1.1 Introduction
The SH7264 CPU board and its optional boards are designed for evaluating the features and performance of the SH7264 Group
of Renesas Technology original microcomputers (MCUs), as well as for developing and evaluating application software for these
MCUs. Following are features of the SH7264 CPU board and optional boards.
1.1.1 SH7264 CPU board (Part number: M3A-HS64)
The M3A-HS64 comes standard with 4-MB NOR flash memory (16-bit bus width), 16-MB SDRAM (16-bit bus width), 256-MB
NAND flash memory (16-bit bus width) and 2-MB serial flash memory as its external memory. The M3A-HS64 has three boot
options;
• Boot from NOR flash memory
• Boot from NAND flash memory
• Boot from serial flash memory
The M3A-HS64 comes standard with an RS-232C connector and a USB connector as the SH7264 peripheral interfaces.
The USB connector on the M3A-HS64 is a Series-A receptacle. The wiring pattern on the M3A-HS64 allows for connecting a
Mini-B receptacle to evaluate the USB host and function modules.
The SH7264 data bus, address bus and internal peripheral pins are connected to expansion connectors on the M3A-HS64 to allow
for timing evaluation with peripherals using measurement instruments, and the development of the optional board according to
its application.
The Renesas Technology E10A-USB on-chip emulator (AUD trace enabled: 36-pin, AUB trace disabled: 14-pin) can be
connected to the M3A-HS64.
1.1.2 Optional board for audio (Part number: M3A-HS64G01)
The M3A-HS64G01 is an evaluation board suitable for advance development of the audio system, which comes standard with an
audio interface, CD deck interface and character LCD module connector.
Also, it comes with two channels of a D/A converter for audio output, and one channel of a D/A converter and an A/D converter
for audio input and output as its audio interfaces.
It also comes standard with an LCD module interface connector, a UART interface connector, a CAN (Controller Area Network)
TM
connector, an IEBus
connector, an IIC connector, and an SD card connector.
1.1.3 Optional board for graphic display (Part number: M3A-HS64G02)
The M3A-HS64G02 is an evaluation board, which comes standard with a video input interface, an audio interface and an LCD
module interface for developing the video processing or music-playing applications.
All PWM output pins and timer output pins are inserted into connectors to allow for developing the automotive meter or
brightness-control applications.
It comes standard with a CAN connector, an IEBus
