l
Two general purpose 16-bit timers
Controls up to 128 segments
Supports static, 2-mux, 3-mux, and 4-mux displays
On-chip bias generation with internal charge pump
Low power blink capability
Expands GPIO count by up to 36 pins
GPIO pins may be configured to push-pull or open-
drain outputs with two drive levels. GPIO may also
be used as digital inputs
Port Match Capability can wake up host controller
using interrupt pin
5 V Tolerant I/O
Precision time keeping with 32.768 kHz watch crys-
tal; self-oscillate mode requires no external crystal;
accepts external 32 kHz CMOS clock
36-hour programmable counter with wake up alarm
Can wake up the host controller using interrupt pin
Low power (<1.5 µA)
General purpose RAM expands the memory avail-
able to host controller.
20 MHz Internal oscillator
Can be clocked from an external CMOS clock
