STMicroelectronics STM32F103C8T6TR MCU 32-bit Arm Cortex-M3 MCU Overview
STM32F103C8T6TR from STMicroelectronics is a mainstream performance-line STM32F1 microcontroller based on the Arm Cortex-M3 32-bit core. It is designed for embedded control applications that require a balance of processing performance, integrated peripherals, and compact board-level implementation. The device runs at up to 72 MHz and includes 64 KB of Flash memory and 20 KB of SRAM, making it suitable for firmware-driven industrial control, motor control, communication interfaces, handheld equipment, PC peripherals, alarm systems, HVAC controllers, and general embedded applications.
The STM32F103C8T6TR is supplied in a 48-pin LQFP package and supports a 2.0 V to 3.6 V operating supply range. Its integrated peripheral set includes USB, CAN, USART, SPI, I2C, timers, GPIO, and dual 12-bit ADC resources, allowing designers to build compact MCU-based systems with fewer external components. The “TR” suffix indicates tape-and-reel packaging, which is commonly preferred for automated SMT assembly and production-line sourcing.
