DSP56321 Block Diagram The Freescale DSP56321, a member of the DSP56300 DSP family, supports networking, security encryption, and home entertainment using a high-performance, single-clock-cycle-per- instruction engine (DSP56000 codecompatible), a barrel shifter, 24-bit addressing, an instruction cache, and a direct memory access (DMA) controller (see Figure 1). The DSP56321 offers 275 million multiply- accumulates per second (MMACS) performance, attaining 550 MMACS when the EFCOP is in use. It operates with an internal 275 MHz clock with a 1.6 volt core and independent 3.3 volt input/output (I/O) power. By operating in parallel with the core, the EFCOP provides overall enhanced performance and signal quality with no impact on channel throughput or total channel support. This device is pin-compatible with the Freescale DSP56303, DSP56L307, DSP56309, and DSP56311. © Freescale Semiconductor, Inc., 2001, 2005.

Signal Name A[0–17] 1.4.2 Type Output State During Reset, Stop, or Wait Tri-stated Signal Description Address Bus—When the DSP is the bus master, A[0–17] are active-high outputs that specify the address for external program and data memory accesses. Otherwise, the signals are tri-stated. To minimize power dissipation, A[0–17] do not change state when external memory spaces are not being accessed. External Data Bus Table 1-6. Signal Name D[0–23] 1.4.3 External Address Bus Signals Type Input/ Output State During Reset Ignored Input External Data Bus Signals State During Stop or Wait Last state: Input: Ignored Output: Last value Signal Description Data Bus—When the DSP is the bus master, D[0–23] are active-high, bidirectional input/outputs that provide the bidirectional data bus for external program and data memory accesses. Otherwise, D[0–23] drivers are tristated. If the last state is output, these lines have weak keepers to maintain the last output state if all drivers are tristated. External Bus Control Table 1-7. Signal Name Type State During Reset, Stop, or Wait External Bus Control Signals Signal Description AA[0–3] Output Tri-stated Address Attribute—When defined as AA, these signals can be used as chip selects or additional address lines. The default use defines a priority scheme under which only one AA signal can be asserted at a time. Setting the AA priority disable (APD) bit (Bit 14) of the Operating Mode Register, the priority mechanism is disabled and the lines can be used together as four external lines that can be decoded externally into 16 chip select signals. RD Output Tri-stated Read Enable—When the DSP is the bus master, RD is an active-low output that is asserted to read external memory on the data bus (D[0–23]). Otherwise, RD is tri-stated. WR Output Tri-stated Write Enable—When the DSP is the bus master, WR is an active-low output that is asserted to write external memory on the data bus (D[0–23]). Otherwise, the signals are tri-stated. DSP56321 Technical Data, Rev. 11 1-4 Freescale Semiconductor External Memory Expansion Port (Port A) Table 1-7. Signal Name TA Type Input External Bus Control Signals (Continued) State During Reset, Stop, or Wait Ignored Input Signal Description Transfer Acknowledge—If the DSP56321 is the bus master and there is no external bus activity, or the DSP56321 is not the bus master, the TA input is ignored. The TA input is a data transfer acknowledge (DTACK) function that can extend an external bus cycle indefinitely. Any number of wait states (1, 2. . .infinity) can be added to the wait states inserted by the bus control register (BCR) by keeping TA deasserted. In typical operation, TA is deasserted at the start of a bus cycle, is asserted to enable completion of the bus cycle, and is deasserted before the next bus cycle. The current bus cycle completes one clock period after TA is asserted synchronous to CLKOUT. The number of wait states is determined by the TA input or by the BCR, whichever is longer. The BCR can be used to set the minimum number of wait states in external bus cycles. To use the TA functionality, the BCR must be programmed to at least one wait state. A zero wait state access cannot be extended by TA deassertion; otherwise, improper operation may result. BR Output Reset: Output (deasserted) State during Stop/Wait depends on BRH bit setting: • BRH = 0: Output (deasserted) • BRH = 1: Maintains last state (that is, if asserted, remains asserted) BG Input Ignored Input Bus Request—Asserted when the DSP requests bus mastership. BR is deasserted when the DSP no longer needs the bus. BR may be asserted or deasserted independently of whether the DSP56321 is a bus master or a bus slave. Bus “parking” allows BR to be deasserted even though the DSP56321 is the bus master. (See the description of bus “parking” in the BB signal description.) The