346 and 56F8146 devices. Peripherals are listed in order of the base address. The following tables list all of the peripheral registers required to control or access the peripherals. Note: Features in italics are NOT available on the 56F8146 device.

4.8 Factory Programmed Memory The Boot Flash memory block is programmed during manufacturing with a default Serial Bootloader program. The Serial Bootloader application can be used to load a user application into the Program and Data Flash (NOT available in the 56F8146 device) memories of the device. The 56F83xx SCI/CAN Bootloader User Manual (MC56F83xxBLUM) provides detailed information on this firmware. An application note, Production Flash Programming (AN1973), details how the Serial Bootloader program can be used to perform production Flash programming of the on-board Flash memories as well as other potential methods. Like all the Flash memory blocks, the Boot Flash can be erased and programmed by the user. The Serial Bootloader application is programmed as an aid to the end user, but is not required to be used or maintained in the Boot Flash memory. Part 5 Interrupt Controller (ITCN) 5.1 Introduction The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to signal to the 56800E core when an interrupt of sufficient priority exists, and to what address to jump in order to service this interrupt. 5.2 Features The ITCN module design includes these distinctive features: • • • • Programmable priority levels for each IRQ Two programmable Fast Interrupts Notification to SIM module to restart clocks out of Wait and Stop modes Drives initial address on the address bus after reset For further information, see Table 4-5, Interrupt Vector Table Contents. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 79 5.3 Functional Description The Interrupt Controller is a slave on the IPBus. It contains registers allowing each of the 82 interrupt sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. Next, all of the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the active interrupt requests for that level. Within a given priority level, zero is the highest priority, while number 81 is the lowest. 5.3.1 Normal Interrupt Handling Once the ITCN has determined that an interrupt is to be serviced and which interrupt has the highest priority, an interrupt vector address is generated. Normal interrupt handling concatenates the VBA and the vector number to determine the vector address. In this way, an offset is generated into the vector table for each interrupt. 5.3.2 Interrupt Nesting Interrupt exceptions may be nested to allow an IRQ of higher priority than the current exception to be serviced. The following tables define the nesting requirements for each priority level.

See IPIC field definition in Part 5.6.30.2. 5.3.3 Fast Interrupt Handling Fast interrupts are described in the DSP56800E Reference Manual. The interrupt controller recognizes fast interrupts before the core does. A fast interrupt is defined (to the ITCN) by: 56F8346 Technical Data, Rev. 15 80 Freescale Semiconductor Preliminary Block Diagram 1. Setting the priority of the interrupt as level 2, with the appropriate field in the IPR registers 2. Setting the FIMn register to the appropriate vector number 3. Setting the FIVALn and FIVAHn registers with the address of the code for the fast interrupt When an interrupt occurs, its vector number is compared with the FIM0 and FIM1 register values. If a match occurs, and it is a level 2 interrupt, the ITCN handles it as a fast interrupt. The ITCN takes the vector address from the appropriate FIVALn and FIVAHn registers, instead of generating an address that is an offset from the VBA. The core then fetches the instruction from the indicated vector adddress and if it is not a JSR, the core starts its fast interrupt handling. 5.4 Block Diagram Priority Level any0 Level 0 82 -> 7 Priority Encoder 7 INT1 2 -> 4 Decode INT VAB CONTROL IPIC any3 Level 3 Priority Level 82 -> 7 Priority Encoder IACK 7 SR[9:8] PIC_EN INT82 2 -> 4 Decode Figure 5-1 Interrupt Controller Block Diagram 5.5 Operating Modes The ITCN module design contains two major modes of operation: • Functional Mode The ITCN is in this mode by default. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 81 • Wait and Stop Modes During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN will signal a pending IRQ to the System Integration Module (SIM) to restart the clocks and service the IRQ. An IRQ can only wake up the core if the IRQ is enabled prior to entering the Wait or Stop mode. Also, the IRQA and IRQB signals automatically become low-level sensitive in these modes even if the control register bits are set to make them falling-edge sensitive. This is because there is no clock available to detect the falling edge. A peripheral which requires a clock to generate interrupts will not be able to generate interrupts during Stop mode. The FlexCAN module can wake the device from Stop mode, and a reset will do just that, or IRQA and IRQB can wake it up. 5.6 Register Descriptions A register address is the sum of a base address and an address offset. The base address is defined at the system level and the address offset is defined at the module level. The ITCN peripheral has 24 registers.

