It integrates a 12-bit ADC (12 channels), dual 12-bit DACs, an LCD driver, DMA, and a brown-out detect/reset — enough mixed-signal and display capability to replace several external ICs in a portable instrument or sensor node.
The 80 general-purpose I/O pins, combined with the internal oscillator and brown-out reset, simplify the external BOM for a self-contained controller.
