Peripherals and connectivity for control-loop designs
On-chip peripherals include DMA, a programmable voltage detector (PVD), power-on reset (POR), a watchdog timer (WDT), and a temperature sensor. Two 12-bit DACs and ten 12-bit ADC channels handle analog I/O without external converters in many mid-range signal chains.
For volume commitments or dual-source qualification, the base product number STM32F100 covers multiple Flash and RAM variants in the same 48-LQFP footprint, providing a pin-compatible upgrade path without a board spin.
