Pin Name

Function

PBRST

Debounced manual pushbutton reset input.

2TD

Watchdog time delay selection. (tTD = 150ms for TD = GND, tTD = 610ms for

TD=Open, and tTD = 1200ms for TD = VCC).

3TOL

Selects 10% (TOL connected to GND) or 20% (TOL connected to VCC) trip point

tolerance.

GND

Ground.

RESET

Active HIGH reset output. RESET is active:

1. If VCC falls below the reset voltage trip point.

2. If PBRST is LOW.

3. If ST is not strobed LOW before the timeout period set by TD expires.

4. During power-up.

RESET

Active LOW reset output. (See RESET).

7ST

Strobe input.

VCC

3.3V power.
