Product details
Overview
STM32G441CBU6 from STMicroelectronics is an Arm® Cortex®-M4 32-bit 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), 4 comparators, 3 op-amps, and hardware math accelerators (CORDIC, FMAC). It targets motor control, digital power conversion, and industrial sensing systems requiring real-time signal processing and mixed-signal integration.
For engineers reviewing the STM32G441CBU6 datasheet, STM32G441CBU6 pinout, STM32G441CBU6 application, or STM32G441CBU6 equivalent, key selection considerations include its 48-pin UFQFPN package, FDCAN support for flexible data-rate automotive/industrial networks, USB Full-Speed + UCPD for USB Type-C™ power delivery control, and hardware AES-128/256 encryption for secure firmware updates and communication.
Technical Context
The STM32G441CBU6 implements a tightly coupled Cortex-M4 core with FPU and Adaptive Real-Time (ART) Accelerator enabling zero-wait-state execution from Flash at 170 MHz. Its interconnect matrix routes 14 timers-including two 16-bit advanced motor-control timers with dead-time generation and emergency stop-alongside dual ADCs and four DAC channels across shared buses without arbitration bottlenecks.
It integrates domain-specific hardware: CORDIC for real-time trigonometric computation in motor vector control, FMAC for IIR/FIR filter acceleration in digital power loops, and UCPD peripheral supporting USB Power Delivery 3.0 negotiation and Type-C port controller functions-all operating independently of CPU load while sharing clock and reset domains with the main MCU subsystem.

FAQ
What is the maximum operating frequency and associated DMIPS rating of the STM32G441CBU6?
The STM32G441CBU6 operates at up to 170 MHz with an integer performance rating of 213 DMIPS, measured using the Dhrystone 2.1 benchmark. This performance level is sustained under zero-wait-state conditions thanks to the ART Accelerator, which eliminates Flash access latency during instruction fetches.
Does the STM32G441CBU6 support USB Type-C™ Power Delivery, and what hardware enables it?
Yes-the STM32G441CBU6 integrates a dedicated USB Type-C™ and Power Delivery (UCPD) controller compliant with USB PD 3.0. It includes hardware policy engine, CC line monitoring, VCONN switching, and BMC encoding/decoding logic, eliminating the need for an external UCPD IC in USB-C enabled designs.
How many analog-to-digital converters does the STM32G441CBU6 include, and what are their key timing specifications?
The device includes two independent 16-bit ADCs with up to 23 input channels each, capable of 0.25 µs conversion time (4 MSPS per ADC). Both support hardware oversampling up to 16×, achieving effective resolution up to 18 bits, and feature fully synchronous sampling for multi-channel phase-critical measurements.
What low-power modes are supported, and what is the typical current draw in Stop 0 mode?
The STM32G441CBU6 supports Sleep, Stop 0, Stop 1, Standby, and Shutdown modes. In Stop 0 mode-with Flash powered down, SRAM retained, and RTC active-the typical current consumption is 1.2 µA at 3.3 V and 25°C, making it suitable for battery-backed sensor wake-up applications with sub-2 µA quiescent draw.