bus request hold (BRH) bit in the BCR allows BR to be asserted under software control even though the DSP does not need the bus. BR is typically sent to an external bus arbitrator that controls the priority, parking, and tenure of each master on the same external bus. BR is affected only by DSP requests for the external bus, never for the internal bus. During hardware reset, BR is deasserted and the arbitration is reset to the bus slave state. Bus Grant—Asserted by an external bus arbitration circuit when the DSP56321 becomes the next bus master. When BG is asserted, the DSP56321 must wait until BB is deasserted before taking bus mastership. When BG is deasserted, bus mastership is typically given up at the end of the current bus cycle. This may occur in the middle of an instruction that requires more than one external bus cycle for execution. To ensure proper operation, the user must set the asynchronous bus arbitration enable (ABE) bit (Bit 13) in the Operating Mode Register. When this bit is set, BG and BB are synchronized internally. This adds a required delay between the deassertion of an initial BG input and the assertion of a subsequent BG input. BB Input/ Output Ignored Input Bus Busy—Indicates that the bus is active. Only after BB is deasserted can the pending bus master become the bus master (and then assert the signal again). The bus master may keep BB asserted after ceasing bus activity regardless of whether BR is asserted or deasserted. Called “bus parking,” this allows the current bus master to reuse the bus without rearbitration until another device requires the bus. BB is deasserted by an “active pull-up” method (that is, BB is driven high and then released and held high by an external pull-up resistor). Notes: 1. 2. See BG for additional information. BB requires an external pull-up resistor. DSP56321 Technical Data, Rev. 11 Freescale Semiconductor 1-5 Signals/Connections 1.5 Interrupt and Mode Control The interrupt and mode control signals select the chip operating mode as it comes out of hardware reset. After RESET is deasserted, these inputs are hardware interrupt request lines. Table 1-8. Signal Name Type State During Reset Schmitt-trigger Input Interrupt and Mode Control Signal Description MODA Input Mode Select A—MODA, MODB, MODC, and MODD select one of 16 initial chip operating modes, latched into the Operating Mode Register when the RESET signal is deasserted. IRQA Input MODB Input IRQB Input MODC Input IRQC Input MODD Input IRQD Input RESET Input Schmitt-trigger Input Reset—Places the chip in the Reset state and resets the internal phase generator. The Schmitt-trigger input allows a slowly rising input (such as a capacitor charging) to reset the chip reliably. When the RESET signal is deasserted, the initial chip operating mode is latched from the MODA, MODB, MODC, and MODD inputs. The RESET signal must be asserted after powerup. PINIT Input Schmitt-trigger Input PLL Initial—During assertion of RESET, the value of PINIT determines whether the DPLL is enabled or disabled. NMI Input External Interrupt Request A—After reset, this input becomes a levelsensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. If the processor is in the STOP or WAIT standby state and IRQA is asserted, the processor exits the STOP or WAIT state. Schmitt-trigger Input Mode Select B—MODA, MODB, MODC, and MODD select one of 16 initial chip operating modes, latched into the Operating Mode Register when the RESET signal is deasserted. External Interrupt Request B—After reset, this input becomes a levelsensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. If the processor is in the WAIT standby state and IRQB is asserted, the processor exits the WAIT state. Schmitt-trigger Input Mode Select C—MODA, MODB, MODC, and MODD select one of 16 initial chip operating modes, latched into the Operating Mode Register when the RESET signal is deasserted. External Interrupt Request C—After reset, this input becomes a levelsensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. If the processor is in the WAIT standby state and IRQC is asserted, the processor exits the WAIT state. Schmitt-trigger Input Mode Select D—MODA, MODB, MODC, and MODD select one of 16 initial chip operating modes, latched into the Operating Mode Register when the RESET signal is deasserted. External Interrupt Request D—After reset, this input becomes a levelsensitive or negative-edge-triggered, maskable interrupt request input during normal instruction processing. If the processor is in the WAIT standby state and IRQD is asserted, the processor exits the WAIT state. Nonmaskable Interrupt—After RESET deassertion and during normal instruction processing, this Schmitt-trigger input is the negative-edge-triggered NMI request.

