Schmitt trigger input; see ’DC Specifications’, page 31 for triggers points and hysteresis. Input only for JTAG boundary scan mode. Output only for JTAG boundary scan mode. The internal pullup and pull-down resistance on all digital I/O pins is 50 k When used as SMBCLK, this pin must have a resistor. The RESET STATE is defined as the state during power-on reset. The STANDBY STATE is defined as the state when the device is in standby. During this state, I/O cells are forced to input (Input), output driving low (LOW), output driving high (HIGH), or their current state is preserved (No Change).

Application Diagram SYSTEM DESCRIPTIONS ARM922T Processor The LH7A400 microcontroller features the ARM922T cached core with an Advanced High Performance Bus (AHB) interface. The processor is a member of the ARM9T family of processors. For more information, see the ARM document, ‘ARM922T Technical Reference Manual’, available on ARM’s website at www.arm.com. Clock and State Controller The clocking scheme in the LH7A400 is based around two primary oscillator inputs. These are the 14.7456 MHz input crystal and the 32.768 kHz real time clock oscillator. See Figure 5. The 14.7456 MHz oscillator is used to generate the main system clock domains for the LH7A400, where as the 32.768 kHz is used for controlling the power down operations and real time clock peripheral. The clock and state controller provides the clock gating and frequency division necessary, and then supplies the clocks to the processor and to the rest of the system. The amount of clock gating that actually takes place is dependent on the current power saving mode selected. 20 The 32.768 kHz clock provides the source for the Real Time Clock tree and power-down logic.This clock is used for the power state control in the design and is the only clock in the LH7A400 that runs permanently. The 32.768 kHz clock is divided down to 1 Hz using a ripple divider to save power. This generated 1 Hz clock is used in the Real Time Clock counter. The 14.7456 MHz source is used to generate the main system clocks for the LH7A400. It is the source for PLL1 and PLL2, it acts as the primary clock to the peripherals and is the source clock to the Programmable clock (PGM) divider. PLL1 provides the main clock tree for the chip, it generates the following clocks: FCLK, HCLK and PCLK. FCLK is the clock that drives the ARM922T core. HCLK is the main bus (AHB) clock, as such it clocks all memory interfaces, bus arbitrators and the AHB peripherals. HCLK is generated by dividing FCLK by 1, 2, 3, or 4. HCLK can be gated by the system to enable low power operation. PCLK is the peripheral bus (APB) clock. It is generated by dividing HCLK by either 2, 4, or 8. PLL2 is used to generate a fixed frequency of 48 MHz for the USB peripheral.

Clock and State Controller Block Diagram Power Modes Data Paths The LH7A400 has three operational states: Run, Halt, and Standby. In Run mode, all clocks are hardware-enabled and the processor is clocked. Halt mode stops the processor clock while waiting for an event such as a key press, but the device continues to function. Finally, Standby equates to the computer being switched ‘off’, i.e. no display (LCD disabled) and the main oscillator is shut down. The 32.768 kHz oscillator operates in all three modes. Reset Modes There are three external signals that can generate resets to the LH7A400; these are nPOR (power on reset), nPWRFL (power failure) and nURESET (user reset). If any of these are active, a system reset is generated internally. A nPOR reset performs a full system reset. The nPWRFL and nURESET resets will perform a full system reset except for the SDRAM refresh control, SDRAM Global Configuration, SDRAM Device Configuration and the RTC peripheral registers. The SDRAM controller will issue a self-refresh command to external SDRAM before the system enters this reset (the nPWRFL and nURESET resets only, not so for the nPOR reset). This allows the system to maintain its Real Time Clock and SDRAM contents. On coming out of reset, the chip enters Standby mode. Once in Run mode the PWRSR register can be interrogated to determine the nature of the reset, and the trigger source, after which software can then take appropriate actions. Product data sheet The data paths in the LH7A400 are: • The AMBA