Name

Function

PBRST Debounced manual pushbutton RESET input.

TD

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

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

TOL

Selects 5% (TOL connected to GND) or 10% (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).

ST Strobe input.

VCC 5V power.

NC No internal connection.