The HI08 supports a variety of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs, and DMA hardware. 1.6.1 Host Port Usage Considerations Careful synchronization is required when the system reads multiple-bit registers that are written by another asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the Host port). The considerations for proper operation are discussed in Table 1-9. Table 1-9. Host Port Usage Considerations Action Description Asynchronous read of receive byte registers When reading the receive byte registers, Receive register High (RXH), Receive register Middle (RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data in the receive byte registers is valid. Asynchronous write to transmit byte registers The host interface programmer should not write to the transmit byte registers, Transmit register High (TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees that the transmit byte registers transfer valid data to the Host Receive (HRX) register. Asynchronous write to host vector The host interface programmer must change the Host Vector (HV) register only when the Host Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a stable vector. 1.6.2 Host Port Configuration HI08 signal functions vary according to the programmed configuration of the interface as determined by the 16 bits in the HI08 Port Control Register. Table 1-10.

The OnCE module provides a means to interface nonintrusively with the DSP56300 core and its peripherals so that you can examine registers, memory, or on-chip peripherals. Functions of the OnCE module are provided through the JTAG TAP signals. For programming models, see the chapter on debugging support in the DSP56300 Family Manual. Table 1-15. Signal Name JTAG/OnCE Interface Type State During Reset TCK Input Input Test Clock—A test clock input signal to synchronize the JTAG test logic. TDI Input Input Test Data Input—A test data serial input signal for test instructions and data. TDI is sampled on the rising edge of TCK and has an internal pull-up resistor. TDO Output Tri-stated Test Data Output—A test data serial output signal for test instructions and data. TDO is actively driven in the shift-IR and shift-DR controller states. TDO changes on the falling edge of TCK. TMS Input Input Test Mode Select—Sequences the test controller’s state machine. TMS is sampled on the rising edge of TCK and has an internal pull-up resistor. TRST Input Input Test Reset—Initializes the test controller asynchronously. TRST has an internal pull-up resistor. TRST must be asserted during and after power-up (see EB610/D for details). Input/ Output Input Debug Event—As an input, initiates Debug mode from an external command controller, and, as an open-drain output, acknowledges that the chip has entered Debug mode. As an input, DE causes the DSP56300 core to finish executing the current instruction, save the instruction pipeline information, enter Debug mode, and wait for commands to be entered from the debug serial input line. This signal is asserted as an output for three clock cycles when the chip enters Debug mode as a result of a debug request or as a result of meeting a breakpoint condition. The DE has an internal pull-up resistor. DE Signal Description This signal is not a standard part of the JTAG TAP controller. The signal connects directly to the OnCE module to initiate debug mode directly or to provide a direct external indication that the chip has entered Debug mode. All other interface with the OnCE module must occur through the JTAG port. DSP56321 Technical Data, Rev. 11 1-14 Freescale Semiconductor 2 Specifications The DSP56321 is fabricated in high-density CMOS with Transistor-Transistor Logic (TTL) compatible inputs and outputs. 2.1 Maximum Ratings CAUTION This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. Reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or VCC). In the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a “maximum” value for a specification never occurs in the same device that has a “minimum” value for another specification; adding a maximum to a minimum represents a condition that can never exist.

