STM32FG103RBT6 – STMicroelectronics

The STMicroelectronics STM32FG103RBT6 is a high-density performance line, 32-bit microcontroller based on the ARM Cortex-M3 core, operating at a maximum frequency of 72 MHz. It features 128 KB of Flash memory and 20 KB of SRAM, making it suitable for applications requiring moderate program and data storage. The device incorporates a comprehensive set of peripherals including two 12-bit ADCs, three general-purpose 16-bit timers, and standard communication interfaces like USART, SPI, and I2C. Its typical voltage range is 2.0V to 3.6V, and the outputs can typically source or sink up to 25mA. The device is housed in a 64-pin LQFP package, ideal for surface mount applications. It operates reliably across an operating temperature range of –40°C to 85°C. Common use cases include industrial control, motor control, and small appliance applications, where its balance of processing power, memory, and peripherals offers a cost-effective and efficient solution.
