Description

MICROPROCESSOR MONITOR SMD 1232
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.
