DESCRIPTION
The X4283/85 combines four popular functions,
Power-on Reset Control, Watchdog Timer, Supply Volt-
age Supervision, and Block Lock protect serial
EEPROM memory in one package. This combination
ments, and increases reliability.
Applying power to the device activates the power on
reset circuit which holds RESET/RESET active for a
period of time. This allows the power supply and oscilla-
tor to stabilize before the processor can execute code.
The Watchdog Timer provides an independent protec-
tion mechanism for microcontrollers. When the micro-
controller fails to restart a timer within a selectable
time out interval, the device activates the RESET/
RESET signal. The user selects the interval from three
preset values. Once selected, the interval does not
change, even after cycling the power.
The device’s low V
user’s system from low voltage conditions, resetting
the system when V
CC
falls below the set minimum V
trip point. RESET/RESET is asserted until V
to proper operating level and stabilizes. Four industry
CC
detection circuitry protects the
