Chapter 1 Introduction Freescale Semiconductor, Inc... The DSP56852EVM is used to demonstrate the abilities of the DSP56852 and to provide a hardware tool allowing the development of applications that use the DSP56852. The DSP56852EVM is an evaluation module board that includes a DSP56852 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 DSP56852EVM is designed for the following purposes: • Allowing new users to become familiar with the features of the 56800E architecture. The tools and examples provided with the DSP56852EVM 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/Enhanced OnCE (EOnCE) port. The breakpoint features of the EOnCE 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 EOnCE 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 DSP's peripherals. The EOnCE port's unobtrusive design means that all memory on the board and on the DSP chip is available to the user. 1.1 DSP56852EVM Architecture The DSP56852EVM facilitates the evaluation of various features present in the DSP56852 part. The DSP56852EVM can be used to develop real-time software and hardware products based on the DSP56852.

SPI Serial EEPROM/Data FLASH Memory 2.3 SPI Serial EEPROM/Data FLASH Memory Freescale Semiconductor, Inc... A 1M-bit +3.3V SPI serial EEPROM/Data FLASH Memory, Atmel AT45DB011B-SC, is provided on the DSP56852EVM, reference Figure 2-3. This memory connects directly to the SPI Port through a header on the DSP56852. It can be used to load program code and data into the DSP56852’s internal or external memory spaces. Jumper block JG6 is provided to allow the user to disconnect the on-board SPI EEPROM/Data FLASH from the SPI port and allow him to connect his own SPI port peripheral. Since the SPI port and ISSI port are multiplexed on the DSP56852, the SPI port jumpers need to be removed to use the ISSI port. The header details are shown in Table 2-1.

Operating Mode Freescale Semiconductor, Inc... 2.5 Clock Source The DSP56852EVM uses a 4.00MHz crystal, Y1, connected to its External Crystal Inputs, EXTAL and XTAL. To achieve its 120MHz maximum operating frequency, the DSP56852 uses its internal PLL to multiply the input frequency by 30. An external oscillator source can be connected to the DSP by using the oscillator bypass connectors, JG3 and JG4; see Figure 2-5. If the input frequency is above 4MHz, then the EXTAL input should be jumpered to ground by adding a jumper between JG4 pins 1 and 2. The input frequency would then be injected on JG3’s pin 2. If the DSP needs to be synchronized to the codec’s sample frequency, then the DSP’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 DSP56852 JG4 3 2 EXTAL 1 4.00MHz JG3 1 2 3 12.2880MHz XTAL Figure 2-5.

An optional +5.0V DC power supply input is available through a 2-pin terminal block, TB1. A +12.0V DC 1.2A power supply is provided with the DSP56852EVM; however, less than 500mA is required by the EVM.

Stereo Codec Freescale Semiconductor, Inc... 2.12 Stereo Codec A 16-bit audio quality stereo codec, Crystal Semiconductor CS4218, is connected to the DSP56852’s ISSI 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 2-8. 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 ISSI port and allow him to connect his own codec to the ISSI port; see Figure 2-12. The on-board codec has analog signal conditioning logic, allowing direct connection to its line level input and line level output signals through two 1/8” stereo jacks; reference Figure 2-11. Table 2-8.

A National Semiconductor LM4880 provides the drive required for the use of headphones. This device offers a THD, which is superior by a factor of two to the CS4218’s on-chip headphone drive circuitry. The basic Analog codec connections are shown in Figure 2-11.

Codec Analog Connections 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 ISSI port, which is multiplexed with the SPI port, consists of independent transmitter and receiver sections and is used for serial communication with the codec. On the DSP side, the Serial Transmit Data pin, STXD, is an output when data is being transmitted to the codec. The Serial Receive Data pin, SRXD, is an input when data is being received from the codec. These two pins are connected to the codec’s Serial Data Input, SDIN, and Serial Data Output, SDOUT, pins. The DSP’s Transmit Serial Clock pin, STCK, provides the serial bit rate clock for the ISSI 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. The DSP’s GPIO PORT C Bit 4 pin, PC4, 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. This signal 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 2-12, Table 2-9 and Table 2-10. The codec’s MODE is set by the three MODE selection resistors, R66-R68. In the factory default setting of MODE 4, the codec is set to be the Master of the ISSI bus with its data word set at 32 bits per frame; i.e., 16 bits Left channel and 16 bits Right channel. The sample rate is selected on the Sample Rate Selector switch S4; see Table 2-8 for selection options. Codec control information is sent over a separate serial port using: PC5 as the Control Chip Select signal, CCS; PE0 as the Control Data Input signal, CDIN; and PE1 as the Control Clock signal, CCLK. 2-16 DSP56852EVM User’s Manual For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.
