STMicroelectronics STM32G474CEU6

Overview

STM32G474CEU6 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 HRTIM with 184 ps resolution for precision motor control. It integrates CORDIC and FMAC hardware accelerators, dual-bank read-while-write Flash, and supports USB Full-Speed, FDCAN, and UCPD for USB Type-C power delivery applications.

For engineers reviewing the STM32G474CEU6 datasheet, STM32G474CEU6 pinout, STM32G474CEU6 application, or STM32G474CEU6 equivalent, key selection criteria include HRTIM timing resolution, analog subsystem capability (5×12-bit ADCs, 7×DACs, 6×OPAMPs), low-power mode behavior, and UFQFPN48 package compatibility with high-density PCB layouts.

Technical Context

The STM32G474CEU6 implements an Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and dual-bank Flash architecture supporting seamless firmware updates. Its interconnect matrix routes up to 107 GPIOs-including 5 V-tolerant pins-to multiple peripherals without contention.

It features three independent FDCAN controllers compliant with ISO 11898-1:2015 (FD), a dedicated USB Type-C™/Power Delivery controller (UCPD), and a high-resolution timer (HRTIM) with six 16-bit counters, 12 PWM outputs, and 184 ps timing resolution-enabling sub-nanosecond dead-time control in digital power converters.

FAQ

What is the maximum operating temperature range for STM32G474CEU6?

The STM32G474CEU6 is qualified for industrial temperature range: –40 °C to +85 °C ambient. Its thermal resistance (θ_JA) is 41.5 °C/W in the UFQFPN48 package, enabling reliable operation in enclosed enclosures with natural convection cooling up to 70 °C ambient without forced airflow.

Does STM32G474CEU6 support hardware encryption?

No, STM32G474CEU6 does not integrate AES, PKA, or hash accelerators. Those features are present only in the STM32G484xx and STM32G491xx variants. This part relies on software-based cryptography libraries if encryption is required, with no dedicated hardware acceleration.

Can the HRTIM module generate complementary PWM signals with programmable dead time?

Yes. The HRTIM includes dedicated dead-time insertion units per output channel, supporting programmable dead times from 0 to 255 × HRTIM clock period (184 ps resolution). It also provides fault protection inputs (EVDx) that can force immediate shutdown of PWM outputs during overcurrent or overtemperature events.

Is the UFQFPN48 package RoHS-compliant and lead-free?

Yes. The STM32G474CEU6 in UFQFPN48 packaging meets RoHS Directive 2011/65/EU and is lead-free (Pb-free), with matte tin (Sn) termination finish. Its moisture sensitivity level (MSL) is 3 per J-STD-020, requiring bake conditioning if exposed to ambient >30 °C/60% RH for >168 hours before reflow.