AHB bus • The AMBA APB bus • The External Bus Interface • The LCD AHB bus • The DMA busses. AMBA AHB BUS The Advanced Microprocessor Bus Architecture Advanced High-performance Bus (AMBA AHB) bus is a high speed 32-bit-wide data bus. The AMBA AHB is for high-performance, high clock frequency system modules. Peripherals that have high bandwidth requirements are connected to the LH7A400 core processor using the AHB bus. These include the external and internal memory interfaces, the LCD registers, palette RAM and the bridge to the Advanced Peripheral Bus (APB) interface. The APB Bridge transparently converts the AHB access into the slower speed APB accesses. All of the control registers for the APB peripherals are programmed using the AHB - APB bridge interface. The main AHB data and address lines are configured using a multiplexed bus. This removes the need for tri-state buffers and bus holders, and simplifies bus arbitration. Rev. 02 — 19 March 2009 21 LH7A400 32-Bit System-on-Chip NXP Semiconductors AMBA APB BUS The AMBA APB bus is a lower-speed 32-bit-wide peripheral data bus. The speed of this bus is selectable to be a divide-by-2, divide-by-4 or divide-by-8 of the speed of the AHB bus. EXTERNAL BUS INTERFACE The External Bus Interface (EBI) provides a 32-bit wide, high speed gateway to external memory devices. The memory devices supported include: • Asynchronous RAM/ROM/Flash The LH7A400 can boot from either synchronous or asynchronous ROM/Flash. The selection is determined by the value of the MEDCHG pin at Power On Reset as shown in Table 8. When booting from synchronous memory, then synchronous bank 4 (nSCS3) is mapped into memory location zero. When booting from asynchronous memory, asynchronous memory bank 0 (nSCS0) is mapped into memory location zero. Figure 6 shows the memory map of the LH7A400 system for the two boot modes. Once the LH7A400 has booted, the boot code can configure the ARM922T MMU to remap the low memory space to a location in RAM. This allows the user to set the interrupt vector table. • Synchronous DRAM/Flash • PCMCIA interfaces • CompactFlash interfaces. The EBI can be controlled by either the Asynchronous memory controller or Synchronous memory controller. There is an arbiter on the EBI input, with priority given to the Synchronous Memory Controller interface. LCD AHB BUS The LCD controller has its own local memory bus that connects it to the system’s embedded memory and external SDRAM. The function of this local data bus is to allow the LCD controller to perform its video refresh function without congesting the AHB bus. This leads to better system performance and lower power consumption. There is an arbiter on both the embedded memory and the synchronous memory controller. In both cases the LCD bus is given priority. DMA BUSES The LH7A400 has a DMA system that connects the higher speed/higher data volume APB peripherals (MMC, USB and AC97) to the AHB bus. This enables the efficient transfer of data between these peripherals and external memory without the intervention of the ARM922T core. The DMA engine does not support memory to memory transfers. Memory Map The LH7A400 system has a 32-bit-wide address bus. This allows it to address up to 4GB of memory. This memory space is subdivided into a number of memory banks; see Figure 6. Four of these banks (each of 256MB) are allocated to the Synchronous memory controller. Eight of the banks (again, each 256MB) are allocated to the Asynchronous memory controller. Two of these eight banks are designed for PCMCIA systems. Part of the remaining memory space is allocated to the embedded SRAM, and to the control registers of the AHB and APB. The rest is unused. 22 Table 8.

Four interrupt sources are mapped to the FIQ input of the ARM922T and 24 are mapped to the IRQ input. FIQs have a higher priority than the IRQs. If two interrupts with the same priority become active at the same time, the priority must be resolved in software. When an interrupt becomes active, the interrupt controller generates an FIQ or IRQ if the corresponding mask bit is set. No latching of interrupts takes place in the controller. After a Power On Reset all mask register bits are cleared, therefore masking all interrupts. Hence, enabling of the mask register must be done by software after a power-on-reset.

