DESCRIPTION
These devices combine three popular functions, Power-
on Reset Control, Supply Voltage Supervision, and Block
Lock Protect Serial EEPROM Memory in one pack-
age. This combination lowers system cost, reduces
board space requirements, 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 device’s low Vcc detection circuitry protects the
user’s system from low voltage conditions by holding
RESET/RESET active when Vcc falls below a minimum
Vcc trip point. RESET/RESET remains asserted until
Vcc returns to proper operating level and stabilizes. Five
industry standard V
TRIP
thresholds are available, how-
ever, Xicor’s unique circuits allow the thresold to be
reprogrammed to meet custom requirements or to fine-
tune the threshold in applications requiring higher preci-
sion.
