The STM32F101R4 Low-density access line device incorporates the high-performance ARM Cortex™-M3 32-bit RISC core operating at a 36 MHz frequency, high-speed embedded memories (Flash memory and SRAM), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. The STM32F101R4 offers standard communication interfaces (one I2C, one SPI, and two USARTs), one 12-bit ADC and general-purpose 16-bit timers.
The STM32F101R4 Low-density access line device operates in the –40 to +85 °C temperature range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows the design of low-power applications.
