Flash Memory Reprogramming Kit by UART (M3A-2145G50) for M32R/ECU series

This product has been decided to discontinue selling.

The M3A-2145G50 connects the host PC's serial port to the M32R/ECU MCU serial I/O port on the evaluation board for starter kits and is a kit which realizes reprogramming control to the on-chip flash memory via direct UART communication with the flash reprogramming firmware which is stored in the M32R/ECU on-chip boot ROM. The M3S-UFLA32R is an on-chip flash memory reprogramming utility via UART communication and is built-in to the M3A-2145G50.
