Product details
Overview
STM32G473CCT6 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 operational amplifiers, and three FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473CCT6 datasheet, STM32G473CCT6 pinout, STM32G473CCT6 application, or STM32G473CCT6 equivalent, key selection considerations include its dual-bank Flash with PCROP security, CORDIC/FMAC math accelerators for real-time trigonometric and filtering operations, 5 V-tolerant GPIOs, and UCPD interface for USB Type-C™ power delivery control.
Technical Context
The STM32G473CCT6 implements an Arm Cortex-M4 core with hardware FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes 512 KB dual-bank Flash (ECC, PCROP, read-while-write), 96 KB SRAM with parity on first 32 KB, and 32 KB CCM SRAM with parity - all accessible via multi-AHB interconnect matrix.
Analog integration comprises five independent 12-bit ADCs (up to 42 channels, 0.25 µs conversion, 16-bit oversampling), seven 12-bit DACs (3 buffered external @ 1 MSPS, 4 unbuffered internal @ 15 MSPS), six rail-to-rail op-amps (all terminals accessible, PGA mode supported), and three ultra-fast comparators - tightly coupled with advanced timers for closed-loop control.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G473CCT6?
The STM32G473CCT6 operates at up to 170 MHz with an Arm Cortex-M4 core featuring FPU and DSP extensions, achieving 213 DMIPS (Dhrystone 2.1). This performance level is sustained via the ART Accelerator, which enables zero-wait-state execution from Flash memory under all operating conditions.
Does the STM32G473CCT6 support hardware-accelerated mathematical functions, and if so, what types?
Yes - it integrates two dedicated hardware accelerators: the CORDIC unit for trigonometric (sin/cos/tan), hyperbolic, logarithmic, and exponential functions; and the FMAC (Filter Mathematical Accelerator) for real-time FIR/IIR filter coefficient computation and convolution, offloading intensive math from the CPU.
How many analog-to-digital converters does the STM32G473CCT6 include, and what are their key resolution and speed specifications?
The device integrates five independent 12-bit ADCs with up to 42 input channels, 0.25 µs conversion time, and hardware oversampling support up to 16-bit effective resolution. Each ADC features separate trigger sources, DMA request generation, and calibration registers for precision measurement in motor current sensing and power monitoring.
Is the STM32G473CCT6 pin-compatible with other members of the STM32G4 family, and what package options share the same pinout?
No - the STM32G473CCT6 uses the LQFP48 (7 × 7 mm) package and is not pin-compatible with larger variants (e.g., LQFP64 or LQFP100). However, it shares identical pin mapping with other LQFP48-packaged G473x devices (e.g., STM32G473CBT6), differing only in Flash size and optional peripherals enabled by silicon configuration.