Part 6 System Integration Module (SIM) 6.1 Overview The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls distribution of resets and clocks and provides a number of control features. The system integration module is responsible for the following functions: • • • • • • Reset sequencing Clock generation & distribution Stop/Wait control Pull-up enables for selected peripherals System status registers Registers for software access to the JTAG ID of the chip 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 109 • Enforcing Flash security These are discussed in more detail in the sections that follow. 6.2 Features The SIM has the following features: • • • Flash security feature prevents unauthorized access to code/data contained in on-chip Flash memory Power-saving clock gating for peripheral Three power modes (Run, Wait, Stop) to control power utilization — Stop mode shuts down the 56800E core, system clock, peripheral clock, and PLL operation — Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart); must be explicitly done — Wait mode shuts down the 56800E core and unnecessary system clock operation — Run mode supports full part operation • • • • • • • Controls to enable/disable the 56800E core WAIT and STOP instructions Calculates base delay for reset extension based upon POR or RESET operations. Reset delay will be either 3 x 32 clocks (phased release of reset) for reset, except for POR, which is 221 clock cycles.

These are: • Reset Mode, which has two submodes: — POR and RESET operation The 56800E core and all peripherals are reset. This occurs when the internal POR is asserted or the RESET pin is asserted. — COP reset and software reset operation The 56800E core and all peripherals are reset. The MA bit within the OMR is not changed. This allows the software to determine the boot mode (internal or external boot) to be used on the next reset. • • Run Mode This is the primary mode of operation for this device. In this mode, the 56800E controls chip operation. Debug Mode The 56800E is controlled via JTAG/EOnCE when in debug mode. All peripherals, except the COP and PWMs, continue to run. COP is disabled and PWM outputs are optionally switched off to disable any motor from being driven; see the PWM chapter in the 56F8300 Peripheral User Manual for details. Wait Mode In Wait mode, the core clock and memory clocks are disabled. Optionally, the COP can be stopped. Similarly, it is an option to switch off PWM outputs to disable any motor from being driven. All other peripherals continue to run. Stop Mode When in Stop mode, the 56800E core, memory, and most peripheral clocks are shut down. Optionally, the COP and CAN can be stopped. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. The CAN (along with any non-gated interrupt) is capable of waking the chip up from Stop mode, but is not fully functional in Stop mode. • • 6.4 Operating Mode Register Bit Type RESET 15 NL R/W 0 0 0 0 0 0 0 14 13 12 11 10 9 8 CM R/W 0 7 XP R/W 0 6 SD R/W 0 5 R R/W 0 4 SA R/W 0 3 EX R/W 0 2 0 1 MB R/W 0 MA R/W X 0 X Figure 6-1 OMR The reset state for MB and MA will depend on the Flash secured state.

During reset, this bit, coupled with the EXTBOOT signal, is used to initialize address bits [19:16] either as GPIO or as address. These settings can be explicitly overwritten using the appropriate GPIO peripheral enable register at any time after reset. In addition, this pin can be used as a general purpose input pin after reset. • • 0 = External address bits [19:16] are initially programmed as GPIO 1 = When booted with EXTBOOT = 1, A[19:16] are initially programmed as address.

A reset (other than POR) will only set bits in the register; bits are not cleared. Only software should clear this register.

