FR Flash serial writing

Version 3

    Version: **

     

    Answer:

    Our MCU can be programmed with two serial, and CAN MCU can be programmed with further one serial. The detailed is as following.

    Writing time of PC Serial Programming

                                                

    Items Time Remarks
    PROGRAM+VERIFYApprox. 60sDevice: MB91F355A
        FLASH size: 512KB
        Target internal frequency: 12.5MHz

     

    (Note) The frequency of the crystal oscillator that can be specified for each type of microcontroller is limited.

     

    (Note) Regarding compatible microcontroller of PC serial writer, please contact Fujitsu.

     

    Program with FLASH serial via CAN

     

    To program with serial writer (e.g. YDC products) via CAN to FLASH MCU is supported.

     

    At first of all, boot program (possible to get from YDC) is needed to be programmed already to FLASH MCU, but it can be programmed to FLASH MCU via CAN by it.
