The STM32F103VCT6 from STMicroelectronics is a high-density member of the STM32F103 performance line featuring a 72MHz ARM Cortex-M3 core with 256KB Flash and 48KB SRAM. The device integrates 3 x 12-bit ADCs, 2 x 12-bit DACs, USB 2.0 full-speed, CAN 2.0B, SDIO, and 13 communication interfaces. Eleven timers include motor control PWM with dead-time generation. A 12-channel DMA controller offloads data transfers. The 100-LQFP package provides 80 I/O pins, most 5V-tolerant.

The STM32F103VCT6 is built around an ARM Cortex-M3 32-bit RISC core executing Thumb-2 instructions at up to 72MHz, delivering 1.25 DMIPS/MHz. The NVIC supports up to 60 maskable interrupts with 16 priority levels. The multi-AHB bus matrix allows concurrent access to Flash, SRAM, and peripherals. The USB device controller implements a full-speed USB 2.0 endpoint. The CAN controller follows CAN 2.0B with hardware message filtering. Multiple low-power modes (Sleep, Stop, Standby) optimize power consumption.

Pin Group Count Function
GPIO 80 5V-tolerant general-purpose I/O
VDD/VSS 4 pairs Power supply and ground
VDDA/VSSA 1 pair Analog supply for ADC/DAC
VBAT 1 Battery backup for RTC
NRST 1 System reset (active low)
BOOT0/1 2 Boot mode selection
