MANUFACTURER PART RECORD

STM32G431KBT6

STM32G431KBT6 is an STMicroelectronics Cortex-M4 microcontroller with FPU, up to 170 MHz, 128 KB flash and 32 KB SRAM including 10 KB CCM SRAM. It integrates CORDIC and FMAC accelerators and TIM1/TIM8 motor-control timers; do not assume the HRTIM peripheral of other STM32G4 devices. KBT6 identifies LQFP-32 with a 7 × 7 mm body, −40°C to +85°C ambient grade and tray packing. Verify the voltage-scaling configuration, analog supplies and package pin mapping for the intended design. Reviewed against ST DS12589 Rev 6 and the exact-code product-table row.

Sourcing note

Confirm ordering suffix, package, temperature grade, programming and date-code requirements.

Before you request a quote

Check the actual G431 peripheral set
Do not transfer high-resolution timer claims from other STM32G4 devices. Confirm timer pin mapping, analog channels and firmware requirements for the 32-pin package before considering another G4 code.
Keep memory, temperature and packing explicit
The 10 KB CCM region is included in the 32 KB SRAM total, not additional memory. Confirm KBT6, tray labels and lot requirements before quotation; the temperature suffix is not a packing suffix.
