Product details
Overview
STM32G441KBT6 from STMicroelectronics is a 32-bit Arm® Cortex®-M4 microcontroller with FPU, operating up to 170 MHz (213 DMIPS), featuring 128 KB Flash with ECC, 32 KB SRAM (22 KB + 10 KB CCM), and integrated analog peripherals including dual 12-bit DACs (1 MSPS buffered), dual 16-bit ADCs (0.25 µs conversion), CORDIC/FMAC math accelerators, and FDCAN for industrial motor control and power conversion systems.
For engineers reviewing the STM32G441KBT6 datasheet, STM32G441KBT6 pinout, STM32G441KBT6 application, or STM32G441KBT6 equivalent, key selection considerations include its 48-pin LQFP package, 1.71–3.6 V supply range, hardware AES-128/256 encryption, ultra-fast comparators, and support for advanced motor control timers with dead-time generation and emergency stop.
Technical Context
The STM32G441KBT6 implements an Arm Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. It integrates dual 16-bit ADCs with hardware oversampling and 23-channel multiplexing, plus four rail-to-rail analog comparators with programmable hysteresis.
Its timing subsystem includes two 16-bit advanced motor control timers (TIM1/TIM8) supporting up to eight PWM channels, dead-time insertion, and emergency stop; one 32-bit general-purpose timer; and a low-power timer (LPTIM1) for precise sub-millisecond wake-up from Stop mode.
