Product details
Overview
STM32G473CCT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, 512 KB Flash (ECC), 128 KB SRAM (96 KB + 32 KB CCM), and 170 MHz max CPU frequency (213 DMIPS). It integrates dual-bank read-while-write Flash, CORDIC/FMAC math accelerators, 5×12-bit ADCs (42-channel, 0.25 µs), 7×DAC channels, 6 operational amplifiers, and 3 FDCAN controllers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G473CCT6TR datasheet, STM32G473CCT6TR pinout, STM32G473CCT6TR application, or STM32G473CCT6TR equivalent, key selection criteria include its 48-pin UFQFPN package, 1.71–3.6 V supply range, 5 V-tolerant I/Os, integrated USB FS + UCPD, and hardware-accelerated trigonometric/filter math for real-time control loops.
Technical Context
The STM32G473CCT6TR implements an Arm Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its memory subsystem includes dual-bank Flash with PCROP and ECC, plus 96 KB SRAM with parity on first 32 KB and 32 KB CCM-SRAM with parity - optimized for deterministic real-time code/data separation.
Analog integration features five independent 12-bit ADCs (up to 42 channels, hardware oversampling up to 16-bit), seven DAC channels (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 - all synchronized via shared trigger routing for multi-sensor acquisition and closed-loop feedback.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M4 with FPU and DSP instructions; enables floating-point math and signal processing without software emulation. |
| Max Clock Frequency | 170 MHz (213 DMIPS); supports high-bandwidth control loops and real-time audio/communication stacks. |
| Flash Memory | 512 KB with ECC, dual-bank read-while-write, PCROP, and 1 KB OTP; allows safe firmware updates and secure boot partitioning. |
| SRAM | 96 KB general-purpose + 32 KB CCM-SRAM (parity-checked); separates critical ISR/data buffers from main heap for reliability. |
| Analog Peripherals | 5×12-bit ADCs (0.25 µs, 42 ch), 7×DACs (3 ext @ 1 MSPS), 6 op-amps (PGA mode), 7 comparators; supports sensor fusion and analog front-end consolidation. |

Pinout & Package
STM32G473CCT6TR uses a 48-pin UFQFPN package (7 × 7 mm, 0.5 mm pitch), qualified for industrial temperature range (–40 °C to +85 °C) and RoHS-compliant. Pinout conforms to ST's standardized LQFP48/UFQFPN48 mapping with dedicated VDDA/VSSA, VREF+, VREF–, and VBAT pins for precision analog operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core power supply / ground | Dual VDD/VSS pairs decouple digital core; separate VDDA/VSSA required for analog stability. |
| VDDA, VSSA | Analog power supply / ground | Mandatory isolated analog domain; must be filtered and routed separately to minimize noise coupling into ADC/DAC/OPAMP. |
| VREF+, VREF– | ADC/DAC reference inputs | Accept external reference (0–3.6 V) or connect to internal VREFBUF; enables ratiometric or absolute voltage measurement. |
| VBAT | Backup power supply | Supplies RTC and backup registers during main power loss; supports coin-cell battery connection. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/O | Up to 107 fast I/Os; 5 V tolerant on selected pins (e.g., PA0–PA15, PB0–PB15, PC0–PC15); configurable as ADC/DAC/comp/OPAMP interfaces. |
| NRST | Active-low reset input | Asynchronous reset with internal pull-up; accepts external push-button or supervisor IC assertion. |
Key Features
| Feature | Design Value |
|---|---|
| CORDIC accelerator | Hardware trigonometric/logarithmic/exponential computation in ≤10 cycles - eliminates floating-point library overhead in field-oriented control. |
| FMAC unit | Configurable 32-bit filter engine supporting FIR/IIR with 128-tap capability - enables real-time digital filtering without DMA or CPU intervention. |
| Adaptive Real-Time Accelerator (ART) | Zero-wait-state Flash execution at 170 MHz - ensures deterministic interrupt latency and jitter-free PWM timing in motor drives. |
| Flexible analog subsystem | 6 op-amps (all pins accessible, PGA gain 1–16), 7 comparators, internal VREFBUF (2.048/2.5/2.9 V) - reduces external BOM for sensor signal conditioning. |
| FDCAN with flexible data-rate | Three independent FDCAN controllers supporting ISO 11898-1:2015; enables 2 Mbps data phase for high-resolution actuator feedback in automotive/industrial networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G431CBT6 | Same G4 series, but 128 KB Flash, 32 KB SRAM, no CORDIC/FMAC, single ADC bank, 2 FDCAN. | Suitable for cost-sensitive motor control where math acceleration and dual ADC banks are unnecessary. | Select when full 512 KB Flash and hardware math units are not required; lower BOM cost and smaller footprint. |
| STM32H743VIT6 | Higher-tier Cortex-M7, 2 MB Flash, 1 MB SRAM, dual-core option, no CORDIC/FMAC, different peripheral set (no UCPD). | Targeted at complex HMI + control co-processing; lacks integrated USB-C PD controller and analog math acceleration. | Choose for applications needing >170 MHz performance, large memory, or dual-core RTOS, but requires external PD IC and more PCB area. |
Compared with STM32G431CBT6, the STM32G473CCT6TR delivers 4× Flash, hardware math acceleration, and triple FDCAN - essential for high-fidelity motor control and USB-C PD integration. Versus STM32H743VIT6, it offers superior analog integration and dedicated UCPD at lower power and cost, though with less raw compute headroom.

FAQ
What is the maximum operating temperature range for STM32G473CCT6TR?
The STM32G473CCT6TR is rated for industrial temperature range: –40 °C to +85 °C ambient. This is confirmed in Section 5.3.1 of DS12712 Rev 5, and applies to all package variants including the UFQFPN48. Thermal derating is not required within this range under specified power dissipation limits.
Does STM32G473CCT6TR support USB Power Delivery communication natively?
Yes - it integrates a dedicated USB Type-C™ / USB Power Delivery controller (UCPD) compliant with USB PD 3.0 specification. The UCPD peripheral handles BMC physical layer, PD protocol stack execution, and VBUS monitoring without requiring external transceivers or policy engines.
How many independent ADC instances does STM32G473CCT6TR provide?
The device contains five independent 12-bit ADCs (ADC1–ADC5), each with up to 16 external channels and full hardware oversampling capability (up to 16-bit effective resolution). They share common clock and trigger resources but operate autonomously for concurrent multi-sensor acquisition.
Is the CORDIC unit accessible via standard CMSIS headers or only through HAL drivers?
The CORDIC peripheral is directly memory-mapped and fully accessible via CMSIS-Core register definitions (CORDIC_BASE, CORDIC_CR, CORDIC_SR, etc.). ST provides low-level CMSIS functions (e.g., HAL_CORDIC_Start_IT) but engineers may use bare-metal register access for deterministic latency-critical applications.