Memory Mapping for Each Boot Mode External Bus Interface The external bus interface allows the ARM922T, LCD controller and DMA engine access to an external memory system. The LCD controller has access to an internal frame buffer in embedded SRAM and an extension buffer in Synchronous Memory for large displays. The processor and DMA engine share the main system bus, providing access to all external memory devices and the embedded SRAM frame buffer. An arbitration unit ensures that control over the External Bus Interface (EBI) is only granted when an existing access has been completed. See Figure 7. Embedded SRAM The amount of Embedded SRAM contained in the LH7A400 is 80 kB. This Embedded memory is designed to be used for storing code, data, or LCD frame data and to be contiguous with external SDRAM. The 80 kB is large enough to store a QVGA panel (320 × 240) at 8 bits per pixel, equivalent to 70 kB of information. Containing the frame buffer on chip reduces the overall power consumed in any application that uses the LH7A400. Normally, the system has to perform external accesses to acquire this data. The LCD controller is designed to automatically use an overflow frame buffer in SDRAM if a larger screen size is required. This overflow buffer can be located on any Product data sheet 4 kB page boundary in SDRAM, allowing software to set the MMU (in the LCD controller) page tables such that the two memory areas appear contiguous. Byte, Half-Word and Word accesses are permissible. Asynchronous Memory Controller The Asynchronous memory controller is incorporated as part of the memory controller to provide an interface between the AMBA AHB system bus and external (off-chip) memory devices. The Asynchronous Memory Controller provides support for up to eight independently configurable memory banks simultaneously. Each memory bank is capable of supporting: • SRAM • ROM • Flash EPROM • Burst ROM memory. Each memory bank may use devices using either 8-, 16-, or 32-bit external memory data paths. The memory controller supports only little-endian operation.

External Bus Interface Block Diagram 24 Rev. 02 — 19 March 2009 Product data sheet 32-Bit System-on-Chip NXP Semiconductors The Asynchronous Memory Controller has six main functions: • • • • • • Memory bank select Access sequencing Wait states generation Byte lane write control External bus interface CompactFlash or PCMCIA interfacing. LH7A400 MMC bus lines can be divided into three groups: • Power supply: VDD and VSS • Data Transfer: MMCCMD, MMCDATA • Clock: MMCLK. Synchronous Memory Controller The Synchronous memory controller provides a high speed memory interface to a wide variety of Synchronous memory devices, including SDRAM, Synchronous Flash and Synchronous ROMs. The key features of the controller are: • LCD DMA port for high bandwidth • Up to four Synchronous Memory banks that can be independently set up • Special configuration bits for Synchronous ROM operation • Ability to program Synchronous Flash devices using write and erase commands MULTIMEDIACARD ADAPTER The MultiMediaCard Adapter implements MultiMediaCard specific functions, serves as the bus master for the MultiMediacard Bus and implements the standard interface to the MultiMediaCard Cards (card initialization, CRC generation and validation, command/response transactions, etc.). Smart Card Interface (SCI) The SCI (ISO7816) interfaces to an external Smart Card reader. The SCI can autonomously control data transfer to and from the smart card.

It interfaces directly to STN, color STN, TFT, AD-TFT, and HR-TFT panels. Unlike other LCD controllers, the LH7A400’s LCD Controller incorporates the timing conversion logic from TFT to HR- and AD-TFT, allowing a direct interface to these panels and minimizing external chip count. • USB (1 Tx and 1 Rx DMA Channel) • MMC (1 Tx and 1 Rx DMA Channel) • AC97 (3 Tx and 3 Rx DMA Channels). Each has its own bi-directional peripheral DMA bus capable of transferring data in both directions simultaneously. All memory transfers take place via the main system AHB bus. DMA Specific features are: • Independent DMA channels for Tx and Rx • Two Buffer Descriptors per channel to avoid potential data under/over-flows due to software introduced latency The Color LCD Controller features support for: • Up to 1,024 × 768 Resolution • 16-bit Video Bus • STN, Color STN, AD-TFT, HR-TFT, TFT panels • Single and Dual Scan STN panels • Up to 15 Gray Shades • No Buffer wrapping • Up to 64,000 Colors • Buffer size may be equal to, greater than, or less than the packet size. Transfers can automatically switch between buffers. AC97 Advanced Audio Codec Interface • Maskable interrupt generation • Internal arbitration between DMA Channels and external bus arbiter. • For DMA Data transfer sizes, byte, word and quadword data transfers are supported. A set of control and