66 / 107 page NUC100/120xxxDN Aug 31, 2015 Page 66 of 107 Rev 1.01 FLASH MEMORY CONTROLLER (FMC) 6.4 6.4.1 Overview The NuMicro ® NUC100 series has 128/64/32 Kbytes on-chip embedded Flash for application program memory (APROM) that can be updated through ISP procedure. The In-System- Programming (ISP) function enables user to update program memory 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) in Config0. By the way, the NuMicro ® NUC100 series also provides additional DATA Flash for user to store some application dependent data. For 128 Kbytes APROM device, the Data Flash is shared with original 128K program memory and its start address is configurable in Config1. For 64/32 Kbytes APROM device, the Data Flash is fixed at 4K. 6.4.2 Features Runs up to 50 MHz with zero wait state for continuous address read access All embedded flash memory supports 512 bytes page erase 128/64/32 KB application program memory (APROM) 4 KB In-System-Programming (ISP) loader program memory (LDROM) 4KB Data Flash for 64/32 KB APROM device Configurable Data Flash size for 128KB APROM device Configurable or fixed 4 KB Data Flash with 512 bytes page erase unit Supports In-Application-Programming (IAP) to switch code between APROM and LDROM without reset In-System-Programming (ISP) to update on-chip Flash |
