Product details
Overview
STM32G483CET3 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 operational amplifiers, and hardware math accelerators (CORDIC, FMAC) - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G483CET3 datasheet, STM32G483CET3 pinout, STM32G483CET3 application, or STM32G483CET3 equivalent, key selection criteria include its dual-bank read-while-write Flash architecture, FDCAN support for automotive-grade communication, UCPD interface for USB Type-C™ power delivery, and 5 V-tolerant GPIOs enabling direct interfacing with legacy logic levels.
Technical Context
The STM32G483CET3 implements an Adaptive Real-time Accelerator (ART) enabling zero-wait-state execution from Flash memory, paired with a Memory Protection Unit (MPU) and securable memory regions including PCROP and 1 KB OTP. Its interconnect matrix routes 16 DMA channels across multiple AHB/APB buses for deterministic peripheral access.
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 supporting USB Power Delivery 3.0 negotiation - all synchronized via a flexible clock tree 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 microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32G474RET6 | Same core/peripherals but 512 KB Flash in LQFP64; lacks UCPD and one FDCAN channel. | Suitable for motor control where USB-C PD is not required; larger package allows easier routing in prototyping. | Select when UCPD is unnecessary and board layout favors LQFP64 over UFQFPN48. |
| STM32H743VIT6 | Cortex-M7 core @ 480 MHz, 2 MB Flash, dual-core option, no CORDIC/FMAC; higher power and cost. | Targeted at high-end HMI or AI-edge inference; overqualified for cost-sensitive digital power or motor control. | Choose only if >200 DMIPS, large memory, or dual-core RTOS partitioning is mandatory. |
Compared with STM32G474RET6, the STM32G483CET3 adds USB-C PD capability and third FDCAN channel in a smaller footprint; versus STM32H743VIT6, it delivers optimized analog/motor control features at lower power and cost - making it the preferred choice for embedded power electronics and industrial motion.

FAQ
What is the maximum operating temperature range for STM32G483CET3?
The STM32G483CET3 is qualified for industrial temperature range: –40 °C to +85 °C ambient, verified per JEDEC JESD47 stress testing. Thermal characteristics in the datasheet (Section 6.10) specify junction-to-ambient thermal resistance (RθJA) of 41.5 °C/W for UFQFPN48 package under standard PCB conditions.
Does STM32G483CET3 support hardware encryption for secure boot?
Yes - it integrates AES-128/AES-256 hardware accelerator, 96-bit unique device ID, and securable memory areas with PCROP. Secure boot can be implemented using ROM-based bootloader with signature verification, leveraging embedded flash protection and hash calculation unit (CRC + RNG).
Can the CORDIC unit perform inverse trigonometric functions?
Yes - the CORDIC engine supports both forward (sin, cos, tan) and inverse (arcsin, arccos, arctan) trigonometric functions, as well as hyperbolic, logarithmic, and square-root operations. It operates in rotation or vectoring mode with configurable precision (16–32 iterations) via dedicated registers.
How many simultaneous ADC conversions can be triggered by TIM1 in STM32G483CET3?
TIM1 can trigger up to four ADCs simultaneously via TRGO events (TRGO2/3/4), enabling synchronized sampling across multiple analog channels - critical for three-phase motor current reconstruction and isolated voltage monitoring in digital power topologies.
