Description

The STM32F103xx medium-density performance line family incorporates the high

performance ARM Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, high

speed 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

HVACs.
