NUC472
6.4 Flash Memory Controller (FMC)
6.4.1 Overview
The NUC472 is equipped with 256/512 Kbytes on-chip embedded flash for application program
memory (APROM) and data flash that can be updated through ISP procedure. In-System-
Programming (ISP) and In-Application-Programming (IAP) enables user to update chip embedded
flash when chip is soldered on PCB. After chip is powered on, Cortex^® -M4 CPU fetches code from
APROM or LDROM decided by boot select (CBS) in Config0. By the way, the NUC472 also
provides Data Flash for user to store some application dependent data before chip is powered off.
The NUC472 supports another flexible feature: configurable data flash size. The data flash size is
decided by data flash enable (DFEN) in Config0 and data flash base address (DFBADR) in
Config1. When DFEN is set to 1, the data flash size is zero. When DFEN is set to 0, the APROM
and data flash share 256/512 Kbytes continuous address and the start address of data flash is
defined by (DFBADR) in Config1.
