Product details
Overview
STM32G474CCT6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 96 KB SRAM (including 32 KB CCM with parity), and integrated analog peripherals including six operational amplifiers, seven 12-bit DACs, five 12-bit ADCs (0.25 µs conversion), and a 184-ps-resolution HRTIM - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G474CCT6TR datasheet, STM32G474CCT6TR pinout, STM32G474CCT6TR application, or STM32G474CCT6TR equivalent, key selection criteria include HRTIM timing resolution for PWM generation, dual-bank Flash with read-while-write for firmware updates, CORDIC/FMAC hardware accelerators for real-time math, and UCPD support for USB Type-C™ power delivery control.
Technical Context
The STM32G474CCT6TR implements an adaptive real-time memory accelerator (ART Accelerator) enabling zero-wait-state execution from Flash at 170 MHz, paired with a Memory Protection Unit (MPU) for secure task isolation. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses to support concurrent high-bandwidth peripheral access.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 for flexible data-rate automotive and industrial networking, alongside a dedicated USB Type-C™/Power Delivery controller (UCPD) with VBUS monitoring and role swap logic - all synchronized via a multi-source clock system including 4–48 MHz crystal oscillator, 32 kHz RTC calibratable oscillator, and ±1% internal 16 MHz RC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | LQFP64 package (10 × 10 mm), 512 KB Flash, same peripherals - adds 16 more GPIOs and 2 extra ADC channels. | Better suited for designs requiring expanded I/O routing or additional analog inputs (e.g., multi-axis motion control). | Select when board layout allows larger footprint and higher pin count is needed for signal expansion or redundancy. |
| STM32H743VIT6 | Cortex-M7 core @ 480 MHz, 2 MB Flash, 1 MB SRAM, no HRTIM - adds DSI, Ethernet, and dual-core capability but lacks 184 ps timer. | Targeted at high-throughput HMI or gateway applications where real-time analog control is secondary to processing bandwidth. | Choose only if application demands >200 MHz CPU performance and can accept trade-offs in analog timing precision and power efficiency. |
Compared with STM32G474CCT6TR, the STM32G474RET6 offers pin-compatible scalability in larger packages, while the STM32H743VIT6 shifts focus from ultra-precise analog control to raw compute throughput - making the G474CCT6TR optimal for cost-constrained, timing-critical embedded power systems.

Does the STM32G474CCT6TR support true hardware-based USB Type-C™ Power Delivery negotiation?
Yes - the device integrates a dedicated USB Type-C™/Power Delivery controller (UCPD) with full BMC physical layer compliance, hardware CRC generation/checking, VBUS discharge control, and policy engine support for Source/Sink/RP roles. It handles PD 3.0 message exchange without CPU intervention, enabling certified 100 W power contracts in sink-mode applications.
How many independent 12-bit DAC channels does the STM32G474CCT6TR provide, and what are their output configurations?
The STM32G474CCT6TR provides seven independent 12-bit DAC channels: three buffered external outputs capable of 1 MSPS drive into 5 kΩ loads, and four unbuffered internal outputs rated for 15 MSPS - used for internal signal injection, reference generation, or fast feedback path modulation within the analog subsystem.
What is the resolution and timing precision of the High-Resolution Timer (HRTIM) in the STM32G474CCT6TR?
The HRTIM delivers 184 ps timing resolution across six 16-bit counters, enabling sub-nanosecond PWM edge placement. It supports 12 complementary PWM outputs with programmable dead time (down to 184 ps steps), fault input synchronization, and emergency stop - validated per DS12288 Rev 6 Section 5.3.16 for use in GaN/SiC gate driving and resonant converter topologies.
