STMicroelectronics STM32G484VET6

Overview

STM32G484VET6 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, 128 KB SRAM (96 KB + 32 KB CCM), and integrated analog peripherals including five 12-bit ADCs (0.25 µs conversion), seven 12-bit DACs, six rail-to-rail op-amps, and a high-resolution timer (HRTIM) with 184 ps resolution-used in precision motor control and digital power conversion systems.

For engineers reviewing the STM32G484VET6 datasheet, STM32G484VET6 pinout, STM32G484VET6 application, or STM32G484VET6 equivalent, key selection criteria include HRTIM timing precision, dual-bank Flash read-while-write capability, hardware math accelerators (CORDIC/FMAC), FDCAN FD support, and UCPD interface for USB Type-C™ power delivery implementations.

Technical Context

The STM32G484VET6 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) and DSP instruction set for deterministic real-time control. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses to support concurrent analog acquisition, PWM generation, and communication stack processing.

It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (FD mode), a dedicated USB Type-C™/PD controller (UCPD), and a 32-channel HRTIM with independent dead-time insertion and emergency stop-enabling synchronized multi-phase gate driving in industrial inverters and active rectifiers.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32G484VET6 achieves 170 MHz operation using its Adaptive Real-Time Accelerator (ART), which caches Flash instructions and data to eliminate wait states. This allows deterministic execution of real-time control algorithms without external SRAM or cache coherency overhead-verified under industrial temperature conditions with VDD = 3.3 V.

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

Yes-the integrated UCPD peripheral handles USB Type-C™ configuration channel (CC) line monitoring, PD message parsing, VBUS discharge control, and role swap negotiation. No external PD controller or level-shifter IC is required, reducing bill-of-materials and board area while maintaining full USB-IF compliance.

How does the HRTIM differ from standard advanced timers in the STM32 family?

The HRTIM provides 184 ps resolution (vs. typical 1–5 ns), independent dead-time insertion per channel, synchronous counter reset across all 6 timers, and direct triggering of ADC conversions and DAC updates. It is specifically architected for multi-phase resonant converters and GaN-based inverters requiring sub-nanosecond timing fidelity.

What security features are hardware-accelerated and production-ready?

The device includes AES-128/256 encryption/decryption acceleration, true random number generation (RNG), 96-bit unique device ID, and securable memory areas with proprietary code readout protection (PCROP). These features are silicon-verified and enabled in production silicon-no firmware patching or external crypto co-processor needed.
