Introduction

This datasheet provides the ordering information and mechanical device characteristics of

the STM32F103x8 and STM32F103xB medium-density performance line microcontrollers.

For more details on the whole STMicroelectronics STM32F103xx family, please refer to

Section 2.2: Full compatibility throughout the family.

The medium-density STM32F103xx datasheet should be read in conjunction with the low-,

medium- and high-density STM32F10xxx reference manual.

The reference and Flash programming manuals are both available from the

Description

The STM32F103x8 and STM32F103xB 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 STM32F103xx medium-density 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

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:

●

Motor drive and application control

●

Medical and handheld equipment

●

PC peripherals gaming and GPS platforms

●

Industrial applications: PLC, inverters, printers, and scanners

●

Alarm systems, Video intercom, and HVAC

Figure 1 shows the general block diagram of the device family.
