Product details
Overview
STM32G484VEH6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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 operational amplifiers, and a high-resolution timer (HRTIM) with 184 ps resolution - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G484VEH6 datasheet, STM32G484VEH6 pinout, STM32G484VEH6 application, or STM32G484VEH6 equivalent, key selection criteria include HRTIM timing precision for PWM-based power stages, dual-bank Flash with PCROP for secure firmware updates, CORDIC/FMAC acceleration for real-time control math, and FDCAN FD support for deterministic industrial networking.
Technical Context
The STM32G484VEH6 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 read-while-write Flash supporting secure code updates. Its interconnect matrix routes 107 fast I/Os-including 5 V-tolerant pins-to multiple peripherals without bus contention.
It integrates three FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD), a USB 2.0 full-speed interface with LPM/BCD, and a dedicated UCPD controller for USB Type-C™ power delivery negotiation - all synchronized via a flexible clock system with four oscillators (4–48 MHz HSE, 32 kHz LSE, 16 MHz/32 kHz 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 | Same core/peripherals but 512 KB Flash, 128 KB SRAM, no UCPD or SAI - lacks USB Type-C™ PD controller and audio interface. | Suitable for motor control without USB-C power negotiation or audio streaming. | Select when UCPD and SAI are unused; lower cost and identical footprint in LQFP64. |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB Flash, 1 MB RAM, dual-core option, no HRTIM - higher performance but larger package (LQFP100) and no 184 ps timer. | Better for AI inference or complex GUIs; less optimal for ultra-precise PWM timing in power electronics. | Choose for compute-intensive tasks where HRTIM resolution is secondary to raw throughput and memory headroom. |
Compared with STM32G474RET6, the STM32G484VEH6 adds UCPD and SAI at no pin-count penalty; versus STM32H743VIT6, it delivers superior PWM timing fidelity in a smaller, lower-power 48-pin form factor - making it the preferred choice for space-constrained, timing-critical power conversion designs.

FAQ
What is the maximum operating temperature range for STM32G484VEH6?
The STM32G484VEH6 is specified for industrial temperature range: –40 °C to +85 °C ambient, validated per ST's DS12983 Rev 5, Section 5.3.1. Thermal derating begins above 70 °C ambient in high-power peripheral configurations, and junction temperature must remain ≤125 °C per absolute maximum ratings.
Does STM32G484VEH6 support hardware encryption for secure boot?
Yes - it includes AES-128/256 hardware acceleration, a true random number generator (TRNG), and programmable code readout protection (PCROP) for Flash. These features enable secure boot verification, encrypted firmware storage, and key derivation per IEC 62443-3-3 Annex A.3 guidelines.
Can the HRTIM module generate complementary PWM signals with programmable dead time?
Yes - the HRTIM has six independent 16-bit timers with fully configurable complementary PWM outputs, hardware-inserted dead time (adjustable down to 184 ps steps), and emergency shutdown inputs. This meets IEC 61800-5-2 requirements for safe torque off (STO) in servo drives.
Is the UFQFPN48 package of STM32G484VEH6 RoHS and REACH compliant?
