STM32G441KBT6 - 170MHz Cortex-M4 MCU | STMicroelectronics

STMicroelectronics STM32G441KBT6 is a 32-bit Arm Cortex-M4 microcontroller with a 170 MHz operating frequency, 128 KB of Flash memory, 32 KB of SRAM, and an FPU in a 32-pin LQFP 7 x 7 mm package. It combines a math accelerator, fast analog peripherals, and extensive connectivity in a compact embedded-control device. A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and communication interfaces on one semiconductor die. Within the embedded hierarchy, the STM32G441KBT6 is an Arm Cortex-M4 MCU, a 32-bit RISC controller within the STM32G4 family. It executes firmware, samples analog signals, controls actuators, and manages industrial, IoT, automation, motor-control, metering, and low-power board designs. The principal device characteristics include 170 MHz execution, 213 DMIPS of compute performance, 128 KB of Flash, and 32 KB of SRAM. Its Cortex-M4F processor includes a floating-point unit and hardware math accelerator for control calculations. STMicroelectronics describes the device as a mainstream Arm Cortex-M4 MCU with medium analog integration, making it suitable for mixed-signal systems that require more control performance and analog capability than a general-purpose entry microcontroller. The 32-pin LQFP package provides a practical route for prototyping and production assemblies that use leaded PCB land patterns. Its 7 x 7 mm body supports compact placement while leaving comparatively generous space between leads for assembly inspection and rework. The product family targets applications requiring deterministic embedded control, efficient peripheral integration, and a familiar STM32G4 software ecosystem. Typical uses include industrial motor controllers, sensor and metering nodes, compact power converters, connected automation equipment, and low-power IoT devices. In these systems, the MCU can execute a control loop, process ADC readings, operate timers and communication peripherals, and supervise safety-critical state without requiring a separate processor. Designers should confirm pin multiplexing, peripheral assignments, clock-tree requirements, analog reference routing, and firmware support in the STM32G441KB product documentation before finalizing a board. Proper decoupling, exposed-ground-plane layout, and signal-integrity practices are especially important when analog and high-speed digital functions operate in the same design. This page combines manufacturer product information with practical selection guidance, comparison criteria, application-fit analysis, and design notes. It is intended to help engineers identify the correct MCU while recognizing that firmware, peripherals, qualification, and lifecycle decisions require validation against current STMicroelectronics documentation.
