NuMicro™ NUC100 Series equips with 128/64/32K bytes on chip embedded Flash for application
program memory (APROM) that can be updated through ISP procedure. In System Programming
(ISP) function enables 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, NuMicro™ NUC100 Series also provides additional DATA Flash for user, to
store some application dependent data before chip power off. For 128K bytes APROM device, the
data flash is shared with original 128K program memory and its start address is configurable and
defined by user application request in Config1. For 64K/32K bytes APROM device, the data flash
is fixed at 4K.
