The STM32F103ZGH6 microcontroller has 1 MB of Flash, 64 KB RAM, 3x21-channel 12-bit A/D converter, 6x16-bit (IC/OC/PWM) timer, 3xSPI, 2I2S, 2x12C, 5USART, SDIO, USB, CAN, 112 I/Os in a 144-pin 20 mm x 20 mm x 1.4 mm LQFP package.

The STM32F103ZGH6 performance line family incorporates the high performance ARM® Cortex™-M3 32-bit RISC core operating at a 72 MHz frequency, highspeed embedded memories (Flash memory up to 1 Mbyte and SRAM up to 96 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer three 12-bit ADCs, ten general-purpose 16-bit timers plus two PWM timers, as well as standard and advanced communication interfaces: up to two I2Cs, three SPIs, two I2Ss, one SDIO, five USARTs, an USB and a CAN.

The STM32F103xx XL-density 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 the design of low-power applications. The STM32F103xx XL-density performance line family offers devices in four different package types: from 64 pins to 144 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.
