Overview
The STM32F101C6T6A is a microcontroller from STMicroelectronics, part of the STM32F101x6 Low-density access line family. This device is built around the high-performance ARM® 32-bit Cortex®-M3 CPU, operating at a maximum frequency of 36 MHz and delivering 1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory access. It features high-speed embedded memories, including 16 to 32 Kbytes of Flash memory and 4 to 6 Kbytes of SRAM. The microcontroller is designed to operate in a wide temperature range of –40 to +85 °C and supports a power supply range of 2.0 to 3.6 V.
The STM32F101C6T6A includes an extensive range of peripherals and I/Os connected to two APB buses, such as standard communication interfaces (I2C, SPI, and USARTs), a 12-bit ADC, and multiple timers. The device also supports low-power modes, including Sleep, Stop, and Standby modes, making it suitable for low-power applications.
