The 100-pin LQFP package (14x14 mm body) provides 88 general-purpose I/O lines, enough to interface with parallel displays, external memory buses, or a dense sensor array without an I/O expander.
Peripheral set and analog integration
On-chip data converters include a 19-channel 12-bit ADC and two 12-bit DAC channels, which can handle multiple analog sensor inputs and generate analog setpoints or reference voltages without external converters.
Housed in a 100-LQFP (14x14 mm) surface-mount package, the footprint is shared with other STM32F0 devices in the same pin count, easing a PCB layout that might later migrate between density options.
