170 MHz Cortex-M4F with HRTIM — the mixed-signal control ceiling
The STM32G474VEH6 runs an ARM Cortex-M4F core at 170 MHz — this is the throughput ceiling for the high-resolution timer (HRTIM) and the 12-bit ADC array. The 512 KB flash and 128 KB SRAM leave headroom for a dual-motor firmware stack with the HRTIM interrupt service routine and the math library for the CORDIC and FMAC accelerators.
42-channel ADC and 7-channel DAC — analog front-end density
The data converter block lists A/D 42x12b and D/A 7x12b — 42 analog input channels on a single 12-bit SAR ADC core with hardware oversampling, and seven 12-bit DAC outputs. For a multi-sensor acquisition board (current sense, position encoder, temperature), the channel count eliminates the need for an external multiplexer on the analog front-end. The 100-TFBGA package (8x8 mm) places the 86 I/O and the analog pins on a 0.50 mm pitch ball grid.