It is read as 0 and cannot be modified by writing. When 1, this bit indicates that the previous reset occurred as a result of a software reset (write to SW RST bit in the SIM_CONTROL register). This bit will be cleared by any hardware reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit will clear it. 6.5.2.3 COP Reset (COPR)—Bit 4 When 1, the COPR bit indicates the Computer Operating Properly (COP) timer-generated reset has occurred. This bit will be cleared by a Power-On Reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit will clear it. 6.5.2.4 External Reset (EXTR)—Bit 3 If 1, the EXTR bit indicates an external system reset has occurred. This bit will be cleared by a Power-On Reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit position will clear it. Basically, when the EXTR bit is 1, the previous system reset was caused by the external RESET pin being asserted low. 56F8346 Technical Data, Rev. 15 114 Freescale Semiconductor Preliminary Register Descriptions 6.5.2.5 Power-On Reset (POR)—Bit 2 When 1, the POR bit indicates a Power-On Reset occurred some time in the past. This bit can be cleared only by software or by another type of reset. Writing a 0 to this bit will set the bit, while writing a 1 to the bit position will clear the bit. In summary, if the bit is 1, the previous system reset was due to a Power-On Reset. 6.5.2.6 Reserved—Bits 1–0 This bit field is reserved or not implemented.

Pins which can operate as GPIO can have these resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the appropriate bit in this register. Disabling pull-ups is done on a peripheral-by-peripheral basis (for pins not muxed with GPIO). Each bit in the register (see Figure 6-8) corresponds to a functional group of pins. See Table 2-2 to identify which pins can deactivate the internal pull-up resistor.

The default value is SYS_CLK. All other clocks primarily muxed out are for test purposes only, and are subject to significant unspecified latencies at high frequencies. The upper four bits of the GPIOB register can function as GPIO, A[23:20], or as additional clock output signals. GPIO has priority and is enabled/disabled via the GPIOB_PER. If GPIOB[7:4] are programmed to operate as peripheral outputs, then the choice between A[23:20] and additional clock outputs is done here in the CLKOSR. The default state is for the peripheral function of GPIOB[7:4] to be programmed as A[23:20]. This can be changed by altering A[23:20], as shown in Figure 6-9.

The default peripheral is Quad Decoder 1 and Quad Timer B (NOT available in the 56F8146 device); these peripherals work together. The four I/O pins associated with GPIOC can function as GPIO, Quad Decoder 1/Quad Timer B, or as SPI 1 signals. GPIO is not the default and is enabled/disabled via the GPIOC_PER, as shown in Figure 6-10 and Table 6-2. When GPIOC[3:0] are programmed to operate as peripheral I/O, then the choice between decoder/timer and SPI inputs/outputs is made in the SIM_GPS register and in conjunction with the Quad Timer Status and Control Registers (SCR). The default state is for the peripheral function of GPIOC[3:0] to be programmed as decoder functions. This can be changed by altering the appropriate controls in the indicated registers.

The I/O short address mode allows the instruction to specify the lower six bits of address; the upper address bits are not directly controllable. This register set allows limited control of the full address, as shown in Figure 6-13. Note: If this register is set to something other than the top of memory (EOnCE register space) and the EX bit in the OMR is set to 1, the JTAG port cannot access the on-chip EOnCE registers, and debug functions will be affected. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 123 “Hard Coded” Address Portion 6 Bits from I/O Short Address Mode Instruction Instruction Portion 16 Bits from SIM_ISALL Register 2 bits from SIM_ISALH Register Full 24-Bit for Short I/O Address Figure 6-13 I/O Short Address Determination With this register set, an interrupt driver can set the SIM_ISALL register pair to point to its peripheral registers and then use the I/O Short addressing mode to reference them.

