M0519
6.4 Flash Memory Controller (FMC)
6.4.1 Overview
The NuMicro^® M0519 Series is equipped with 128/64 KB on-chip embedded flash for application
program memory (APROM) and data flash, and with 8K bytes for ISP loader program memory
(LDROM) that could be programmed boot loader to update APROM and data flash through In
System Programming (ISP) procedure. ISP function enables user to update embedded flash
when chip is soldered on PCB. After chip is powered on, Cortex^® -M0 CPU fetches code from
APROM or LDROM decided by boot select CBS (Config0[7:6]). By the way, the NuMicro^® M0519
Series also provides data flash for user to store some application dependent data before chip
power off. For 128 KB APROM device, the data flash is shared with original 128 KB program
memory and its start address is configurable in Config1. For 64 KB APROM device, the data flash
is fixed at 4K bytes.
