Features

  • NOR flash memory, serial flash memory, built-in NAND flash memory of the SD controller, or built-in NAND flash memory of the MMC controller can be selected as boot memory.
  • The board is equipped with a serial port (RS-232C or USB Mini-B) connector, USB connectors, CAN connectors, an SD card slot, an MMC card slot, Video input RCA connector, and a MOST I/F connector as standard peripheral function interfaces for the RZ/A1H.
  • The standard audio codecs are installed, so advanced development of an audio system is possible.
  • The USB connectors use the standard series A receptacle. The board pattern also allows for the mounting of a Mini-B receptacle for USB host/function module evaluation.
  • A LAN connector is equipped as standard, and software development and evaluation using Ethernet is possible.
  • The data bus, address bus, and pins for on-chip peripheral functions of the RZ/A1H are all connected to expansion connectors, allowing users to evaluate timing with a peripheral device that uses a measurement device, or develop an expansion board for their development needs.
  • A 20-pin ARM JTAG and a 20-pin CoreSight connector are provided for connecting to the RZ/A1H user debug interface.
