Back to Know-How on Development for F²MC-16LX Family

1. Flash serial writing

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

Program with PC serial programming for using UART

FUJITSU PC Serial Programming (W/E)

Writing time of PC Serial Programming

Item	Time	Remarks
PROGRAM+VERIFY	Approx. 40s	Device: MB90F553A FLASH size: 128KB Target internal frequency: 16MHz

(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.