Refers to MODA/IRQA, MODB/IRQB, MODC/IRQC, and MODD/IRQD pins. Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. To obtain these results, all inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP benchmarks (see Appendix A). The power consumption numbers in this specification are 90 percent of the measured results of this benchmark. This reflects typical DSP applications. To obtain these results, all inputs must be terminated (that is, not allowed to float). To obtain these results, all inputs not disconnected at Stop mode must be terminated (that is, not allowed to float), and the DPLL and on-chip crystal oscillator must be disabled. Periodically sampled and not 100 percent tested. VCCQH = 3.3 V ± 0.3 V, VCQLC = 1.6 V ± 0.1 V; TJ = –40°C to +100 °C, CL = 50 pF This characteristic does not apply to XTAL. Driving EXTAL to the low VIHX or the high VILX value may cause additional power consumption (DC current). To minimize power consumption, the minimum VIHX should be no lower than 0.9 × VCCQH and the maximum VILX should be no higher than 0.1 × VCCQH . 2.4 AC Electrical Characteristics The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.3 V and a VIH minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Notes 7 and 9 of the previous table. AC timing specifications, which are referenced to a device input signal, are measured in production with respect to the 50 percent point of the respective input signal’s transition. DSP56321 output levels are measured with the production test machine VOL and VOH reference levels set at 0.4 V and 2.4 V, respectively. Note: Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 16 MHz and rated speed with the DPLL enabled. 2.4.1 Internal Clocks Table 2-4.

The external square wave source connects to EXTAL and XTAL is not used. Figure 2-2 shows the EXTAL input signal. VILX ETH ETL 2 3 4 Note: The midpoint is 0.5 (VIHX + VILX).

To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended when fast interrupts are used. Long interrupts are recommended for Level-sensitive mode. This timing depends on several settings: • For DPLL disable, using internal oscillator (DPLL Control Register (PCTL) Bit 2 = 0) and oscillator disabled during Stop (PCTL Bit 1 = 0), a stabilization delay is required to assure that the oscillator is stable before programs are executed. Resetting the Stop delay (Operating Mode Register Bit 6 = 0) provides the proper delay. While Operating Mode Register Bit 6 = 1 can be set, it is not recommended, and these specifications do not guarantee timings for that case. • For DPLL disable, using internal oscillator (PCTL Bit 2 = 0) and oscillator enabled during Stop (PCTL Bit 1 = 1), no stabilization delay is required and recovery is minimal (Operating Mode Register Bit 6 setting is ignored). • For DPLL disable, using external clock (PCTL Bit 2 = 1), no stabilization delay is required and recovery time is defined by the PCTL Bit 1 and Operating Mode Register Bit 6 settings. • For DPLL enable, if PCTL Bit 1 is 0, the DPLL is shut down during Stop. Recovering from Stop requires the DPLL to lock. The DPLL lock procedure duration is defined in Table 2-6 and will be refined after silicon characterization. This procedure is followed by the stop delay counter. Stop recovery ends when the stop delay counter completes its count. • The DPLT value for DPLL disable is 0. Periodically sampled and not 100 percent tested. For an external clock generator, RESET duration is measured while RESET is asserted, VCC is valid, and the EXTAL input is active and valid. For an internal oscillator, RESET duration is measured while RESET is asserted and VCC is valid. The specified timing reflects the crystal oscillator stabilization time after power-up. This number is affected both by the specifications of the crystal and other components connected to the oscillator and reflects worst case conditions. When the VCC is valid, but the other “required RESET duration” conditions (as specified above) have not been yet met, the device circuitry is in an uninitialized state that can result in significant power consumption and heat-up. Designs should minimize this state to the shortest possible duration. VCCQH = 3.3 V ± 0.3 V, VCCQL = 1.6 V ± 0.1 V; TJ = –40°C to +100°C, C L = 50 pF. WS = number of wait states (measured in clock cycles, number of TC). Use the expression to compute a maximum value. VIH RESET 9 10 8 All Pins Reset Value First Fetch A[0–17] Figure 2-3.

