(FCU firmware) What is On-chip ROM in the memory map diagram in the manual?

Latest Updated:01/23/2014


What is "On-chip ROM (FCU firmware) (read only)" in the memory map diagram in the manual?


It is the area where the dedicated firmware (FCU firmware) that programs the ROM (flash memory for code storage) and E2 DataFlash (flash memory for data storage) is stored.

To perform programming of the on-chip flash memory, FCU firmware must first be transferred from the "on-chip ROM (FCU firmware)" to the FCU-RAM area in advance.

For details, please see the Flash Memory chapter of the User's Manual: Hardware.
