M051 DN/DE
6.4 Flash Memory Controller (FMC)
6.4.1 Overview
The M05xxDN/DE are equipped with 64/32/16/8 Kbytes on chip embedded Flash memory for
application program (APROM) that can be updated through ISP registers. In-System-
Programming (ISP) and In-Application-Programming (IAP) enable user to update program
memory when chip is soldered on PCB. After chip power on Cortex^® -M0 CPU fetches code from
APROM or LDROM decided by boot select (CBS) in CONFIG0. By the way, the M05xxDN/DE
also provide additional 4 Kbytes DATA Flash for user to store some application depended data
before chip power off in 64/32/16/8 Kbytes APROM model.
The M05xxDN/DE provides more settings in CONFIG0 to support more advanced functions,
including power-on with tri-state I/O, default to enable WDT after booting, enable WDT in Power-
down mode, and IAP functions.
