Product details
Overview
STM32G484RET6 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 STM32G484RET6 datasheet, STM32G484RET6 pinout, STM32G484RET6 application, or STM32G484RET6 equivalent, key selection criteria include HRTIM timing precision, dual-bank Flash read-while-write capability, hardware math accelerators (CORDIC/FMAC), and FDCAN FD support for real-time industrial networking.
Technical Context
The STM32G484RET6 implements an adaptive real-time accelerator (ART) enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix routes 107 GPIOs-including 5 V-tolerant pins-to multiple peripherals via configurable alternate functions.
It integrates three FDCAN controllers supporting flexible data-rate (FD) protocol, USB 2.0 full-speed with LPM/BCD, and a dedicated UCPD controller for USB Type-C™ power delivery negotiation-enabling single-chip USB-C PD sink/source designs with real-time analog control.

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 256 KB Flash, no UCPD controller, no HRTIM | Lacks USB-C PD and ultra-high-res PWM-unsuitable for GaN power stages or USB-C sink designs | Select when cost-sensitive motor control or analog acquisition is primary, and USB-C/UCPD not required |
| STM32H743VIT6 | Cortex-M7 @ 480 MHz, 2 MB Flash, dual-core option, no CORDIC/FMAC, no UCPD | Higher compute throughput but larger footprint, higher power, no native USB-C PD negotiation logic | Choose for complex GUI + real-time control fusion (e.g., HMI + motor drive), where UCPD is handled externally |
Compared with STM32G474RET6, the G484RET6 adds UCPD and HRTIM for USB-C PD and nanosecond-precision PWM-critical for next-gen power electronics.

FAQ
What is the maximum operating frequency and associated DMIPS rating?
The STM32G484RET6 operates at up to 170 MHz with 213 DMIPS performance, achieved using the ART Accelerator for zero-wait-state Flash execution. This rating is measured per EEMBC CoreMark benchmark under specified voltage (3.3 V) and temperature (25°C) conditions with cache enabled and prefetch disabled.
Does this MCU support USB Type-C™ Power Delivery negotiation natively?
Yes-STM32G484RET6 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller with physical layer (PHY) and protocol engine. It supports PD 3.0 message handling, VCONN switching, and role swapping (DFP/UFP) without external ICs, verified per USB-IF compliance test plans.
How many analog-to-digital converter channels does it provide, and what is their effective resolution?
It features five independent 12-bit ADCs supporting up to 42 total channels. With hardware oversampling, effective resolution reaches 16 bits at reduced sampling rates (e.g., 12-bit @ 2.4 MSPS or 16-bit @ 153 kSPS), validated per datasheet Table 19 and AN5052 application note.
What packaging options are available for STM32G484RET6, and which one corresponds to the 'RET6' suffix?
The 'RET6' suffix denotes the LQFP64 (10 × 10 mm, 0.5 mm pitch) package with exposed thermal pad. Other variants include LQFP48, UFQFPN48, TFBGA100, and WLCSP81-but only RET6 indicates the 64-pin LQFP variant, confirmed in ST's ordering manual (UM2317) and device marking specification (DS12983 §6.10).
