Program memory is 32 KB of Flash, backed by 32K x 8 SRAM — enough for a moderate application firmware plus a real-time OS tick and a few data buffers. ## Temperature range and package — what they tell you about deployment The exposed pad also provides a low-inductance ground return for the high-speed analog peripherals. With 11 channels of 12-bit ADC and four 12-bit DACs on-chip, you can close a current-sense and PWM loop without external converters — useful for a single-chip servo drive or a digitally controlled PSU. ## Lifecycle and sourcing posture For new designs, this is a safe selection from a lifecycle standpoint. As an independent distributor, we source this part against an RFQ. If you need a date-code trace or lot-level provenance for a quality audit, we can provide the chain of custody documentation.","metaTitle":"ST STM32G431K6U3 ARM Cortex-M4F MCU, 170 MHz, 32 KB Flash","metaDescription":"STM32G431K6U3 32-bit MCU from STMicroelectronics, ARM Cortex-M4F at 170 MHz, 32 KB Flash, 32K x 8 RAM, -40 to 125°C, 32-UFQFPN.
