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.
