　　A CPU board for evaluating the function and performance of the RZ/A1H 324-pin BGA product

　　RTK772100BC00000BR is a CPU board to evaluate functions and performance of Renesas Electronics RISC microcomputer R7S72100 and to execute development and evaluation of its application software. The features of the R7S72100 CPU board are described below.

　　• The following external memories are generally included.

　　- NOR flash memory: 64MB×2 (16-bit bus connection)

　　- SDRAM: 64MB×2 (16-bit bus connection)

　　- Serial flash memory: 64MB×3

　　- EEPROM: 16KB×1

　　• Any of NOR flash memory, serial flash memory, SD controller on-chip NAND flash memory, and MMC controller on-chip NAND flash memory can be selected as a boot memory.

　　• A serial port connector (RS-232C or USB Mini-B), USB connectors, CAN connectors, SD card slot, MMC card slot, RCA connector for video input, and MOST I/F connector are generally included as the R7S72100 peripheral function interface.

　　• An audio CODEC is included to enable advance development of the audio system.

　　• The USB connectors generally include the series A receptacles. The board pattern enables the Mini-B receptacles to be implemented for the USB host/function module evaluation.

　　• A LAN connector is generally included to enable software development or evaluation using the Ethernet.

　　• Data bus, address bus and on-chip peripheral function pins of the R7S72100 are all connected to the expansion connectors to enable timing evaluation with the peripheral devices using measurement instrument, or development of expansion board for its application.

　　• The ARM JTAG 20 and the CoreSight 20 are mounted to connect with the R7S72100 user debug interface
