MCU 32-bit STM32F ARM Cortex M3 RISC 64KB Flash 2.5V/3.3V 48-Pin VFQFPN T/R

The STM32F101xB and STM32F101x8 medium-density access line family incorporates the high-performance ARM Cortex -M3 32-bit RISC core operating at a 36 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 16 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (two I²Cs, two SPIs, and up to three USARTs), one 12-bit ADC and three general-purpose 16-bit timers.The STM32F101xx medium-density access line family 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.The STM32F101xx medium-density access line family includes devices in four different packages ranging from 36 pins to 100 pins. Depending on the device chosen, different sets of peripherals are included, the description below gives an overview of the complete range of peripherals proposed in this family.These features make the STM32F101xx medium-density access line microcontroller family suitable for a wide range of applications such as application control and user interface, medical and handheld equipment, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, Video intercoms, and HVACs.