To guarantee timings 250 and 251, it is recommended that you assert non-overlapping BG inputs to different DSP56300 devices (on the same bus), as shown in Figure 2-12, where BG1 is the BG signal for one DSP56300 device while BG2 is the BG signal for a second DSP56300 device. DSP56321 Technical Data, Rev. 11 Freescale Semiconductor 2-13 Specifications BG1 BB 250 BG2 251 250+251 Figure 2-12. Asynchronous Bus Arbitration Timing The asynchronous bus arbitration is enabled by internal synchronization circuits on BG and BB inputs. These synchronization circuits add delay from the external signal until it is exposed to internal logic. As a result of this delay, a DSP56300 part may assume mastership and assert BB, for some time after BG is deasserted. This is the reason for timing 250. Once BB is asserted, there is a synchronization delay from BB assertion to the time this assertion is exposed to other DSP56300 components that are potential masters on the same bus. If BG input is asserted before that time, and BG is asserted and BB is deasserted, another DSP56300 component may assume mastership at the same time. Therefore, some non-overlap period between one BG input active to another BG input active is required. Timing 251 ensures that overlaps are avoided. 2.4.6 Host Interface Timing Table 2-10. 200 MHz Characteristic10 No. 317 Read data strobe assertion width HACK assertion width Host Interface Timings1,2,12 220 MHz 240 MHz 275 MHz Expression 5 TC + 4.95 318 Read data strobe deassertion width5 HACK deassertion width 319 Read data strobe deassertion width5 after “Last Data Register” reads8,11, or between two consecutive CVR, ICR, or ISR reads3 HACK deassertion width after “Last Data Register” reads8,11 2.5 × TC + 3.3 320 Write data strobe assertion width6 Uni t Min Max Min Max Min Max Min Max 9.95 — 9.05 — 8.3 — 7.77 — ns 4.95 — 4.5 — 4.13 — 4.0 — ns 15.8 — 14.7 — 13.7 — 12.39 — ns 6.6 — 6.0 — 5.5 — 5.1 — ns 15.8 — 14.7 — 13.7 — 12.39 — ns 8.25 — 7.5 — 6.88 — 6.28 — ns 4.95 — 4.5 — 4.13 — 4.0 — ns width8 321 Write data strobe deassertion HACK write deassertion width • after ICR, CVR and “Last Data Register” writes • after IVR writes, or after TXH:TXM:TXL writes (with HLEND= 0), or after TXL:TXM:TXH writes (with HLEND = 1) 322 HAS assertion width 2.5 × TC + 3.3 DSP56321 Technical Data, Rev. 11 2-14 Freescale Semiconductor AC Electrical Characteristics Host Interface Timings1,2,12 (Continued) Table 2-10.

The “Last Data Register” is the register at address $7, which is the last location to be read or written in data transfers. This is RXL/TXL in the Big Endian mode (HLEND = 0; HLEND is the Interface Control Register bit 7—ICR[7]), or RXH/TXH in the Little Endian mode (HLEND = 1). 9. In this calculation, the host request signal is pulled up by a 4.7 kΩ resistor in the Open-drain mode. 10. VCCQH = 3.3 V ± 0.3 V, VCCQL = 1.6 V ± 0.1 V; TJ = –40°C to +100 °C, CL = 50 pF 11. This timing is applicable only if a read from the “Last Data Register” is followed by a read from the RXL, RXM, or RXH registers without first polling RXDF or HREQ bits, or waiting for the assertion of the HREQ signal. 12. After the external host writes a new value to the ICR, the HI08 will be ready for operation after three DSP clock cycles (3 × Tc). 1. 2. 3. 4. 317 318 HACK 328 327 326 329 H[0–7] HREQ Figure 2-13.

Timer Interrupt Generation 2.4.10 Considerations For GPIO Use The following considerations can be helpful when GPIO is used. 2.4.10.1 GPIO as Output • The time from fetch of the instruction that changes the GPIO pin to the actual change is seven core clock cycles, if the instruction is a one-cycle instruction and there are no pipeline stalls or any other pipeline delays. • The maximum rise or fall time of a GPIO pin is 13 ns (TTL levels, assuming that the maximum of 50 pF load limit is met). 2.4.10.2 GPIO as Input GPIO inputs are not synchronized with the core clock. When only one GPIO bit is polled, this lack of synchronization presents no problem, since the read value can be either the previous value or the new value of the corresponding GPIO pin. However, there is the risk of reading an intermediate state if: • Two or more GPIO bits are treated as a coupled group (for example, four possible status states encoded in two bits). • The read operation occurs during a simultaneous change of GPIO pins (for example, the change of 00 to 11 may happen through an intermediate state of 01 or 10). Therefore, when GPIO bits are read, the recommended practice is to poll continuously until two consecutive read operations have identical results.