status registers are available to the system processor for setting up DMA operations and monitoring their status. A system interrupt is generated when any or all of the DMA channels wish to inform the processor that a new buffer needs to be allocated. The DMA controller services three peripherals using ten DMA channels, each with its own peripheral DMA bus capable of transferring data in both directions simultaneously. The MMC and USB peripherals each use two DMA channels, one for transmit and one for receive. The AC97 peripheral uses six DMA channels (three transmit and three receive) to allow different sample frequency data queues to be handled with low software overheads. The DMA Controller does not support memory to memory transfers. USB Device The features of the USB are: The AC97 Advanced Audio Codec controller includes a 5-pin serial interface to an external audio codec. The AC97 LINK is a bi-directional, fixed rate, serial Pulse Code Modulation (PCM) digital stream, dividing each audio frame into 12 outgoing and 12 incoming data streams (slots), each with 20-bit sample resolution. The AC97 controller contains logic that controls the AC97 link to the Audio Codec and an interface to the AMBA APB. Its main features include: • Serial-to-parallel conversion for data received from the external codec • Parallel-to-serial conversion for data transmitted to the external codec • Reception/Transmission of control and status information via the AMBA APB interface • Supports up to 4 different codec sampling rates at a time with its 4 transmit and 4 receive channels. The transmit and receive paths are buffered with internal FIFO memories, allowing data to be stored independently in both transmit and receive modes. The outgoing data for the FIFOs can be written via either the APB interface or with DMA channels 1 - 3. • Fully compliant to USB 1.1 specification • Provides a high level interface that shields the firmware from USB protocol details • Compatible with both OpenHCI and Intel’s UHCI standards • Supports full-speed (12 Mbps) functions • Supports Suspend and Resume signalling. 26 Rev. 02 — 19 March 2009 Product data sheet 32-Bit System-on-Chip NXP Semiconductors Audio Codec Interface (ACI) The ACI provides: • A digital serial interface to an off-chip 8-bit CODEC • All the necessary clocks and timing pulses to perform serialization or de-serialization of the data stream to or from the CODEC device. The interface supports full duplex operation and the transmit and receive paths are buffered with internal FIFO memories allowing up to 16 bytes to be stored independently in both transmit and receive modes. The ACI includes a programmable frequency divider that generates a common transmit and receive bit clock output from the on-chip ACI clock input (ACICLK). Transmit data values are output synchronous with the rising edge of the bit clock output. Receive data values are sampled on the falling edge of the bit clock output. The start of a data frame is indicated by a synchronization output signal that is synchronous with the bit clock. LH7A400 The transmit and receive paths are buffered with internal FIFO memories allowing up to 16 bytes to be stored independently in both transmit and receive modes. The UART can generate: • Four individually maskable interrupts from the receive, transmit and modem status logic blocks • A single combined interrupt so that the output is asserted if any of the individual interrupts are asserted and unmasked. If a framing, parity, or break error occurs during reception, the appropriate error bit is set, and is stored in the FIFO. If an overrun condition occurs, the overrun register bit is set immediately and the FIFO data is prevented from being overwritten. UART1 also supports IrDA 1.0 (15.2 kbit/s). The modem status input signals Clear to Send (CTS), Data Carrier Detect (DCD) and Data Set Ready (DSR) are supported on UART2 and UART3. Synchronous Serial Port (SSP) Timers The LH7A400 SSP is a master-only interface for synchronous serial communication with device peripheral devices that has either Motorola SPI, National Semiconductor MICROWIRE or Texas Instruments Synchronous Serial Interfaces. Two identical timers are integrated in the LH7A400. Each of these timers has an associated 16-bit read/write data register and a control register. Each timer is loaded with the value written to the data register immediately, this value will then be decremented on the next active clock edge to arrive after the write. When the timer underflows, it will immediately assert its appropriate interrupt. The timers can be read at any time. The clock source and mode is selectable by writing to various bits in the system control register. Clock sources are 508 kHz and 2 kHz. The LH7A400 SSP performs serial-to-parallel conversion on data received from a peripheral device. The