CPU CPU board part number Memory CPU mounting
SH726B R0K5726B0C000BR
  • SDRAM (16 MB)
  • Serial flash memory (16 MB) × 2




  • Serial flash memory can be used as boot memory.
  • A serial port (RS-232C) connector, USB connectors, a CAN connector, and an SD card slot as standard peripheral function interfaces for the SH726B.
  • Audio DAC, audio codecs, and other audio interfaces, a CD deck interface, and a character LCD module connector 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.*1
  • A LAN connector is equipped as standard, and software development and evaluation using Ethernet is possible.
  • 16 key input switches (4 × 4 AD inputs) that can be used for user interface are installed as standard.
  • The pins of the built-in peripheral functions of the SH726B connect to Renesas Starter Kit (RSK)-specification common ring connectors and application headers, so users can perform timing evaluations with a peripheral device that uses a measurement device, or develop an expansion board for their development needs.
  • SH726B sample programs*2 and other software and tools necessary for advanced development of software are available.
  • An H-UDI connector (14-pin) is provided to connect the Renesas E10A-USB emulator*3.


*1. Only USB port 0 can be used as a USB function module. When using as the USB function module, use a commercially available connector converter for series A to B, or remove the series A receptacle and connect the Mini-B receptacle. (When connecting a Mini-B connector, it is also necessary to change the pull-up/down resistance.)
*2. Sample programs for microcontroller peripheral functions. (SPI multi-I/O bus controller, etc.)
*3. Sold separately.
