Product details
Overview
STM32G473CET3TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash (ECC-enabled), 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six rail-to-rail op-amps, and CORDIC/FMAC math accelerators - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473CET3TR datasheet, STM32G473CET3TR pinout, STM32G473CET3TR application, or STM32G473CET3TR equivalent, key selection criteria include its 170 MHz CPU frequency with ART Accelerator, dual-bank Flash read-while-write capability, USB Type-C™/PD controller (UCPD), FDCAN support, and UFQFPN48 package compatibility for space-constrained designs.
Technical Context
The STM32G473CET3TR implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at up to 170 MHz (213 DMIPS). It integrates dual-bank Flash with ECC and PCROP, plus 96 KB main SRAM and 32 KB CCM-SRAM with parity - optimized for deterministic real-time control loops.
Analog subsystem includes 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 dedicated CORDIC/FMAC accelerators for trigonometric and filtering computations - all operating across 1.71–3.6 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431CBT6 | Same G4 series, but 128 KB Flash, no CORDIC/FMAC, fewer ADC/DAC channels, LQFP48 only | Suitable for cost-sensitive motor control where math acceleration and high-resolution analog I/O are not required | Select when full 512 KB Flash, dual-bank RWW, or hardware math engines are unnecessary - reduces cost by ~22% |
| STM32G474RET6 | LQFP64 package, 512 KB Flash, same peripherals, but adds AES-256/HASH crypto accelerators and higher-speed USB FS | Required for secure firmware updates, encrypted communications, or higher-bandwidth USB device applications | Choose when cryptographic security or expanded I/O count (64-pin vs 48-pin) justifies larger footprint and marginally higher cost |
Compared with STM32G431CBT6, the STM32G473CET3TR delivers 4× more Flash, hardware math acceleration, and richer analog integration - essential for complex real-time control.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G473CET3TR operates at up to 170 MHz using its Arm Cortex-M4 core with FPU. This yields 213 DMIPS (Dhrystone MIPS) performance, validated with ART Accelerator enabled for zero-wait-state Flash execution. Its 170 MHz rating is specified across the full industrial temperature range (–40°C to +85°C) and 1.71–3.6 V supply.
Does this MCU support true hardware-based USB Type-C™ power delivery?
Yes - the STM32G473CET3TR integrates a full USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0 specification. It includes the physical layer (PHY), protocol engine, and VCONN switch control, enabling standalone USB-C port negotiation without external PD controllers or level shifters.
How many ADC channels can be sampled simultaneously, and what is the fastest conversion time?
The device features five independent 12-bit ADCs capable of simultaneous sampling across up to 42 total channels. Each ADC achieves a minimum conversion time of 0.25 µs (4 MSPS), with hardware oversampling supporting effective resolutions up to 16 bits. Synchronized triggering ensures phase-aligned acquisition for multi-axis motor current sensing.
Is the UFQFPN48 package lead-free and RoHS-compliant?
Yes - the STM32G473CET3TR in UFQFPN48 package (part number suffix "TR") is fully RoHS-compliant and lead-free per EU Directive 2011/65/EU. It uses matte tin (Sn) termination finish and meets JEDEC J-STD-020 moisture sensitivity level MSL3, with peak reflow temperature of 260°C.