The maximum master clock frequency is 120MHz. Peripheral and system clocks are generated at half the master clock frequency and therefore at a maximum 60MHz. The SIM provides power modes (Stop, Wait) and clock enables (SIM_PCE register, CLK_DIS, ONCE_EBL) to control which clocks are in operation. The OCCS, power modes, and clock enables provide a flexible means to manage power consumption. Power utilization can be minimized in several ways. In the OCCS, crystal oscillator, and PLL may be shut down when not in use. When the PLL is in use, its prescaler and postscaler can be used to limit PLL and master clock frequency. Power modes permit system and/or peripheral clocks to be disabled when unused. Clock enables provide the means to disable individual clocks. Some peripherals provide further controls to disable unused subfunctions. Refer to the Part 3 On-Chip Clock Synthesis (OCCS), and the 56F8300 Peripheral User Manual for further details. 6.7 Power-Down Modes Overview The 56F8346/56F8146 devices operate in one of three power-down modes, as shown in Table 6-3. Table 6-3 Clock Operation in Power-Down Modes Mode Run Wait Core Clocks Active Core and memory clocks disabled Peripheral Clocks Active Active Description Device is fully functional Peripherals are active and can product interrupts if they have not been masked off. Interrupts will cause the core to come out of its suspended state and resume normal operation. Typically used for power-conscious applications. The only possible recoveries from Stop mode are: 1. CAN traffic (1st message will be lost) 2. Non-clocked interrupts 3. COP reset 4. External reset 5. Power-on reset Stop System clocks continue to be generated in the SIM, but most are gated prior to reaching memory, core and peripherals. All peripherals, except the COP/watchdog timer, run off the IPBus clock frequency, which is the same as the main processor frequency in this architecture. The maximum frequency of operation is SYS_CLK = 60MHz. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 125 6.8 Stop and Wait Mode Disable Function Permanent Disable D Q D-FLOP C 56800E Reprogrammable Disable STOP_DIS D Q D-FLOP Clock Select Reset C R Note: Wait disable circuit is similar Figure 6-16 Internal Stop Disable Circuit The 56800E core contains both STOP and WAIT instructions. Both put the CPU to sleep. For lowest power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. When the PLL is shut down, the 56800E system clock must be set equal to the prescaler output. Some applications require the 56800E STOP and WAIT instructions be disabled. To disable those instructions, write to the SIM control register (SIM_CONTROL), described in Part 6.5.1. This procedure can be on either a permanent or temporary basis. Permanently assigned applications last only until their next reset. 6.9 Resets The SIM supports four sources of reset. The two asynchronous sources are the external RESET pin and the Power-On Reset (POR). The two synchronous sources are the software reset, which is generated within the SIM itself by writing to the SIM_CONTROL register, and the COP reset. Reset begins with the assertion of any of the reset sources. Release of reset to various blocks is sequenced to permit proper operation of the device. A POR reset is first extended for 221 clock cycles to permit stabilization of the clock source, followed by a 32 clock window in which SIM clocking is initiated. It is then followed by a 32 clock window in which peripherals are released to implement Flash security, and, finally, followed by a 32 clock window in which the core is initialized. After completion of the described reset sequence, application code will begin execution. Resets may be asserted asynchronously, but they are always released internally on a rising edge of the system clock. 56F8346 Technical Data, Rev. 15 126 Freescale Semiconductor Preliminary Operation with Security Enabled Part 7 Security Features The 56F8346/56F8146 offer security features intended to prevent unauthorized users from reading the contents of the Flash Memory (FM) array. The Flash security consists of several hardware interlocks that block the means by which an unauthorized user could gain access to the Flash array. However, part of the security must lie with the user’s code. An extreme example would be user’s code that dumps the contents of the internal program, as this code would defeat the purpose of security. At the same time, the user may also wish to put a “backdoor” in his program. As an example, the user downloads a security key through the SCI, allowing access to a programming routine that updates parameters stored in another section of the Flash. 7.1 Operation with Security Enabled Once the user has programmed the Flash with his application code, the device can be secured by programming the security bytes located in the FM configuration field, which occupies a portion of the FM array. These non-volatile bytes will keep the part secured through reset and through power-down of the device. Only two bytes within this field are used to enable or disable security. Refer to the Flash Memory section in the 56F8300 Peripheral User Manual for the state of the security bytes and the resulting state of security. When Flash security mode is enabled in accordance with the method described in the Flash Memory module specification, the device will disable external P-space accesses restricting code execution to internal memory, disable EXTBOOT = 1 mode, and disable the core EOnCE debug capabilities. Normal program execution is otherwise unaffected. 7.2 Flash Access Blocking Mechanisms The 56F8346/56F8146 have several operating functional and test modes. Effective Flash security must address operating mode selection and anticipate modes in which the on-chip Flash can be compromised and read without explicit user permission. Methods to block these are outlined in the next subsections. 