The STM32F103C8T6 microcontroller has 64 KB of Flash, 20 KB RAM, 2x10-channel 12-bit A/D converter, 4x16-bit (IC/OC/PWM) timer, 2xSPI, 2x12C, 3USART, USB, CAN, 37 I/Os in a 48-pin 7 mm x 7 mm x 1.4 mm LQFP package.
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 I2Cs and SPIs, three 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.
