For engineers reviewing the STM32G431C8T6TR datasheet, STM32G431C8T6TR pinout, STM32G431C8T6TR application, or STM32G431C8T6TR equivalent, key selection criteria include its 48-pin UFQFPN package, FDCAN support, 5 V-tolerant I/Os, hardware RNG, and UCPD interface for USB Type-C™ power delivery implementations.
Technical Context
The STM32G431C8T6TR implements an Arm Cortex-M4 core with single-precision FPU and Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash at 170 MHz. It integrates dual independent 16-bit advanced motor control timers (TIM1/TIM8) with dead-time generation, emergency stop, and up to 8 PWM channels - optimized for three-phase BLDC/PMSM drive control.
Analog subsystem includes two 16-bit ADCs (up to 23 channels, hardware oversampling), four rail-to-rail comparators, three fully accessible op-amps configurable as programmable gain amplifiers (PGA), and an internal voltage reference buffer (VREFBUF) with selectable 2.048 V / 2.5 V / 2.9 V outputs - supporting precision signal conditioning in closed-loop systems.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G431C8T6TR?
The STM32G431C8T6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone 2.1). This is achieved using the ART Accelerator, which enables zero-wait-state execution from Flash memory. The Cortex-M4 core includes a single-precision FPU and DSP instruction set, supporting floating-point math and signal processing workloads without software emulation overhead.
Does the STM32G431C8T6TR support USB Type-C™ Power Delivery, and what hardware blocks enable it?
Yes, the STM32G431C8T6TR integrates a full USB Type-C™ Power Delivery (UCPD) controller, including the physical layer (PHY), BMC encoder/decoder, and protocol engine. It supports USB PD 3.0 specification, VCONN switching, and role swapping. No external PD controller IC is required - the UCPD peripheral connects directly to CC1/CC2 pins and manages power contract negotiation autonomously.
How many analog-to-digital converters does the STM32G431C8T6TR include, and what are their key resolution and speed specifications?
The device integrates two independent 16-bit analog-to-digital converters (ADC1 and ADC2), each capable of 0.25 µs conversion time (up to 4 MSPS). Both support hardware oversampling to increase effective resolution (e.g., 16× oversampling yields >18-bit ENOB). Input range is 0 to VREF+ (up to 3.6 V), with up to 23 external channels and built-in temperature sensor/VREFINT monitoring.
What package type and pin count does the STM32G431C8T6TR use, and is it RoHS-compliant?
The STM32G431C8T6TR uses a 48-pin Ultra-Fine Pitch Quad Flat No-lead (UFQFPN) package measuring 7 × 7 mm with 0.5 mm pitch. It is lead-free and RoHS-compliant per EU Directive 2011/65/EU, and qualifies for industrial temperature range (–40 °C to +85 °C). The "TR" suffix indicates tape-and-reel packaging for automated assembly.
