DESCRIPTION
These devices combines two popular functions, Supply
Voltage Supervision and Serial E
package. This combination lowers system cost, reduces
board space requirements, and increases reliability.
2
PROM Memory in one
The user’s system is protected from low voltage condi-
tions by the devices low Vcc detection circuitry. When
Vcc falls below the minimum Vcc trip point, the system is
reset. RESET/RESET is asserted until Vcc returns to
proper operating levels and stabilizes.
The memory portion of the device is a CMOS Serial
E
PROM array with Xicor’s Block Lock
array is internally organized as x 8. The device features a
Serial Peripheral Interface (SPI) and software protocol
allowing operation on a simple four-wire bus.

Protection. The
The device utilizes Xicor’s proprietary Direct Write
providing a minimum endurance of 100,000 cycles per
sector and a minimum data retention of 100 years.
