PRELIMINARY INFORMATION 1 TC1232 MICROPROCESSOR MONITOR FEATURES s s s s s Precision Voltage Monitor ....................... Adjustable +4.5V or +4.75V Reset Pulse Width ............................. 250msec Min No External Components Adjustable Watchdog Timer ........................ 150msec, 600msec or 1.2sec Debounced Manual Reset Input for External Override 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.
