It features 64KB Flash, 12KB SRAM, and 4KB Core-Coupled Memory (CCM) RAM for zero-wait-state execution of time-critical routines. The High-Resolution Timer (HRTIM) with six 16-bit counters and 217ps resolution generates up to 10 independent PWM outputs for digital power conversion. The dual 12-bit ADCs sample at 5Msps. Three 12-bit DAC channels, three ultra-fast comparators, and one operational amplifier provide integrated analog signal conditioning. Communication includes CAN 2.0B, SPI, I2C, and up to three USARTs.","working_principle":"The Cortex-M4F core implements ARMv7E-M with DSP extensions and single-precision FPU for efficient control algorithm execution. The HRTIM uses a delay-locked loop (DLL) to subdivide the system clock by 32x for 217ps resolution at 72MHz. The six 16-bit counters support master-slave configurations with dead-time insertion and fault handling. The CCM RAM is on the CPU I-bus and D-bus, bypassing the bus matrix for deterministic zero-wait-state access. Dual ADCs support simultaneous, interleaved, or alternate trigger modes synchronized with timers.","pin_description":"
