STM32G431CBT6

STM32G431CBT6 is an STMicroelectronics STM32G4 access-line microcontroller in LQFP-48 — Arm Cortex-M4 with FPU at up to 170 MHz, 128 KB Flash and 32 KB SRAM including 10 KB CCM SRAM, running from 1.71 to 3.6 V at -40 to +85 °C. The selection point is the mixed-signal density for motor control and digital power in a 48-pin package: two fast 12-bit ADCs, four comparators, three op amps, four DAC channels, CORDIC and FMAC math accelerators, TIM1/TIM8 motor-control timers, FDCAN and USB — analog that would otherwise need external chips around a generic MCU. Selection advice: CBT6 is the LQFP-48 ordering code — choose it over the LQFP-32 STM32G431KBT6 on this site when the design needs the extra I/O and ADC channels; note the G431 does not include the HRTIM of the larger G474, so confirm the timer set against your control loop before layout. ST lists the STM32G431CBT6 as Active; parameters verified against ST datasheet DS12589 and the ST product page.
