Overview

This product is a CPU board for motor control equipped with RX26T. Motor control using RX26T can be easily realized by using it in combination with a supported inverter board. By using a supported communication board, the CPU board can be electrically isolated from the PC for safe motor control evaluation and debugging.

There are three types of MCB-RX26T: Type A, B, and C, each featuring a different MCU:

  • Type A: R5F526TFCDFP (100pin, ROM/RAM=512KB/64KB, without TSIP-Lite)
  • Type B: R5F526TFDDFP (100pin, ROM/RAM=512KB/64KB, with TSIP-Lite)
  • Type C: R5F526TACDFM (64pin, ROM/RAM=256KB/48KB, without TSIP-Lite)\

This product (MCB-RX26T Type B) has two versions: Version 1 (P/N: RTK0EMXE70C01000BJ) and Version 2 (P/N: RTK0EMXE70C01001BJ).

  • Version 1 does not support PFC control for the high-voltage inverter board, while Version 2  supports single PFC control and interleaved PFC control.
  • Version 1 will be discontinued. Please consider using the successor product, Version 2.

Please note that the supported board versions differ depending on the sample code. The supported boards are listed in the application notes included with the sample code. Be sure to use the sample code corresponding to your board's version.
