STM32G474RET6

STM32G474RET6 is a mainstream Arm Cortex-M4 microcontroller from STMicroelectronics running at 170 MHz with 512 KB dual-bank Flash and 128 KB SRAM in a 64-pin LQFP package, with CORDIC trigonometric and FMAC filter math accelerators, a 184 ps-resolution high-resolution timer, five 12-bit ADCs, seven DAC channels, six op-amps and seven comparators. The analog density plus the HRTIM is the selection point: the 184 ps PWM resolution and hardware math accelerators let digital power supplies, motor drives and lighting controllers hit their control-loop targets with fewer external parts and less firmware load - the reason ST built the B-G474E-DPOW1 digital-power Discovery kit around exactly this part. Selection advice: the E density code (512 KB) sits above the 128/256 KB B/C variants in the STM32G4 line; the R6 code denotes LQFP-64, so confirm your I/O and peripheral needs against the datasheet pinout - not every peripheral instance of the larger packages is pinned out on the 64-pin device.
