Product details
Overview
STM32G473CEU6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, delivering 170 MHz/213 DMIPS performance, 512 KB Flash with ECC, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs), seven 12-bit DACs, six rail-to-rail op-amps, and three FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473CEU6 datasheet, STM32G473CEU6 pinout, STM32G473CEU6 application, or STM32G473CEU6 equivalent, key selection criteria include its 48-pin UFQFPN package, 170 MHz real-time execution with zero-wait-state Flash, hardware math accelerators (CORDIC + FMAC), dual-bank read-while-write Flash, and USB Type-C™/PD controller (UCPD) support for embedded power delivery applications.
Technical Context
The STM32G473CEU6 implements an Arm Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator enabling deterministic 0-wait-state execution from Flash at 170 MHz. Its memory subsystem includes dual-bank Flash with ECC and PCROP, plus 96 KB SRAM with parity on first 32 KB and 32 KB CCM-SRAM with parity for critical code/data.
Analog integration features five independent 12-bit ADCs (up to 42 channels, 0.25 µs conversion), seven 12-bit DACs (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six op-amps configurable as PGAs, and three ultra-fast rail-to-rail comparators - all supported by VREFBUF (2.048 V / 2.5 V / 2.9 V outputs) and dedicated analog supply (VDDA).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same core/peripherals but in LQFP64 package; adds 1 MB Flash, 256 KB SRAM, and enhanced cryptographic accelerators (AES, PKA) | Better suited for applications requiring larger code footprint, secure boot, or public-key cryptography (e.g., secure firmware updates) | Select when >512 KB Flash or hardware crypto acceleration is required; not pin-compatible with UFQFPN48 |
| STM32F303VCT6 | Lower-tier Cortex-M4 (72 MHz), no CORDIC/FMAC, 256 KB Flash, 48 KB SRAM, only 3× ADCs and 2× DACs, no UCPD | Targeted at cost-sensitive motor control or analog monitoring where 170 MHz or USB-C PD is unnecessary | Choose for legacy design migration or budget-constrained projects lacking math acceleration or USB-C requirements |
Compared with STM32G473CEU6, the STM32G474RET6 offers higher memory and security features at the cost of larger footprint and non-compatible packaging, while the STM32F303VCT6 sacrifices performance, analog density, and modern interfaces to reduce BOM cost and complexity.

FAQ
What is the maximum operating frequency and how is it achieved?
The STM32G473CEU6 achieves 170 MHz maximum CPU frequency using its Adaptive Real-Time (ART) Accelerator, which provides zero-wait-state execution from Flash memory. This eliminates instruction fetch stalls and ensures deterministic timing for real-time control loops, validated across the full industrial temperature range (–40 °C to +85 °C) and supply voltage (1.71–3.6 V).
Does STM32G473CEU6 support USB Power Delivery (USB-PD)?
Yes - it integrates a dedicated USB Type-C™/Power Delivery controller (UCPD) compliant with USB PD 3.0. The UCPD block handles physical layer signaling, BMC decoding/encoding, policy engine execution, and VBUS control without CPU intervention, enabling compact, certified USB-C power sink/source designs.
How many analog-to-digital converters does it have, and what are their key capabilities?
The device includes five independent 12-bit ADCs supporting up to 42 channels total, with 0.25 µs conversion time, hardware oversampling up to 16-bit resolution, and full 0–3.6 V input range. Each ADC supports injected/conversion sequences, analog watchdogs, and DMA-triggered transfers - optimized for multi-sensor synchronous sampling in motor control and power systems.
Is the UFQFPN48 package suitable for automated optical inspection (AOI) and reflow soldering?
Yes - the UFQFPN48 (7 × 7 mm, 0.5 mm pitch) package uses standard JEDEC MO-220 guidelines, with coplanar leads and exposed thermal pad compatible with industry-standard stencil printing, reflow profiles (J-STD-020), and AOI systems.
