All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN. The STM32F103xx performance line family operates from a 2.0 to 3.6 V power supply. It is available in both the −40 to +85 °C temperature range and the −40 to +105 °C extended temperature range. A comprehensive set of power-saving mode allows to design low-power applications. The complete STM32F103xx performance line family includes devices in 5 different package types: 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 STM32F103xx performance li
