STM32F101xC, STM32F101xD and STM32F101xE basic series are based on the high performance ARM® Cortex™-M3 core operating at up to 36MHz frequency. The series features a rich set of peripherals including 1x12-bit ADC, 2x12-bit DAC, up to 9 timers, up to 13 communication interfaces as well as 12-channel DMA controller.
The STM32F101xC/D/E series are 32‑bit ARM Cortex‑M3 microcontrollers with up to 512 KB flash, 48 KB SRAM, and a rich set of peripherals including ADC, DAC, multiple timers, USART, SPI, I2C, and FSMC. The devices operate from 2.0 V to 3.6 V and support low‑power modes such as sleep, stop, and standby.
The series is offered in 48‑, 64‑, 100‑ and 144‑pin packages, each with varying peripheral counts. Detailed electrical characteristics, power‑supply options, and ordering information are provided, making the datasheet a comprehensive reference for hardware designers. This manual is written in Chinese.
