GENERAL DESCRIPTION
The TC1232 is a fully-integrated processor supervisor.
It provides three important functions to safeguard processor
sanity: precision power on/off reset control, watchdog timer
and external reset override.
On power-up, the TC1232 holds the processor in the
reset state for a minimum of 250msec after VCC is within
tolerance to ensure a stable system start-up.
Microprocessor sanity is monitored by the on-board
watchdog circuit. The microprocessor must provide a peri-
odic low-going signal on the ST input. Should the processor
fail to supply this signal within the selected time-out period
(150msec, 600msec or 1200msec), an out-of-control pro-
cessor is indicated and the TC1232 issues a processor reset
as a result.
The outputs of the TC1232 are immediately driven
active when the PB input is brought low by an external push-
button switch or other electronic signal. When connected to
a push-button switch, the TC1232 provides contact
debounce.
The TC1232 is packaged in a space-saving 8-pin plastic
DIP or SOIC package and requires no external components.
