This MCU includes DMA, a programmable voltage detector (PVD), power-on reset (POR), power-down reset (PDR), a temperature sensor, and a watchdog timer — all standard on the STM32F1 line. For communication it has I²C, IrDA, LINbus, SPI, and UART/USART interfaces, so it can talk to serial sensors, displays, or a host controller over a few wires. With 80 I/O pins in the 100-LQFP package, there is plenty of headroom for parallel buses or a large button/LED matrix.

Frequently asked questions
What is the difference between STM32F100VBT6 and STM32F100VBT6B?
The STM32F100VBT6B is a later revision of the STM32F100VBT6. The 'B' suffix typically indicates a minor silicon revision with improved errata or manufacturing process. Both are pin-compatible and share the same 24 MHz core, 128 KB Flash, 8 KB RAM, and 100-LQFP package. For new designs, the STM32F100VBT6B is the recommended ordering code.
