The STM32F100xx value line family incorporates the high-performance ARM Cortex -M3 32-bit RISC core operating at a 24 MHz frequency, high-speed embedded memories (Flash memory up to 512 Kbytes and SRAM up to 32 Kbytes), a flexible static memory control (FSMC) interface (for devices offered in packages of 100 pins and more) and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (up to two I²Cs, three SPIs, one HDMI CEC, up to three USARTs and 2 UARTS), one 12-bit ADC, two 12-bit DACs, up to 9 general-purpose 16-bit timers and an advanced-control PWM timer.The STM32F100xx high-density value line family operates in the –40 to +85 °C and –40 to +105 °C temperature ranges, 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 STM32F100xx value line family includes devices in three different packages ranging 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.These features make the STM32F100xx value line microcontroller family suitable for a wide range of applications such as motor drives, application control, medical and handheld equipment, PC and gaming peripherals, GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
