Overview
The STM32F101CBT6TR is a medium-density access line microcontroller from STMicroelectronics, part of the STM32F101xx family. It features the high-performance ARM® 32-bit Cortex®-M3 CPU, operating at a maximum frequency of 36 MHz and achieving 1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory access. This MCU is equipped with up to 128 Kbytes of Flash memory and up to 16 Kbytes of SRAM, along with an extensive range of enhanced peripherals and I/Os connected to two APB buses.
The device supports various communication interfaces, including two I²C, two SPIs, and up to three USARTs. It also includes a 12-bit ADC, three 16-bit timers, and other peripherals such as watchdog timers and a SysTick timer. The STM32F101CBT6TR operates in a temperature range of –40 to +85 °C and is powered by a 2.0 to 3.6 V supply.
