General Description
The TC1232 is a fully-integrated processor supervisor
that 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 250 msec after VCC is
within tolerance to ensure a stable system start-up.
Microprocessor sanity is monitored by the onboard
watchdog circuit. The microprocessor must provide a
periodic low-going signal on the ST input. Should the
processor fail to supply this signal within the selected
time-out period (150 msec, 600 msec or 1200 msec),
an out-of-control processor 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 PDIP
or SOIC package, a 16-Pin SOIC (wide) package and
requires no external components.
