Writing Flash Memory in FR Family FR81S MCUs - KBA218673

Version: **

Translation - Japanese: FRファミリFR81S MCUのFlashメモリへの書込み — KBA218673 - Community Translated (JA)

Question:

How do you write flash memory in the FR81S MCUs?

Answer:

The FR Family FR81S MCUs can be programmed with two serial writers; CAN MCUs can be programmed with one serial writer.

  1. Programming with Flash serial writer using SIO

  2. Programming with PC serial writer using UART

      Notes:
    • The frequency of the crystal oscillator that can be specified for each type of microcontroller is limited.
    • For information on microcontrollers compatible with the PC serial writer, contact Cypress Technical Support.
  3. Programming with Flash serial writer via CAN

    When programming with a serial writer (such as Yokogawa Digital Computer Corporation (YDC) products) via CAN to Flash MCU, a boot program (from YDC) needs to be programmed to the Flash MCU; this is also possible using CAN.
