Product details
Overview
STM32G474CET6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 96 KB SRAM (32 KB with hardware parity), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six rail-to-rail op-amps, and a 184-ps resolution HRTIM - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G474CET6 datasheet, STM32G474CET6 pinout, STM32G474CET6 application, or STM32G474CET6 equivalent, key selection considerations include its dual-bank read-while-write Flash architecture, CORDIC/FMAC math accelerators, FDCAN FD support, UCPD interface for USB Type-C™ PD, and LQFP48 package compatibility with legacy STM32G4 footprint designs.
Technical Context
The STM32G474CET6 implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and dual-bank Flash supporting seamless firmware updates. Its interconnect matrix routes up to 107 GPIOs across multiple AHB/APB buses with configurable DMA request mapping.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), a dedicated USB Type-C™/PD controller (UCPD), and a high-resolution timer (HRTIM) with six 16-bit counters and 184-ps timing resolution - optimized for complex PWM waveform generation in resonant LLC and PFC topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance mixed-signal microcontroller applications.

|---|---|---|---|
| STM32G474RET6 | Same core/peripherals, but 64-pin LQFP package with additional GPIOs, ADC channels, and communication interfaces | Required when >48 I/Os, >5 ADC inputs, or extra UART/SPI instances are needed | Select for expanded peripheral count and routing flexibility; not pin-compatible with LQFP48 |
| STM32G431CBT6 | Same G4 architecture but reduced feature set: 128 KB Flash, single 12-bit ADC, no HRTIM, no UCPD, no CORDIC/FMAC | Suitable for cost-sensitive motor control or basic digital power where ultra-high resolution timing or USB-C PD is unnecessary | Choose for lower BOM cost and smaller footprint where advanced analog/math features are unused |
Compared with STM32G474RET6, the STM32G474CET6 trades I/O count and peripheral density for compact LQFP48 packaging and lower system-level routing complexity; versus STM32G431CBT6, it delivers deterministic high-resolution timing, hardware-accelerated math, and USB-C PD capability essential for next-generation power electronics.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G474CET6?
The STM32G474CET6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS). This is achieved using the ART Accelerator for zero-wait-state Flash execution and includes full DSP instruction support and a single-precision FPU for floating-point operations - validated per ARM's standard Dhrystone benchmark methodology.
Does the STM32G474CET6 support USB Type-C™ Power Delivery, and how is it implemented?
Yes - the STM32G474CET6 integrates a dedicated USB Type-C™/Power Delivery controller (UCPD) compliant with USB PD 3.0. It handles CC line detection, VCONN power switching, PD message encoding/decoding, and role swap negotiation entirely in hardware, eliminating the need for an external PD controller and reducing system latency and BOM count.
How many analog-to-digital converters does the STM32G474CET6 include, and what are their key timing specifications?
The device includes five independent 12-bit ADCs supporting up to 42 total channels. Each ADC achieves 0.25 µs conversion time (4 MSPS), with hardware oversampling enabling up to 16-bit effective resolution. All ADCs support simultaneous sampling, injected/conversion sequences, and flexible trigger sources including HRTIM and timers.
Is the STM32G474CET6 pin-compatible with other STM32G4 variants, and what package options share the same footprint?
The STM32G474CET6 in LQFP48 is pin-compatible with all other STM32G4x4xx variants in the same LQFP48 package (e.g., STM32G431CBT6, STM32G441CBT6), sharing identical pin assignments for power, reset, clocks, and primary peripherals. However, feature availability (e.g., HRTIM, UCPD, CORDIC) varies by part number and must be verified per datasheet.
