The STM32F103VET6 medium-density 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 512 Kbytes and SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.The ARM Cortex-M3 32-bit RISC processor features exceptional code efficiency, delivering high performance which is expected from an ARM core in the memory size usually associated with 8-bit and 16-bit devices. The STM32F103 Performance Line family has an embedded ARM core and is therefore compatible with all ARM tools and software. It combines the high performance ARM Cortex-M3 CPU with an extensive range of peripheral functions and enhanced I/O capabilities.
