Description
The STM32F103x4 and STM32F103x6 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 32 Kbytes and SRAM up to 6 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 I
USARTs, an USB and a CAN.
The STM32F103xx low-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 low-density performance line family includes devices in four different
package types: from 36 pins to 64 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 low-density performance line microcontroller family
suitable for a wide range of applications:
