The STM32G441RB from STMicroelectronics is a 32-Bit Arm Cortex-M4 Microcontroller designed for high-performance embedded control, industrial automation, motor control and advanced signal-processing applications. Built around an Arm Cortex-M4 core with an integrated Floating-Point Unit (FPU) operating at up to 170 MHz, it delivers powerful computing performance while integrating 128 KB of Flash memory and 32 KB of SRAM. The microcontroller also incorporates advanced security features including readout protection, write protection, securable memory areas and proprietary code readout protection to safeguard critical applications.
This microcontroller integrates two fast 12-bit ADCs with sampling rates up to 5 Msps, four DAC channels, four comparators, three operational amplifiers and an internal voltage reference buffer for precise analog signal processing. It also incorporates dedicated hardware accelerators including a CORDIC unit for trigonometric calculations and an FMAC unit for digital filter functions, improving computational efficiency for real-time applications. Communication interfaces include three I²C ports, three SPI interfaces multiplexed with two half-duplex I²S interfaces, three USARTs, one UART, one low-power UART, one FDCAN interface, one SAI interface, USB device support, UCPD connectivity and integrated AES encryption for enhanced security.
Designed for versatility and high-performance control applications, the STM32G441RB supports one general-purpose 32-bit timer, two 16-bit PWM timers for motor control, seven general-purpose 16-bit timers and one 16-bit low-power timer. Operating from a supply voltage range of 1.71 to 3.6 V and specified for temperatures from -40°C to +85°C, it ensures reliable operation across demanding environments. Compact and feature-rich, this microcontroller is housed in a package measuring 12.0 × 12.0 × 1.6 mm, making it ideal for industrial control systems, motor drives, power conversion equipment, consumer electronics and embedded applications requiring advanced processing and connectivity capabilities.
