Product details

512 KB Flash, 48 KB RAM — memory headroom for the BOM

The STM32F101VET6 runs at 36 MHz and includes DMA, PDR, POR, PVD, PWM, a temperature sensor, and a watchdog timer.

80 I/O in a 100-LQFP — what the pin count buys you

With 80 general-purpose I/O lines brought out to a 100-LQFP package (14x14 mm body), this part suits designs that need parallel LCD interfaces, multiple UART/USART channels, or a bank of GPIO for sensor/actuator control. The 100-LQFP is a common footprint for mid-density STM32F1 parts, so a layout can often be shared across a range of Flash and RAM options within the family.

Frequently asked questions

How many I/O pins does STM32F101VET6 have?

The device provides 80 general-purpose I/O lines in a 100-LQFP package.

What are the alternatives to STM32F101VET6?

Within the STM32F1 series, pin-compatible parts with different Flash/RAM densities share the same 100-LQFP footprint. The STM32F103VE adds a full-speed USB 2.0 interface and a second ADC, while the STM32F101VD has 384 KB Flash. All share the same ARM Cortex-M3 core and peripheral set, so a firmware port is straightforward.
