The 80 MHz core with hardware FPU handles control loops with headroom for stack and communications. The 12-channel 12-bit ADC can sample three phase currents simultaneously. ## Memory map and field-reprogramming 256 KB of Flash (256K x 8) supports a bootloader plus application image; the 32 KB SRAM (32K x 8) supports a real-time OS with buffers for CAN message queues.