7.2.1 • • • Forced Operating Mode Selection Internal Boot Mode External Boot Mode Secure Mode At boot time, the SIM determines in which functional modes the device will operate. These are: When Flash security is enabled as described in the Flash Memory module specification, the device will boot in internal boot mode, disable all access to external P-space, and start executing code from the Boot Flash at address 0x02_0000. This security affords protection only to applications in which the device operates in internal Flash security 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 127 mode. Therefore, the security feature cannot be used unless all executing code resides on-chip. When security is enabled, any attempt to override the default internal operating mode by asserting the EXTBOOT pin in conjunction with reset will be ignored. 7.2.2 Disabling EOnCE Access On-chip Flash can be read by issuing commands across the EOnCE port, which is the debug interface for the 56800E core. The TRST, TCLK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the EOnCE port functionality is mapped. When the device boots, the chip-level JTAG TAP (Test Access Port) is active and provides the chip’s boundary scan capability and access to the ID register. Proper implementation of Flash security requires that no access to the EOnCE port is provided when security is enabled. The 56800E core has an input which disables reading of internal memory via the JTAG/EOnCE. The FM sets this input at reset to a value determined by the contents of the FM security bytes. 7.2.3 Flash Lockout Recovery If a user inadvertently enables Flash security on the device, a built-in lockout recovery mechanism can be used to reenable access to the device. This mechanism completely reases all on-chip Flash, thus disabling Flash security. Access to this recovery mechanism is built into CodeWarrior via an instruction in memory configuration (.cfg) files. Add, or uncomment the following configuration command: unlock_flash_on_connect 1 For more information, please see CodeWarrior MC56F83xx/DSP5685x Family Targeting Manual. The LOCKOUT_RECOVERY instruction has an associated 7-bit Data Register (DR) that is used to control the clock divider circuit within the FM module. This divider, FM_CLKDIV[6:0], is used to control the period of the clock used for timed events in the FM erase algorithm. This register must be set with appropriate values before the lockout sequence can begin. Refer to the JTAG section of the 56F8300 Peripheral User Manual for more details on setting this register value. The value of the JTAG FM_CLKDIV[6:0] will replace the value of the FM register FMCLKD that divides down the system clock for timed events, as illustrated in Figure 7-1. FM_CLKDIV[6] will map to the PRDIV8 bit, and FM_CLKDIV[5:0] will map to the DIV[5:0] bits. The combination of PRDIV8 and DIV must divide the FM input clock down to a frequency of 150kHz-200kHz. The “Writing the FMCLKD Register” section in the Flash Memory chapter of the 56F8300 Peripheral User Manual gives specific equations for calculating the correct values. 56F8346 Technical Data, Rev. 15 128 Freescale Semiconductor Preliminary Flash Access Blocking Mechanisms Flash Memory SYS_CLK 2 input clock 7 FMCLKD 7 7 DIVIDER FM_CLKDIV JTAG FM_ERASE Figure 7-1 JTAG to FM Connection for Lockout Recovery Two examples of FM_CLKDIV calculations follow. EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been set up, the input clock will be below 12.8MHz, so PRDIV8 = FM_CLKDIV[6] = 0. Using the following equation yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a clock of 190kHz. This translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively. 150[kHz] ( < SYS_CLK (2) (DIV + 1) )< 200[kHz] EXAMPLE 2: In this example, the system clock has been set up with a value of 32MHz, making the FM input clock 16MHz. Because that is greater than 12.8MHz, PRDIV8 = FM_CLKDIV[6] = 1. Using the following equation yields a DIV value of 9 for a clock of 200kHz, and a DIV value of 10 for a clock of 181kHz. This translates to an FM_CLKDIV[6:0] value of $49 or $4A, respectively. 150[kHz] ( < SYS_CLK (2) (DIV + 1) )< 200[kHz] Once the LOCKOUT_RECOVERY instruction has been shifted into the instruction register, the clock divider value must be shifted into the corresponding 7-bit data register. After the data register has been updated, the user must transition the TAP controller into the RUN-TEST/IDLE state for the lockout sequence to commence. The controller must remain in this state until the erase sequence has completed. For details, see the JTAG Section in the 56F8300 Peripheral User Manual. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 129 Note: Once the lockout recovery sequence has completed, the user must reset both the JTAG TAP controller (by asserting TRST) and the device (by asserting external chip reset) to return to normal unsecured operation. 7.2.4 Product Analysis The recommended method of unsecuring a programmed device for product analysis of field failures is via the backdoor key access. The customer would need to supply Technical Support with the backdoor key and the protocol to access the backdoor routine in the Flash. Additionally, the KEYEN bit that allows backdoor key access must be set. An alternative method for performing analysis on a secured hybrid controller would be to mass-erase and reprogram the Flash with the original code, but modify the security bytes. To insure that a customer does not inadvertently lock himself out of the device during programming, it is recommended that he program the backdoor access key first, his application code second, and the security bytes within the FM configuration field last. Part 8 General Purpose Input/Output (GPIO) 8.1 Introduction This section is intended to supplement the GPIO information found in the 56F8300 Peripheral User Manual and contains only chip-specific information. This information supercedes the generic information in the 56F8300 Peripheral User Manual. 8.2 Memory Maps The width of the GPIO port defines how many bits are implemented in each of the GPIO registers. Based on this and the default function of each of the GPIO pins, the reset values of the GPIOx_PUR and GPIOx_PER registers change from port to port. Tables 4-29 through 4-34 define the actual reset values of these registers. 8.3 Configuration There are six GPIO ports defined on the 56F8346/56F8146. The width of each port and the associated peripheral function is shown in Table 8-1 and Table 8-2.

