The 56F827EVM is an evaluation module board that includes a 56F827 part, 16-bit stereo codec, external memory and a daughter card expansion interface. The daughter card expansion connectors are for signal monitoring and user feature expandability. The 56F827EVM is designed for the following purposes: • Allowing new users to become familiar with the features of the 56800 architecture. The tools and examples provided with the 56F827EVM facilitate evaluation of the feature set and the benefits of the family. • Serving as a platform for real-time software development. The tool suite enables the user to develop and simulate routines, download the software to on-chip or on-board RAM, run it, and debug it using a debugger via the JTAG/OnCETM port. The breakpoint features of the OnCE port enable the user to easily specify complex break conditions and to execute user-developed software at full-speed, until the break conditions are satisfied. The ability to examine and modify all user accessible registers, memory and peripherals through the OnCE port greatly facilitates the task of the developer. • Serving as a platform for hardware development. The hardware platform enables the user to connect external hardware peripherals. The on-board peripherals can be disabled, providing the user with the ability to reassign any and all of the controller's peripherals. The OnCE port's unobtrusive design means that all of the memory on the board and on the controller chip are available to the user. 1.1 56F827EVM Architecture The 56F827EVM facilitates the evaluation of various features present in the 56F827 part.

They can be found on this URL: www.freescale.com 56F827EVM User Manual, Rev. 2 2-2 Freescale Semiconductor Program and Data Memory 2.2 Program and Data Memory The 56F827EVM uses one bank of 128Ku16-bit Fast Static RAM (GSI GS72116, labelled U2) for external memory expansion; see the FSRAM schematic diagram in Figure 2-1. This physical memory bank is split into two logical memory banks of 64Kx16-bits: one for program memory and the other for data memory. By using the controller’s program strobe, PS, signal line along with the memory chip’s A0 signal line, half of the memory chip is selected when program memory accesses are requested and the other half of the memory chip is selected when data memory access are requested. This memory bank will operate with zero wait-state accesses while the 56F827 is running at 70MHz. However, when running at 80MHz, the memory bank operates with four wait-state accesses. This memory bank can be disabled by removing the jumper at JG3.

The 56F827 uses its internal PLL to multiply the input frequency by 20, achieving its 80MHz maximum operating frequency. An external oscillator source can be connected to the controller by using the oscillator bypass connectors, JG4 and JG5; see Figure 2-4. If the input frequency is above 4MHz, then the EXTAL input should be jumpered to ground by adding a jumper between JG4 pins 2 and 3. The input frequency would then be injected on JG5’s pin 2. If the controller needs to be synchronized to the codec’s sample frequency, then the controller’s input frequency should be jumpered using the 12.2280MHz codec frequency. If the input frequency is below 4MHz, then the input frequency can be injected on JG4’s pin 2. EXTERNAL OSCILLATOR HEADERS 56F827 JG4 3 2 1 4.00MHz EXTAL 10M JG5 1 2 12.2880MHz 3 XTAL Figure 2-4.

Schematic Diagram of the RESET Interface Technical Summary, Rev. 2 Freescale Semiconductor 2-13 2.11 Power Supply The main power input, +12.0V DC, to the 56F827EVM is through a 2.1mm coax power jack, P1. An optional +5.0V DC power supply input is available through a 2-pin terminal block, TB1. A 1.2A power supply is provided with the 56F827EVM; however, less than 500mA is required by the EVM. The remaining current is available for user daughter card applications when connected to the daughter card interface. The power regulation on the 56F827EVM provides +5.0V DC voltage regulation for the codec’s analog circuits and to the additional voltage regulation logic on the EVM. The additional voltage regulation logic provides +2.5V DC voltage regulation for the controller’s core and +3.3V DC voltage regulation for the controller’s I/O, memory, parallel JTAG interface and supporting logic; refer to Figure 2-9.

Schematic Diagram of the Power Supply 2.12 Stereo Codec A 16-bit audio quality stereo codec, Crystal Semiconductor CS4218, is connected to the 56F827’s SSI port to support audio, voice and signal analysis applications. The codec is clocked with a 12.288MHz oscillator. This allows the codec to operate between a sample frequency of 8kHz and 48kHz. The sample rate can be manually set by setting the appropriate switch positions on dip switch S4. The sample rate selections possible using this three-position dip switch are detailed in Table 2-7. The codec supports +3.3V digital levels, eliminating the need for voltage-level translation circuitry. Additionally, a set of zero ohm resistors are provided on the EVM to allow a user to disconnect the on-board codec from the SSI port and to connect his own codec to the SSI port; refer to Figure 2-11. The on-board codec has analog signal conditioning 56F827EVM User Manual, Rev. 2 2-14 Freescale Semiconductor Stereo Codec logic, allowing direct connection to its line-level input and line-level output signals through two 1/8” stereo jacks; see Figure 2-10.

CS4218 Stereo Audio Codec 2.12.1 Analog Input/Output The 56F827EVM uses jacks for line-level stereo input, line-level stereo output and stereo headphone output. A National Semiconductor LM4880 is used to provide the drive required for the use of headphones. This device offers a THD, which is superior to the CS4218’s on-chip headphone drive circuitry by a factor of two. The basic Analog codec connections are shown in Figure 2-10. 2.12.2 Digital Interface The serial interface of the codec transfers digital audio data and control data into and out of the device. The SSI port, which consists of independent transmitter and receiver sections, is used for serial communication with the codec. On the controller side, the Serial Transmit Data pin, STD, is an output when data is being transmitted to the codec. The Serial Receive Data pin, SRD, is an input when data is being received from the codec. These two pins are connected to the codec’s Serial Data Input pin, SDIN, and Serial Data Output pin, SDOUT. The controller’s Transmit Serial Clock pin, STCK, provides the serial bit rate clock for the SSI interface. It is connected to the codec’s Serial Port Clock pin, SCLK. Data is transmitted on the rising edge of SCLK and is received on the falling edge of SCLK. 56F827EVM User Manual, Rev. 2 2-16 Freescale Semiconductor Daughter Card Connectors The device’s GPIO PORT D Bit 0 pin, PD0, is programmed to control the codec’s Active Low Reset signal, RESET. The Serial Transmit Frame Sync pin, STFS, is programmed to control the codec’s Frame Sync signal, FSYNC. FSYNC is sampled by SCLK, with a rising edge indicating a new frame is about to start. The FSYNC frequency is always the system’s sample rate. It may be an input to the codec, or it may be an output from the codec in data mode. The basic codec digital connections are shown in Figure 2-11. The codec’s MODE is set by the three MODE selection resistors, R96-R98. In the factory default setting of MODE 4, the codec is set to be the Master of the SPI bus with its data word set at 32 bits per frame; i.e., a 16-bit Left channel and a 16-bit Right channel. The sample rate is selected on Sample Rate Selector switch S4; reference Table 2-7 for selection options. Codec control information is sent over a separate serial port using: PD1 as the Control Chip Select signal, CCS; PD2 as the Control Data Input signal, CDIN; and PD3 as the Control Clock signal, CCLK. 2.13 Daughter Card Connectors The EVM board contains two daughter card expansion connectors. One connector, J1, contains the controller’s external memory bus signals. The other connector, J2, contains the device’s peripheral port signals. 2.13.1 Memory Daughter Card Expansion Connector The controller’s external memory bus signals are connected to the Memory Daughter Card Expansion connector, J1.
