Description
The STM32F103xx 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 128Kbytes 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
2
and advanced communication interfaces: up to two I Cs and SPIs, three USARTs, an USB
and a CAN.
The STM32F103xx performance line family operates in the −40 to +105 °C temperature
range, from a 2.0 to 3.6 V power supply. A comprehensive set of power-saving mode allows
to design low-power applications.
The complete STM32F103xx performance line family includes devices in 4 different
package types: from 48 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 line microcontroller family suitable for
a wide range of applications:
■
Motor drive and application control
