STMicroelectronics STM32G473RCT6TR

Overview

STM32G473RCT6TR 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, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DAC channels, six operational amplifiers, and three FDCAN controllers. It targets motor control, digital power conversion, and industrial sensing applications requiring real-time math acceleration and high-precision analog signal chain integration.

For engineers reviewing the STM32G473RCT6TR datasheet, STM32G473RCT6TR pinout, STM32G473RCT6TR application, or STM32G473RCT6TR equivalent, key selection criteria include its CORDIC/FMAC hardware accelerators for trigonometric and filtering operations, dual-bank Flash with read-while-write capability, 5 V-tolerant I/Os across 107 pins, and UCPD support for USB Type-C™ power delivery implementation.

Technical Context

The STM32G473RCT6TR implements an Arm Cortex-M4 core with floating-point unit and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes dual-bank 512 KB Flash with ECC and PCROP, plus 96 KB SRAM with parity on first 32 KB and 32 KB CCM SRAM with parity on instruction/data bus.

Analog integration centers on 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 rail-to-rail op-amps configurable as PGAs, and three ultra-fast comparators - all supported by internal VREFBUF (2.048 V / 2.5 V / 2.9 V outputs).

FAQ

What is the maximum operating frequency and associated performance metric of the STM32G473RCT6TR?

The STM32G473RCT6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), achieved through its Arm Cortex-M4 core with FPU and Adaptive Real-Time Accelerator enabling zero-wait-state execution from Flash memory. This frequency is sustained under full temperature and voltage range conditions as specified in DS12712 Rev 5, Section 5.3.1.

Does the STM32G473RCT6TR support hardware-accelerated mathematical functions, and if so, which ones?

Yes, it integrates two dedicated hardware accelerators: the CORDIC unit for trigonometric (sin/cos/tan/atan), hyperbolic, and square-root functions with latency under 100 ns; and the Filter Mathematical Accelerator (FMAC) for real-time FIR/IIR filtering, convolution, and matrix operations. Both operate independently of the CPU and are accessible via dedicated registers per RM0440 reference manual.

How many analog-to-digital converters does the STM32G473RCT6TR include, and what are their key specifications?

The device integrates five independent 12-bit ADCs, supporting up to 42 channels total with 0.25 µs conversion time. Each ADC supports hardware oversampling up to 16-bit resolution, programmable sampling time, and synchronous triggering. The conversion range is 0 to VREF+ (up to 3.6 V), and calibration is supported via factory-trimmed values stored in system memory (DS12712 Rev 5, Section 5.3.18).

What USB capabilities does the STM32G473RCT6TR provide, and is an external PHY required?

The STM32G473RCT6TR includes a full-speed USB 2.0 interface with integrated PHY, supporting device, host, and OTG roles. It also features USB Type-C™ Power Delivery (UCPD) controller logic with dedicated CC1/CC2 pins, BMC encoding/decoding, and VBUS monitoring - all implemented in hardware without external transceivers. LPM (Link Power Management) and BCD (Battery Charging Detection) are natively supported per Section 3.34 and 3.35 of DS12712 Rev 5.
