GENERAL DESCRIPTION
The TC70/71 is a fully-integrated power supply monitor,
watchdog and battery backup circuit in a space-saving
8-pin package.
When power is initially applied, the TC70/71 holds the
processor in its reset state for a minimum of 500msec after
VCC is in tolerance to ensure stable system start-up. After
start-up, processor sanity is monitored by the on-board
watchdog circuit. The processor must provide periodic high-
to-low level transitions to the TC70/71 to verify proper
execution. Should the processor fail to supply this signal
within the specified timeout period, an out-of-control proces-
sor is indicated and the TC70/71 issues a momentary
processor reset as a result. The TC70 also features a
watchdog disable pin to facilitate system test and debug.
The output of the TC70/71 can be wire-ORed to a push-
button switch (or electronic signal) to reset the processor.
When connected to a push-button switch, the TC70/71
provides contact debounce.
The integrated battery backup circuit on-board the TC70/
71 converts CMOS RAM into nonvolatile memory by first
write-protecting, then switching the VCC line of the RAM over
to an external battery.
The TC71 incorporates an additional 1.3V threshold
detector for power fail warning, low battery detection or to
monitor power supply voltages other than +5V.
