The 64 KB Flash (64K x 8) is sized for a single application image plus a bootloader in moderate-complexity firmware — think a brushless DC motor controller or a Modbus sensor node. The 8 KB SRAM (8K x 8) is the tighter resource: DMA buffers, stack, and data arrays must fit within that ceiling. If your application needs dual-bank OTA or a large display frame buffer, this part will run out of RAM.
Peripherals and connectivity for distributed control
On-chip peripherals include DMA, a power-down reset (PDR), power-on reset (POR), programmable voltage detector (PVD), PWM timers, a temperature sensor, and a watchdog timer.
