  • Includes three boot options, NOR flash memory, NAND flash memory, and serial flash memory
  • Comes standard with the USB Series-A receptacle for evaluating the SH7264 USB function, allowing advanced development and evaluation of the USB host module application(*1)
  • SH7264 data bus, address bus and on-chip peripheral pins are all connected to expansion connectors (or through-holes) on this board to allow for timing analysis with peripherals that use measurement instruments. Optional boards for audio (M3A-HS64G01) and graphic display (M3A-HS64G02) are also available.
  • Sample software provided with the SH7264 application notes can be used on this CPU board. Click here for the SH7262, SH7264 application notes.
  • H-UDI connectors (36-pin and 14-pin) are provided to connect the Renesas E10A-USB emulator.(*2)  

*1: When using the SH7264 USB module as the USB function module, use the commercially available connector converter for Series-A to B, or remove the Series-A receptacle and mount the mini-B receptacle.
*2: The E10A-USB emulator is not included with this product.

Regarding handling of former company name in content

Following the reorganization of design and development departments of Renesas affiliates in Japan dated August 1, 2014, the device solution development functions of Renesas Solutions Corp. (RSO) were transferred to Renesas System Design Co., Ltd. (RSD) and the name of the company to which the departments belong was also changed from RSO to RSD as of August 1, 2014.
Consequently, although the content (schematic circuit diagrams and bill of materials) that is provided on this page may include mention of the former company name, the content is still a valid Renesas document.
Your understanding is most appreciated.