transmit and receive paths are buffered with internal FIFO memories allowing up to eight 16-bit values to be stored independently in both transmit and receive modes. Serial data is transmitted on SSPTXD and received on SSPRXD. The LH7A400 SSP includes a programmable bit rate clock divider and prescaler to generate the serial output clock SCLK from the input clock SSPCLK. Bit rates are supported to 2 MHz and beyond, subject to choice of frequency for SSPCLK; the maximum bit rate will usually be determined by peripheral devices. UART/IrDA The LH7A400 contains three UARTs, UART1, UART2, and UART3. The UART performs: • Serial-to-Parallel conversion on data received from the peripheral device • Parallel-to-Serial conversion on data transmitted to the peripheral device. Product data sheet Timer 3 (TC3) has the same basic operation, but is clocked from a single 7.3728 MHz source. It has the same register arrangement as Timer 1 and Timer 2, providing a load, value, control and clear register. Once the timer has been enabled and is written to, unlike the Timer 1 and Timer 2, will decrement the timer on the next rising edge of the 7.3728 MHz clock after the data register has been updated. All the timers can operate in two modes, free running mode or pre-scale mode. FREE-RUNNING MODE In free-running mode, the timer will wrap around to 0xFFFF when it underflows and continue counting down. PRE-SCALE MODE In pre-scale (periodic) mode, the value written to each timer is automatically re-loaded when the timer underflows. This mode can be used to produce a programmable frequency to drive an external buzzer or generate a periodic interrupt. Rev. 02 — 19 March 2009 27 LH7A400 NXP Semiconductors Real Time Clock (RTC) 32-Bit System-on-Chip DC-to-DC Converter The RTC can be used to provide a basic alarm function or long time-base counter. This is achieved by generating an interrupt signal after counting for a programmed number of cycles of a real-time clock input. Counting in one second intervals is achieved by use of a 1 Hz clock input to the RTC. Battery Monitor Interface (BMI) The LH7A400 BMI is a serial communication interface specified for two types of Battery Monitors/Gas Gauges. The first type employs a single wire interface. The second interface employs a two-wire multi-master bus, the Smart Battery System Specification. If both interfaces are enabled at the same time, the Single Wire Interface will have priority. A brief overview of these two interface types are given here. The features of the DC-DC Converter interface are: • Dual drive PWM outputs, with independent closed loop feedback • Software programmable configuration of one of 8 output frequencies (each being a fixed divide of the input clock). • Software programmable configuration of duty cycle from 0 to 15/16, in intervals of 1/16. • Output polarity (for positive or negative voltage generation) is hardware-configured during power-on reset via the polarity select inputs • Each PWM output can be dynamically switched to one of a pair of preprogrammed frequency/duty cycle combinations via external pins. Watchdog Timer (WDT) SINGLE WIRE INTERFACE The Single Wire Interface performs: • Serial-to-parallel conversion on data received from the peripheral device • Parallel-to-serial conversion on data transmitted to the peripheral device • Data packet coding/decoding on data transfers (incorporating Start/Data/Stop data packets) The Single Wire interface uses a command-based protocol, in which the host initiates a data transfer by sending a WriteData/Command word to the Battery Monitor. This word will always contain the Command section, which tells the Single Wire Interface device the location for the current transaction. The most significant bit of the Command determines if the transaction is Read or Write. In the case of a Write transaction, then the word will also contain a WriteData section with the data to be written to the peripheral. SMART BATTERY INTERFACE The SMBus Interface performs: • Driven by the system clock • 16 programmable time-out periods: 216 through 231 clock cycles • Generates a system reset (resets LH7A400) or a FIQ Interrupt whenever a time-out period is reached • Software enable, lockout, and counter-reset mechanisms add security against inadvertent writes • Protection mechanism guards against interrupt-service-failure: – The first WDT time-out triggers FIQ and asserts nWDFIQ status flag – If FIQ service routine fails to clear nWDFIQ, then the next WDT time-out triggers a System Reset. General Purpose I/O (GPIO) • Serial-to-Parallel conversion on data received from the peripheral device • Parallel-to-Serial conversion of data transmitted to the peripheral device. The Smart Battery Interface uses a two-wire multimaster bus (the SMBus), meaning that more than one device capable of controlling the bus can be connected to it. A master device initiates a bus transfer and provides the clock signals. A slave device can receive data provided by the master or it can provide data to the master. Since more than one device may attempt to take control of the bus as a master, SMBus provides an arbitration mechanism, by relying on the wired-AND connection of all SMBus interfaces to the SMBus. 