STM32F103VEMainstream Performance line, ARM Cortex-M3 MCU with 512 Kbytes Flash, 72 MHz CPU, motor control, USB and CAN
The STM32F103xC, STM32F103xD and STM32F103xE 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. All devices offer three 12-bit ADCs, four 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 STM32F103xC/D/E high-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.
These features make the STM32F103xC/D/E high-density performance 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 intercom, and HVAC.Key FeaturesCore: ARM® 32-bit Cortex®-M3 CPU72 MHz maximum frequency, 1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory accessSingle-cycle multiplication and hardware divisionMemories256 to 512 Kbytes of Flash memoryup to 64 Kbytes of SRAMFlexible static memory controller with 4 Chip Select.
