PRINCIPLES OF OPERATION
Power On Reset
Application of power to the X5163/X5165 activates a
Power On Reset Circuit. This circuit goes active at 1V
and pulls the RESET/RESET pin active. This signal
prevents the system microprocessor from starting to
operate with insufficient voltage or prior to stabilization
of the oscillator. When V

exceeds the device V
TRIP
Low Voltage Monitoring
During operation, the X5163/X5165 monitors the V
level and asserts RESET/RESET if supply voltage falls
below a preset minimum V
signal prevents the microprocessor from operating in a
power fail or brownout condition. The RESET/RESET
signal remains active until the voltage drops below 1V.
It also remains active until V

Watchdog Timer
The Watchdog Timer circuit monitors the microproces-
sor activity by monitoring the WDI input. The micropro-
cessor must toggle the CS/WDI pin periodically to
prevent a RESET/RESET signal. The CS/WDI pin
must be toggled from HIGH to LOW prior to the expira-
tion of the watchdog time out period. The state of two
nonvolatile control bits in the Status Register deter-
mine the watchdog timer period. The microprocessor
can change these watchdog bits, or they may be
“l(fā)ocked” by tying the WP pin LOW and setting the
WPEN bit HIGH.
V
The X5163/X5165 has a standard V
(V
TRIP
) voltage. This value will not change over normal
operating and storage conditions. However, in applica-
tions where the standard V
for higher precision in the V
X5165 threshold may be adjusted.

Setting the V
This procedure sets the V
value. For example, if the current V

is 4.6V, this procedure directly makes the
change. If the new setting is lower than the current set-
ting, then it is necessary to reset the trip point before
setting the new value.