Most connections supply a single signal. Some connections provide a signal with dual functionality, such as the MODx/IRQx pins that select an operating mode after RESET is deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars, such as HAS/HAS. Some connections have two or more configurable functions; names assigned to these connections indicate the function for a specific configuration. For example, connection N2 is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin. Unlike the TQFP package, most of the GND pins are connected internally in the center of the connection array and act as heat sink for the chip.

DSP56321 Mechanical Information, 196-pin MAP-BGA Package DSP56321 Technical Data, Rev. 11 3-10 Freescale Semiconductor Design Considerations 4 This section describes various areas to consider when incorporating the DSP56321 device into a system design. 4.1 Thermal Design Considerations An estimate of the chip junction temperature, T J, in ° C can be obtained from this equation: Equation 1: T J = T A + ( P D × R θJA ) Where: TA RθJA PD = = = ambient temperature °C package junction-to-ambient thermal resistance °C/W power dissipation in package Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a caseto-ambient thermal resistance, as in this equation: Equation 2: R θJA = R θJC + R θCA 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 example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board (PCB) or otherwise change the thermal dissipation capability of the area surrounding the device on a PCB. This model is most useful for ceramic packages with heat sinks; some 90 percent of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the PCB, analysis of the device thermal performance may need the additional modeling capability of a system-level thermal simulation tool. The thermal performance of plastic packages is more dependent on the temperature of the PCB to which the package is mounted. Again, if the estimates obtained from RθJA do not satisfactorily answer whether the thermal performance is adequate, a system-level model may be appropriate. A complicating factor is the existence of three common ways to determine the junction-to-case thermal resistance in plastic packages. • To minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. DSP56321 Technical Data, Rev. 11 Freescale Semiconductor 4-1 Design Considerations • To define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to the point at which the leads attach to the case. • If the temperature of the package case (TT) is determined by a thermocouple, thermal resistance is computed from the value obtained by the equation (TJ – TT)/PD. As noted earlier, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. From a practical standpoint, that value is also suitable to determine the junction temperature from a case thermocouple reading in forced convection environments. In natural convection, the use of the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will yield an estimate of a junction temperature slightly higher than actual temperature. Hence, the new thermal metric, thermal characterization parameter or ΨJT, has been defined to be (TJ – TT)/PD. This value gives a better estimate of the junction temperature in natural convection when the surface temperature of the package is used. Remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy. 4.2 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 logic voltage level (for example, either GND or VCC). Use the following list of recommendations to ensure correct DSP operation. • Provide a low-impedance path from the board power supply to each VCC pin on the DSP and from the board ground to each GND pin. • Use at least four 0.01–0.1 µF bypass capacitors for VCCQL (core) and at least six 0.01–0.1 µF bypass capacitors for the other VCC (I/O) power connections positioned as closely as possible to the four sides of the package to connect the power sources to GND. • Ensure that capacitor leads and associated printed circuit traces that connect to the chip VCC and GND pins are less than 0.5 inch per capacitor lead. • Use at least a four-layer PCB with two inner layers for VCC and GND. • Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal. This recommendation particularly applies to the address and data buses as well as the IRQA, IRQB, IRQC, IRQD, TA, and BG pins. Maximum PCB trace lengths on the order of 6 inches are recommended. DSP56321 Technical Data, Rev. 11 4-2 Freescale Semiconductor Power Consumption Considerations • Consider all device loads as well as parasitic capacitance due to PCB traces when you calculate capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VCC and GND circuits. • All inputs must be terminated (that is, not allowed to float) by CMOS levels except for the three pins with internal pull-up resistors (TRST, TMS, DE). • The following pins must be asserted during the power-up sequence: RESET and TRST. A stable EXTAL signal should be supplied before deassertion of RESET. If the VCC reaches the required level before EXTAL is stable or other “required RESET duration” conditions are met (see Table 2-7), the device circuitry can be in an uninitialized state that may result in significant power consumption and heat-up. Designs should minimize this condition to the shortest possible duration. • Ensure that during power-up, and throughout the DSP56321 operation, VCCQH is always higher or equal to the VCCQL voltage level. • If multiple DSP devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices. • The Port A data bus (D[0–23]), HI08, ESSI0, ESSI1, SCI, and timers all use internal keepers to maintain the last output value even when the internal signal is tri-stated. Typically, no pull-up or pull-down resistors should be used with these signal lines. However, if the DSP is connected to a device that requires pull-up resistors (such as an MPC8260), the recommended resistor value is 10 KΩ or less. If more than one DSP must be connected in parallel to the other device, the pull-up resistor value requirement changes as follows: — — — — — 2 DSPs = 5 KΩ (mask sets 0K91M and 1K91M)/7 KΩ (mask set 0K93M) or less 3 DSPs = 3 KΩ (mask sets 0K91M and 1K91M)/4 KΩ (mask set 0K93M) or less 4 DSPs = 2 KΩ (mask sets 0K91M and 1K91M)/3 KΩ (mask set 0K93M) or less 5 DSPs = 1.5 KΩ (mask sets 0K91M and 1K91M)/2 KΩ (mask set 0K93M) or less 6 DSPs = 1 KΩ (mask sets 0K91M and 1K91M)/1.5 KΩ (mask set 0K93M) or less Note: Refer to EB610/D DSP56321/DSP56321T Power-Up Sequencing Guidelines for detailed information about minimizing power consumption during startup. 4.3 Power Consumption Considerations Power dissipation is a key issue in portable DSP applications. Some of the factors affecting current consumption are described in this section. Most of the current consumed by CMOS devices is alternating current (ac), which is charging and discharging the capacitances of the pins and internal nodes. Current consumption is described by this formula: Equation 3: I = C × V × f Where: C V f = = = node/pin capacitance voltage swing frequency of node/pin toggle Example 4-1. Current Consumption For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, with a 66 MHz clock, toggling at its maximum possible rate (33 MHz), the current consumption is expressed in Equation 4. DSP56321 Technical Data, Rev. 11 Freescale Semiconductor 4-3 Design Considerations Equation 4: I = 50 × 10 – 12 × 3.3 × 33 × 10 6 = 5.48 mA The maximum internal current (ICCImax) value reflects the typical possible switching of the internal buses on bestcase operation conditions—not necessarily a real application case. The typical internal current (ICCItyp) value reflects the average switching of the internal buses on typical operating conditions. Perform the following steps for applications that require very low current consumption: 1. Set the EBD bit when you are not accessing external memory. 2. Minimize external memory accesses, and use internal memory accesses. 3. Minimize the number of pins that are switching. 4. Minimize the capacitive load on the pins. 5. Connect the unused inputs to pull-up or pull-down resistors. 6. Disable unused peripherals. 7. Disable unused pin activity (for example, CLKOUT, XTAL). One way to evaluate power consumption is to use a current-per-MIPS measurement methodology to minimize specific board effects (that is, to compensate for measured board current not caused by the DSP). A benchmark power consumption test algorithm is listed in Appendix A. Use the test algorithm, specific test current measurements, and the following equation to derive the current-per-MIPS value. Equation 5: ⁄ MIPS = I ⁄ MHz = ( I typF2 – I typF1 ) ⁄ ( F2 – F1 ) Where: ItypF2 ItypF1 F2 F1 = = = = current at F2 current at F1 high frequency (any specified operating frequency) low frequency (any specified operating frequency lower than F2) Note: F1 should be significantly less than F2. For example, F2 could be 66 MHz and F1 could be 33 MHz. The degree of difference between F1 and F2 determines the amount of precision with which the current rating can be determined for an application. 4.4 Input (EXTAL) Jitter Requirements The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow (that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
