The slope A/D converter handles the ratiometric sensor input (typically a resistive bridge or thermistor) without an external ADC. Combined with the brown-out detect and POR, the part is a single-chip solution for a utility meter or industrial panel display.
The 48 I/O lines give ample headroom for a segment LCD (up to 160 segments with the internal driver), pushbuttons, and a serial interface to a radio module or external EEPROM.
It has 8 KB of Flash program memory (8K x 8 + 256B) and 256 x 8 bytes of RAM.
