MSM63P180

• Power supply backup

Backup circuit (voltage multiplier) enables operation at 1.45 V minimum

• Timers and counter

8-bit timer ¥ 4

Selectable as auto-reload mode/capture mode/clock frequency measurement mode

Watchdog timer ¥ 1

Overflows in 2 sec.

100 Hz timer ¥ 1

Measurable in steps of 1/100 sec.

15-bit time base counter ¥ 1

1, 2, 4, 8, 16, 32, 64, and 128 Hz signals can be read

• Time base capture function

Captures the time base counter output values (32, 64, 128, and 256 Hz) upon the rise (fall) of

P1.0 and P1.1

• Serial port

: 14 (watchdog timer interrupt is a nonmask-

able interrupt)

• Operating voltage

When backup used

When backup not used

: VDD = 1.45 to 2.7 V

: VDD = 2.7 to 5.5 V