The term “5V-tolerant” refers to the capability of an I/O pin, built on a 3.3V-compatible process technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture of devices designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V- and 56F8346 Technical Data, Rev. 15 136 Freescale Semiconductor Preliminary General Characteristics 5V-compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V ± 10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the power savings of 3.3V I/O levels combined with the ability to receive 5V levels without damage. Absolute maximum ratings in Table 10-1 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. Note: All specifications meet both Automotive and Industrial requirements unless individual specifications are listed. Note: The 56F8146 device is guaranteed to 40MHz and specified to meet Industrial requirements only; CAN is NOT available on the 56F8146 device. CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. Note: The 56F8146 device is specified to meet Industrial requirements only; CAN is NOT available on the 56F8146 device.

Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application. Determined on 2s2p thermal test board. 2. Junction to ambient thermal resistance, Theta-JA (RθJA) was simulated to be equivalent to the JEDEC specification JESD51-2 in a horizontal configuration in natural convection. Theta-JA was also simulated on a thermal test board with two internal planes (2s2p, where “s” is the number of signal layers and “p” is the number of planes) per JESD51-6 and JESD51-7. The correct name for Theta-JA for forced convection or with the non-single layer boards is Theta-JMA. 3. Junction to case thermal resistance, Theta-JC (RθJC ), was simulated to be equivalent to the measured values using the cold plate technique with the cold plate temperature used as the "case" temperature. The basic cold plate measurement technique is described by MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when the package is being used with a heat sink. 4. Thermal Characterization Parameter, Psi-JT (ΨJT ), is the "resistance" from junction to reference point thermocouple on top center of case as defined in JESD51-2. ΨJT is a useful value to use to estimate junction temperature in steady-state customer environments. 5. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance. 6. See Part 12.1 for more details on thermal design considerations. 7.

