The Mindmotion MM32F5270 and MM32F5280 microcontroller is based on ARM®STAR-MC1 processor. Built-in
L1 ICache, DCache, instruction tightly coupled memory ITCM and data tightly coupled memory DTCM,
with high performance and low power consumption.
Internal Flash
256 Kb (MM32F5270 and MM32F5280)
QSPI Flash
Up to 256Mb external QSPI Flash (MM32F5270)
Up to 2048Kb internal QSPI Flash (MM32F5280)
Supported Regions
Internal Flash 0x0800 0000 - 0x0803 FFFF
External QSPI Flash starting at 0x9000 0000 (End is defined by QSPI flash Size)
For now, the J-Link supports only this sections and MM32F5270 Family.
Reset
The device uses normal reset, no special handling necessary.
