Product details
Overview
STM32G483RET6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating at 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 DAC channels, six rail-to-rail op-amps, and three FDCAN controllers. It targets motor control, digital power conversion, and industrial sensing systems requiring real-time math acceleration and high-precision analog signal chain integration.
For engineers reviewing the STM32G483RET6 datasheet, STM32G483RET6 pinout, STM32G483RET6 application, or STM32G483RET6 equivalent, this page delivers verified technical context, validated pin functions for LQFP64, confirmed analog/motor control capabilities, and direct alternative part comparisons - all grounded in ST's DS12997 Rev 4 production data.
Technical Context
The STM32G483RET6 implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash memory, paired with dual-bank read-while-write architecture for seamless firmware updates. Its CORDIC and FMAC hardware accelerators offload trigonometric and filtering computations from the CPU core.
It integrates three FDCAN controllers supporting flexible data-rate (up to 5 Mbps), 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 multi-AHB interconnect matrix and programmable clock tree with four PLLs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same LQFP64 package and core, but 512 KB Flash, 128 KB SRAM, and identical peripheral set - lacks UCPD controller and one FDCAN channel. | Suitable for motor control or power conversion where USB-C PD is not required; lower BOM cost when UCPD is unused. | Select when USB-C power delivery negotiation is unnecessary and cost optimization is prioritized over feature redundancy. |
| STM32H743VIT6 | Higher-tier Cortex-M7 (480 MHz), 2 MB Flash, 1 MB RAM, dual-core option, but larger LQFP100 package and higher power consumption. | Targeted at complex HMI, AI edge inference, or multi-protocol gateways - over-spec'd for standalone motor/power control. | Choose only if application demands >200 MHz compute headroom, dual-core RTOS partitioning, or external SDRAM interface. |
Compared with STM32G474RET6, the G483RET6 adds UCPD and third FDCAN for USB-C PD and redundant CAN networks; versus STM32H743VIT6, it delivers optimal analog/motor integration in compact LQFP64 at lower power and cost - ideal for cost-sensitive, mixed-signal embedded control.

FAQ
What is the maximum operating frequency and associated performance metric of the STM32G483RET6?
The STM32G483RET6 operates at up to 170 MHz, delivering 213 DMIPS (Dhrystone MIPS) with its Arm Cortex-M4 core and FPU. This performance level is sustained using the ART Accelerator for zero-wait-state Flash execution, enabling deterministic real-time response in motor control and digital power applications.
Does the STM32G483RET6 support hardware-accelerated cryptographic operations?
Yes - it integrates a dedicated AES-128/256 hardware accelerator and a true random number generator (RNG). These enable fast, low-power encryption/decryption of firmware images or communication payloads without consuming CPU cycles, meeting requirements for secure boot and authenticated data exchange.
How many analog-to-digital converter (ADC) units does the STM32G483RET6 include, and what are their key timing specifications?
The device includes five independent 12-bit ADCs supporting up to 42 input channels. Each achieves 0.25 µs conversion time (4 MSPS), with hardware oversampling enabling effective resolution up to 16 bits. The ADCs support synchronous sampling across multiple units - critical for three-phase current sensing in motor control.
Is the STM32G483RET6 pin-compatible with other members of the STM32G4 series in the same LQFP64 package?
Yes - the STM32G483RET6 shares identical pinout and electrical characteristics with other STM32G4x3 devices in LQFP64 (e.g., STM32G473RET6, STM32G431RET6), allowing drop-in replacement within the same memory/peripheral configuration tier. However, UCPD and third FDCAN functionality are exclusive to G483 variants.
