Product details

Flash and RAM — sizing the firmware budget

The 64 KB Flash is adequate for a single motor-control algorithm plus a USB stack, but leaves limited headroom for over-the-air update staging or a full RTOS footprint. The 20 KB SRAM supports moderate data buffering — enough for a CAN message queue or a small audio buffer — but designs with large frame buffers or extensive lookup tables should budget carefully.

ROHS3 compliant.

Peripheral set for mixed-signal control

On-chip peripherals include DMA, motor-control PWM, a temperature sensor, and a 10-channel 12-bit ADC — enough to close a current-loop or read multiple analog sensors without an external ADC.
