Overview
STM32G4A1KEU6TR from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU and ART Accelerator, operating up to 170 MHz (213 DMIPS), featuring 512 KB Flash with ECC, 112 KB SRAM (96 KB + 16 KB CCM), and integrated analog peripherals including three 16-bit ADCs, four 12-bit DACs, four rail-to-rail comparators, and four operational amplifiers - deployed in motor control, digital power conversion, and industrial sensing systems.
For engineers reviewing the STM32G4A1KEU6TR datasheet, STM32G4A1KEU6TR pinout, STM32G4A1KEU6TR application, or STM32G4A1KEU6TR equivalent, key selection considerations include its dual FDCAN support for automotive/industrial networking, CORDIC/FMAC hardware accelerators for real-time math, UCPD interface for USB Type-C™ power delivery, and 5 V-tolerant I/Os enabling direct interfacing with legacy logic.
Technical Context
The device implements an Arm Cortex-M4 core with floating-point unit and Memory Protection Unit (MPU), paired with ST's Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. It integrates dual FDCAN controllers compliant with ISO 11898-1:2015 for flexible data-rate communication up to 5 Mbps.
Analog subsystem includes three independent 16-bit ADCs (0.25 µs conversion, up to 36 channels), four 12-bit DACs (2 buffered external @ 1 MSPS, 2 unbuffered internal @ 15 MSPS), and four fully accessible op-amps configurable in PGA mode - all supported by internal voltage reference buffer (2.048 V / 2.5 V / 2.9 V outputs) and hardware parity on critical SRAM blocks.

FAQ
What is the maximum operating frequency and associated performance metric?
The STM32G4A1KEU6TR operates at up to 170 MHz with an integer performance rating of 213 DMIPS (Dhrystone MIPS), validated using the ARM Dhrystone benchmark v2.1 under conditions of zero-wait-state Flash execution enabled by the ART Accelerator. Its FPU supports IEEE 754 single-precision operations essential for motor control and sensor fusion algorithms.
Does this MCU support USB Type-C™ Power Delivery, and how is it implemented?
Yes - the STM32G4A1KEU6TR integrates a dedicated USB Type-C™ and Power Delivery (UCPD) peripheral compliant with USB PD 3.0 specification. It provides hardware-level CC line monitoring, VCONN switching, BMC encoding/decoding, and policy engine support, eliminating the need for an external PD controller in compact USB-C source/sink designs.
How many analog-to-digital converters does it include, and what are their key resolution and speed specs?
The device integrates three independent 16-bit ADCs capable of 0.25 µs conversion time (up to 4 MSPS), supporting up to 36 input channels with hardware oversampling to enhance effective resolution. Each ADC features programmable sampling time, injected/conversion modes, and direct DMA access - optimized for simultaneous current/voltage sensing in motor drives.
What low-power modes are available, and what is the typical current draw in standby mode?
It supports Sleep, Stop, Standby, and Shutdown low-power modes. In Standby mode with RTC active and backup registers retained, typical current consumption is 0.8 µA at 25°C (VDD = 3.3 V). Wake-up latency from Standby is <5 µs, and the device retains full SRAM content in Stop modes with regulator ON.
