Product details
Overview
STM32G473CCU3TR 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 hardware math accelerators (CORDIC, FMAC). It operates up to 170 MHz (213 DMIPS) across 1.71–3.6 V and targets motor control, digital power conversion, and industrial sensing.
For engineers reviewing the STM32G473CCU3TR datasheet, STM32G473CCU3TR pinout, STM32G473CCU3TR application, or STM32G473CCU3TR equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, 5 V-tolerant GPIOs, FDCAN support for flexible data-rate automotive/industrial networks, and UCPD interface for USB Type-C™ power delivery systems.
Technical Context
The STM32G473CCU3TR implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals via multiple AHB/APB buses.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), a dedicated USB Type-C™/Power Delivery controller (UCPD), and advanced timer subsystems-including three 16-bit advanced motor control timers with dead-time generation and emergency stop-optimized for real-time closed-loop control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | LQFP64 package; adds AES-256 crypto accelerator and RNG; same core/peripherals but larger memory footprint (512 KB Flash, 128 KB SRAM) | Better suited for secure firmware updates and encrypted communications; requires larger PCB area | Select when cryptographic services or additional GPIOs are required; not pin-compatible |
| STM32G431CBU3 | UFQFPN48 package; reduced resources: 128 KB Flash, 32 KB SRAM, 3 ADCs, no CORDIC/FMAC, no UCPD | Targeted at cost-sensitive motor control or basic analog acquisition where math acceleration is unnecessary | Select for simplified BOM and lower unit cost; retains identical footprint and core architecture |

FAQ
What is the maximum operating frequency and corresponding performance metric?
The STM32G473CCU3TR achieves a maximum CPU frequency of 170 MHz, delivering 213 DMIPS (Dhrystone MIPS) with the ART Accelerator enabled. This performance level is sustained under full 0-wait-state Flash execution and includes DSP instruction support for efficient signal processing tasks.
Does this MCU support USB Type-C™ Power Delivery natively?
Yes-the STM32G473CCU3TR integrates a dedicated USB Type-C™/Power Delivery controller (UCPD) with CC line monitoring, VCONN switching, and PD policy engine. It eliminates the need for an external PD controller and supports USB-C port management including power role swapping and voltage negotiation.
How many analog-to-digital converters does the STM32G473CCU3TR include, and what are their key capabilities?
The device integrates five independent 12-bit ADCs supporting up to 42 channels total, with 0.25 µs conversion time and hardware oversampling up to 16-bit resolution. Each ADC supports programmable sampling time, injected/conversion sequences, and analog watchdogs-enabling simultaneous multi-sensor acquisition in motor control and power monitoring.
What low-power modes are supported, and what is the lowest achievable current draw?
The STM32G473CCU3TR supports Sleep, Stop, Standby, and Shutdown modes. In Standby mode with RTC active and backup registers retained, typical current consumption is 0.8 µA at 25 °C. With VBAT supplied, RTC continues timekeeping and alarm generation while main domain remains fully powered down.
