Product details
Overview
STM32G473CCT3TR from STMicroelectronics is an Arm® Cortex®-M4 32-bit microcontroller with FPU, 512 KB Flash (ECC-enabled), 128 KB SRAM (including 32 KB CCM-SRAM with parity), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DAC channels, six rail-to-rail op-amps, and CORDIC/FMAC math accelerators - deployed in industrial motor control, digital power conversion, and precision sensor signal conditioning systems.
For engineers reviewing the STM32G473CCT3TR datasheet, STM32G473CCT3TR pinout, STM32G473CCT3TR application, or STM32G473CCT3TR equivalent, key selection criteria include its 170 MHz max CPU frequency, dual-bank Flash with read-while-write capability, 5 V-tolerant I/Os (up to 107 pins), FDCAN support for automotive-grade communication, and UCPD interface for USB Type-C™ power delivery control.
Technical Context
The STM32G473CCT3TR implements a tightly coupled Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator 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 dedicated hardware accelerators - CORDIC for real-time trigonometric computation and FMAC for high-speed digital filtering - alongside advanced analog subsystems: three buffered 1 MSPS DAC outputs, seven ultra-fast comparators, and six op-amps configurable in programmable-gain amplifier (PGA) mode with full terminal access.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431CBT6 | 256 KB Flash, 32 KB SRAM, no CORDIC/FMAC, single-bank Flash only | Suitable for cost-sensitive motor control without complex math or dual-bank update requirements | Select when application does not require hardware trigonometric acceleration or read-while-write firmware updates |
| STM32G483CET6 | 512 KB Flash, 128 KB SRAM, adds AES-256 crypto, PKE, and secure boot; same analog/peripheral set | Required for designs needing cryptographic authentication, secure firmware loading, or trusted execution environments | Choose when end-product mandates IEC 62443 compliance or secure bootloader validation |
Compared with STM32G431CBT6, the STM32G473CCT3TR delivers higher computational throughput and dual-bank Flash flexibility; versus STM32G483CET6, it omits cryptographic accelerators but maintains identical analog performance and math acceleration - making it optimal for non-secure, math-intensive industrial control.
