　　2 Description

　　The STM32F103xx medium-density performance line family incorporates the highperformance ARM Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency， highspeed embedded memories （Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes），

　　and an extensive range of enhanced I/Os and peripherals connected to two APB buses. 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 devices operate from a 2.0 to 3.6 V power supply. They are 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 the design of low-power applications.

　　The STM32F103xx medium-density performance line family includes devices in six 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 medium-density performance line microcontroller

　　family suitable for a wide range of applications such as motor drives， application control，

　　medical and handheld equipment， PC and gaming peripherals， GPS platforms， industrial

　　applications， PLCs， inverters， printers， scanners， alarm systems， video intercoms， and

　　HVAC