28 The Watchdog Timer provides hardware protection against malfunctions. It is a programmable timer that is reset by software at regular intervals. Failure to reset the timer will cause a FIQ interrupt. Failure to service the FIQ interrupt will then generate a System Reset. The WDT features are: The LH7A400 GPIO has eight ports, each with a data register and a data direction register. It also has added registers including Keyboard Scan, PINMUX, GPIO Interrupt Enable, INTYPE1/2, GPIOFEOI, and PGHCON. The data direction register determines whether a port is configured as an input or an output while the data register is used to read the value of the GPIO pins. The GPIO Interrupt Enable, INTYPE1/2, and GPIOFEOI registers are used to control edge-triggered Interrupts on Port F. The PINMUX register controls what signals are output of Port D and Port E when they are set as outputs, while the PGHCON controls the operations of Port G and H.

Figure 15 shows the timing for Activate a Bank and Write. SSP Waveforms The Synchronous Serial Port (SSP) supports three data frame formats: • Texas Instruments SSI • Motorola SPI • National Semiconductor MICROWIRE Figure 16 and Figure 17 show Texas Instruments synchronous serial frame format, Figure 18 through Figure 25 show the Motorola SPI format, and Figure 26 and Figure 27 show National Semiconductor’s MICROWIRE data frame format. For Texas Instruments SSI format, the SSPFRM pin is pulsed prior to each frame’s transmission for one serial clock period beginning at its rising edge. For this frame format, both the SSP and the external slave device drive their output data on the rising edge of the clock and latch data from the other device on the falling edge. See Figure 16 and Figure 17. Each frame format is between 4 and 16 bits in length, depending upon the programmed data size. Each data frame is transmitted beginning with the Most Significant Bit (MSB) i.e. ‘big endian’. For all three formats, the SSP serial clock is held LOW (inactive) while the SSP is idle. The SSP serial clock transitions only during active transmission of data. The SSPFRM signal marks the beginning and end of a frame. The SSPEN signal controls an off-chip line driver’s output enable pin.

Both the SSP and external slave device drive their output data on the falling edge of the clock, and latch data from the other device on the rising edge of the clock. Unlike the full-duplex transmission of the other two frame formats, the National Semiconductor MICROWIRE format utilizes a master-slave messaging technique that operates in half-duplex. When a frame begins in this mode, an 8-bit control message is transmitted to the off-chip slave. During this transmission no incoming data is received by the SSP. After the message has been sent, the external slave device decodes the message. After waiting one serial clock period after the last bit of the 8bit control message was received it responds by returning the requested data. The returned data can be 4 to 16 bits in length, making the total frame length between 13 to 25 bits. See Figure 26 and Figure 27.

AD-TFT and HR-TFT Vertical Timing Diagram CLOCK AND STATE CONTROLLER (CSC) WAVEFORMS Figure 42 shows the behavior of the LH7A400 when coming out of Reset or Power On. Figure 43 shows external reset timing, and Table 13 gives the timing parameters. Figure 44 depicts signal timing following a Reset. At Power-On, nPOR must be held LOW at least until the 32.768 kHz oscillator is stable, and must be deasserted at least two 32.768 kHz clock periods before the WAKEUP signal is asserted. Once the 14.7456 MHz oscillator is stable, the PLLs require 250 s to lock. On transition from Standby to Run (including a Cold Boot), the Wakeup pin must not be asserted for 2 seconds after assertion of nPOR to allow time for sampling BATOK and nEXTPWR. The delay prevents a false ‘battery good’ indication caused by alkaline battery recovery that can immediately follow a battery-low switch off. The battery sampling takes place on the rising edge of the 1 Hz clock. This clock is derived from the 32.768 kHz oscillator. The WAKEUP pin can be pulsed, but at least one edge must follow the 2 second delay to be recognized. For more information, see the application note “Implementing Auto-Wakeup on the LH7A4xx Series Devices” at www.nxp.com. Figure 45 shows the recommended components for the NXP LH7A400 32.768 kHz external oscillator circuit. Figure 46 shows the same for the 14.7456 MHz external oscillator circuit.

