STMicroelectronics STM32G484CET6

Overview

STM32G484CET6 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 (32 KB with hardware parity), and integrated CORDIC/FMAC math accelerators. It delivers 184 ps resolution on its HRTIM for precision motor control in industrial inverters.

For engineers reviewing the STM32G484CET6 datasheet, STM32G484CET6 pinout, STM32G484CET6 application, or STM32G484CET6 equivalent, key selection criteria include its dual-bank Flash with read-while-write capability, 5×12-bit ADCs (0.25 µs conversion), 7×12-bit DACs, FDCAN support, and UCPD interface for USB Type-C power delivery systems.

Technical Context

The device implements an Adaptive Real-Time Accelerator (ART) enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) for secure task isolation. Its interconnect matrix routes up to 107 GPIOs-including 5 V-tolerant pins-to multiple peripherals without contention.

It integrates three FDCAN controllers supporting flexible data-rate (CAN FD), a dedicated USB Type-C™/Power Delivery controller (UCPD), and a high-resolution timer (HRTIM) with six 16-bit counters and 184 ps timing resolution-enabling sub-microsecond PWM dead-time control in digital power supplies.

Key Specifications

Pinout & Package

STM32G484CET6 is packaged in LQFP48 (7 × 7 mm, 0.5 mm pitch), with 48 pins including 42 general-purpose I/Os (38 of which are 5 V tolerant), VDD/VSS power rails, VREF+/VREF– for ADC reference, and dedicated UCPD/USB/RTC/oscillator pins.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32G484CET6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone 2.1). This is achieved using the ART Accelerator for zero-wait-state Flash execution and includes full DSP instruction support and single-cycle MAC operations enabled by the Cortex-M4 FPU.

Does this MCU support USB Type-C™ Power Delivery without external components?

Yes-the STM32G484CET6 integrates a dedicated USB Type-C™/Power Delivery controller (UCPD) with hardware state machines for PD communication, CC line monitoring, VCONN switching, and BMC decoding. No external PD controller IC is required for basic sink/source implementations compliant with USB PD 3.0.

How many ADC channels are available, and what is their maximum sampling rate?

The device features five independent 12-bit ADCs supporting up to 42 total channels. Each ADC achieves 0.25 µs conversion time (4 MSPS), with hardware oversampling enabling effective resolutions up to 16 bits. Synchronized triggering across multiple ADCs allows simultaneous sampling for three-phase current/voltage acquisition.

What packaging and pin count does the 'CET6' suffix indicate?

The 'CET6' suffix denotes the LQFP48 package: 48-pin Low-Profile Quad Flat Package (7 × 7 mm body, 0.5 mm pitch), with exposed thermal pad. This variant provides 42 GPIOs (including 38 5 V-tolerant), full peripheral access, and compatibility with standard PCB assembly processes used in industrial control modules.