The data was taken on 15 parts: three each from four processing corner lots as well as three from one nominally processed lot, each at three temperatures: -40°C, 27°C, and 150°C (giving the 45 data points shown above), for two input DC voltages: 0.60V and 2.70V. The data indicates that for the given population of parts, calibration significantly reduced (by as much as 39%) the collective variation (spread) of the absolute error of the population. It also significantly reduced (by as much as 80%) the mean (average) of the absolute error and thereby brought it significantly closer to the ideal value of zero. Although not guaranteed, it is believed that calibration will produce results similar to those shown above for any population of parts including those which represent processing and temperature extremes. 10.17 Equivalent Circuit for ADC Inputs Figure 10-23 illustrates the ADC input circuit during sample and hold. S1 and S2 are always open/closed 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 163 at the same time that S3 is closed/open. When S1/S2 are closed & S3 is open, one input of the sample and hold circuit moves to VREFH - VREFH / 2, while the other charges to the analog input voltage. When the switches are flipped, the charge on C1 and C2 are averaged via S3, with the result that a single-ended analog input is switched to a differential voltage centered about VREFH - VREFH / 2. The switches switch on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). Note that there are additional capacitances associated with the analog input pad, routing, etc., but these do not filter into the S/H output voltage, as S1 provides isolation during the charge-sharing phase. One aspect of this circuit is that there is an on-going input current, which is a function of the analog input voltage, VREF and the ADC clock frequency.

Power consumption is given by the following equation: Total power = A: +B: +C: +D: +E: internal [static component] internal [state-dependent component] internal [dynamic component] external [dynamic component] external [static] A, the internal [static component], is comprised of the DC bias currents for the oscillator, leakage current, PLL, and voltage references. These sources operate independently of processor state or operating frequency. B, the internal [state-dependent component], reflects the supply current required by certain on-chip resources only when those resources are in use. These include RAM, Flash memory and the ADCs. C, the internal [dynamic component], is classic C*V2*F CMOS power dissipation corresponding to the 56800E core and standard cell logic. D, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading on the external pins of the chip. This is also commonly described as C*V2*F, although simulations on two of the IO cell types used on the device reveal that the power-versus-load curve does have a non-zero Y-intercept. Table 10-25 IO Loading Coefficients at 10MHz Intercept PDU08DGZ_ME PDU04DGZ_ME 1.3 1.15mW Slope 0.11mW / pF 0.11mW / pF Power due to capacitive loading on output pins is (first order) a function of the capacitive load and frequency at which the outputs change. Table 10-25 provides coefficients for calculating power dissipated in the IO cells as a function of capacitive load. In these cases: TotalPower = Σ((Intercept +Slope*Cload)*frequency/10MHz) where: • • Summation is performed over all output pins with capacitive loads TotalPower is expressed in mW 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 165 • Cload is expressed in pF Because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found to be fairly low when averaged over a period of time. The one possible exception to this is if the chip is using the external address and data buses at a rate approaching the maximum system rate. In this case, power from these buses can be significant. E, the external [static component], reflects the effects of placing resistive loads on the outputs of the device. Sum the total of all V2/R or IV to arrive at the resistive load contribution to power. Assume V = 0.5 for the purposes of these rough calculations. For instance, if there is a total of 8 PWM outputs driving 10mA into LEDs, then P = 8*.5*.01 = 40mW. In previous discussions, power consumption due to parasitics associated with pure input pins is ignored, as it is assumed to be negligible. 56F8346 Technical Data, Rev. 15 166 Freescale Semiconductor Preliminary 56F8346 Package and Pin-Out Information Part 11 Packaging 11.1 56F8346 Package and Pin-Out Information This section contains package and pin-out information for the 56F8346.

