Product details
Overview
STM32G473CCT3 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, delivering 213 DMIPS at 170 MHz. It integrates 512 KB Flash (with ECC), 128 KB SRAM (including 32 KB CCM-SRAM with parity), and rich 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 motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473CCT3 datasheet, STM32G473CCT3 pinout, STM32G473CCT3 application, or STM32G473CCT3 equivalent, key selection criteria include its 48-pin UFQFPN package, 170 MHz real-time performance with zero-wait-state Flash execution, integrated USB Type-C™/PD controller (UCPD), triple FDCAN support for automotive-grade communication, and hardware-accelerated trigonometric and filtering operations.
Technical Context
The STM32G473CCT3 implements an Arm Cortex-M4 core with floating-point unit and DSP extensions, coupled with ST's Adaptive Real-Time (ART) Accelerator enabling deterministic 0-wait-state execution from Flash memory. Its interconnect matrix supports concurrent access to Flash, SRAM, and peripherals without bus contention.
It features three independent FDCAN controllers compliant with ISO 11898-1:2015 (FD mode up to 5 Mbps), a dedicated UCPD interface for USB Type-C™ power delivery negotiation, and dual-bank Flash with read-while-write capability for seamless firmware updates - all operating across 1.71–3.6 V supply range with hardware parity on critical SRAM blocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431KBT6 | Same G4 series, but 128 KB Flash, no CORDIC/FMAC, 32-pin LQFP package | Limited math acceleration and peripheral count - suitable for basic motor control without complex observer algorithms | Select when cost-sensitive designs require only essential analog and timer resources, and firmware size remains <128 KB. |
| STM32F303RET6 | Cortex-M4F core at 72 MHz, 512 KB Flash, no UCPD or FDCAN; legacy F3-series with lower analog integration | Lacks USB-C PD, FDCAN, and hardware math accelerators - requires external components for modern power delivery and high-speed CAN FD | Choose only for legacy migration where existing F3 firmware and toolchain reuse outweigh missing G4 features. |
Compared with STM32G431KBT6, the STM32G473CCT3 adds hardware math acceleration and triple FDCAN for next-gen motor and power systems; versus STM32F303RET6, it delivers 2.4× higher compute throughput, integrated USB-C PD, and enhanced analog subsystem - justifying upgrade for new designs targeting functional safety and protocol modernization.

FAQ
What is the maximum operating temperature range for STM32G473CCT3?
The STM32G473CCT3 is qualified for industrial temperature range: –40 °C to +85 °C ambient. Thermal characteristics are specified in DS12712 Rev 5 Section 6.11, with θJA = 42.5 °C/W for UFQFPN48 package. Derating applies above 70 °C ambient depending on PCB copper area and airflow.
Does STM32G473CCT3 support hardware encryption for secure boot?
Yes - it includes a true random number generator (RNG) compliant with NIST SP800-90B, CRC calculation unit for firmware image integrity, and securable memory areas with proprietary code readout protection (PCROP). Secure boot implementation requires external trusted execution environment (TEE) or custom bootloader leveraging these primitives.
Can the internal op-amps be used as programmable-gain amplifiers (PGAs)?
Yes - all six operational amplifiers support PGA mode with gain selectable from 1× to 40× using internal resistor networks. Each op-amp's non-inverting input, inverting input, and output are accessible on dedicated pins, enabling direct sensor interfacing and configurable signal conditioning without external components.
Is the STM32G473CCT3 pin-compatible with other STM32G4 variants in UFQFPN48?
No - while STM32G473CCT3 shares the UFQFPN48 package with some G4 devices (e.g., STM32G431CBT6), pinouts differ due to distinct peripheral mappings and feature sets. For example, UCPD and FDCAN signals occupy unique pins not present on lower-tier G4 parts; always verify against DS12712 Section 4.1 before substitution.