The switching speed of the CMOS circuitry within the SoC depends partly on Tj, and the lower the operating temperature, the faster the CMOS circuits will switch. Increased switching noise generated by faster switching circuits could affect the overall system stability. The amount of switching noise is directly affected by the application executed on the SoC. NXP recommends that users implementing a system to meet industrial temperature standards should use an external oscillator rather than a crystal to drive the system clock input of the System-on-Chip. This change from crystal to oscillator will increase the robustness (i.e., noise immunity of the clock input to the SoC). Printed Circuit Board Layout Practices LH7A400 POWER SUPPLY DECOUPLING The LH7A400 has separate power and ground pins for different internal circuitry sections. The VDD and VSS pins supply power to I/O buffers, while VDDC and VSSC supply power to the core logic, and VDDA/VSSA supply analog power to the PLLs. Each of the VDD and VDDC pins must be provided with a low impedance path to the corresponding board power supply. Likewise, the VSS, VSSA, and VSSC pins must be provided with a low impedance path to the board ground. Each power supply must be decoupled to ground using at least one 0.1 F high frequency capacitor located as close as possible to a VDDx, VSSx pin pair on each of the four sides of the chip. If room on the circuit board allows, add one 0.01 F high frequency capacitor near each VDDx, VSSx pair on the chip. To be effective, the capacitor leads and associated circuit board traces connecting to the chip VDDx, VSSx pins must be kept to less than half an inch (12.7 mm) per capacitor lead. There must be one bulk 10 F capacitor for each power supply placed near one side of the chip. RECOMMENDED PLL, VDDA, VSSA FILTER The VDDA pins supply power to the chip PLL circuitry. VSSA is the ground return path for the PLL circuit. NXP recommends a low-pass filter attached as shown in Figure 47. The values of the inductor and capacitors are not critical. The low-pass filter prevents high frequency noise from adversely affecting the PLL circuits. The distance from the IC pin to the high frequency capacitor should be as short as possible. 58 VDDC (SOURCE) VDDC LH7A400 10 µH VDDA + 22 µF 0.1 µF VSSA LH7A400-189 Figure 47. VDDA, VSSA Filter Circuit UNUSED INPUT SIGNAL CONDITIONING Floating input signals can cause excessive power consumption. Unused inputs without internal pull-up or pull-down resistors should be pulled up or down externally (NXP recommends tying HIGH), to tie the signal to its inactive state. 33 K or less is recommended. Some GPIO signals default to inputs. If the pins that carry these signals are unused, software can program these signals as outputs, eliminating the need for pullups or pull-downs. Power consumption may be higher than expected until software completes programming the GPIO. Some LH7A400 inputs have internal pullups or pull-downs. If unused, these inputs do not require external conditioning. OTHER CIRCUIT BOARD LAYOUT PRACTICES All outputs have fast rise and fall times. Printed circuit trace interconnection length must therefore be reduced to minimize overshoot, undershoot and reflections caused by transmission line effects of these fast output switching times. This recommendation particularly applies to the address and data buses. When considering capacitance, calculations must consider all device loads and capacitances due to the circuit board traces. Capacitance due to the traces will depend upon a number of factors, including the trace width, dielectric material the circuit board is made from and proximity to ground and power planes. Attention to power supply decoupling and printed circuit board layout becomes more critical in systems with higher capacitive loads. As these capacitive loads increase, transient currents in the power supply and ground return paths also increase.