Part 12 Design Considerations 12.1 Thermal Design Considerations An estimation of the chip junction temperature, TJ, can be obtained from the equation: TJ = TA + (RθJΑ x PD) where: TA = Ambient temperature for the package (oC) RθJΑ = Junction-to-ambient thermal resistance (oC/W) PD = Power dissipation in the package (W) The junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy estimation of thermal performance. Unfortunately, there are two values in common usage: the value determined on a single-layer board and the value obtained on a board with two planes. For packages such as the PBGA, these values can be different by a factor of two. Which value is closer to the application depends on the power dissipated by other components on the board. The value obtained on a single-layer board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the internal planes is usually appropriate if the board has low-power dissipation and the components are well separated. When a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: RθJΑ = RθJC + RθCΑ where: RθJA RθJC RθCA = Package junction-to-ambient thermal resistance °C/W = Package junction-to-case thermal resistance °C/W = Package case-to-ambient thermal resistance °C/W RθJC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, RθCA . For instance, the user can change the size of the heat sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit board, or change the thermal dissipation on the printed circuit board surrounding the device. To determine the junction temperature of the device in the application when heat sinks are not used, the Thermal Characterization Parameter (ΨJT) can be used to determine the junction temperature with a measurement of the temperature at the top center of the package case using the following equation: TJ = TT + (ΨJT x PD) 56F8346 Technical Data, Rev. 15 174 Freescale Semiconductor Preliminary Electrical Design Considerations where: TT = Thermocouple temperature on top of package (oC) ΨJT = Thermal characterization parameter (oC)/W PD = Power dissipation in package (W) The thermal characterization parameter is measured per JESD51-2 specification using a 40-gauge type T thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so that the thermocouple junction rests on the package. A small amount of epoxy is placed over the thermocouple junction and over about 1mm of wire extending from the junction. The thermocouple wire is placed flat against the package case to avoid measurement errors caused by cooling effects of the thermocouple wire. When heat sink is used, the junction temperature is determined from a thermocouple inserted at the interface between the case of the package and the interface material. A clearance slot or hole is normally required in the heat sink. Minimizing the size of the clearance is important to minimize the change in thermal performance caused by removing part of the thermal interface to the heat sink. Because of the experimental difficulties with this technique, many engineers measure the heat sink temperature and then back-calculate the case temperature using a separate measurement of the thermal resistance of the interface. From this case temperature, the junction temperature is determined from the junction-to-case thermal resistance. 12.2 Electrical Design Considerations CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. Use the following list of considerations to assure correct device operation: • • Provide a low-impedance path from the board power supply to each VDD pin on the device, and from the board ground to each VSS (GND) pin The minimum bypass requirement is to place six 0.01–0.1μF capacitors positioned as close as possible to the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each of the VDD/VSS pairs, including VDDA/VSSA. Ceramic and tantalum capacitors tend to provide better performance tolerances. 56F8346 Technical Data, Rev. 15 Freescale Semiconductor Preliminary 175 • • • • • Ensure that capacitor leads and associated printed circuit traces that connect to the chip VDD and VSS (GND) pins are less than 0.5 inch per capacitor lead Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for VDD and VSS Bypass the VDD and VSS layers of the PCB with approximately 100 μF, preferably with a high-grade capacitor such as a tantalum capacitor Because the device’s output signals have fast rise and fall times, PCB trace lengths should be minimal Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VDD and VSS circuits. Take special care to minimize noise levels on the VREF, VDDA and VSSA pins Designs that utilize the TRST pin for JTAG port or EOnCE module functionality (such as development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means to assert TRST independently of RESET. Designs that do not require debugging functionality, such as consumer products, should tie these pins together. Because the Flash memory is programmed through the JTAG/EOnCE port, the designer should provide an interface to this port to allow in-circuit Flash programming • • • 12.3 Power Distribution and I/O Ring Implementation Figure 12-1 illustrates the general power control incorporated in the 56F8346/56F8146. This chip contains two internal power regulators. One of them is powered from the VDDA_OSC_PLL pin and cannot be turned off. This regulator controls power to the internal clock generation circuitry. The other regulator is powered from the VDD_IO pins and provides power to all of the internal digital logic of the core, all peripherals and the internal memories. This regulator can be turned off, if an external VDD_CORE voltage is externally applied to the VCAP pins. In summary, the entire chip can be supplied from a single 3.3 volt supply if the large core regulator is enabled. If the regulator is not enabled, a dual supply 3.3V/2.5V configuration can also be used. Notes: • • • Flash, RAM and internal logic are powered from the core regulator output VPP1 and VPP2 are not connected in the customer system All circuitry, analog and digital, shares a common VSS bus 56F8346 Technical Data, Rev. 15 176 Freescale Semiconductor Preliminary Power Distribution and I/O Ring Implementation VDDA_OSC_PLL VDD VCAP I/O CORE OSC VSS VDDA_ADC VREFH VREFP VREFMID VREFN VREFLO REG REG ADC VSSA_ADC Figure 12-1 Power Management Part 13 Ordering Information Table 13-1 lists the pertinent information needed to place an order.
