FEATURES  
DESCRIPTION  
• Low Vcc Detection and Reset Assertion  
—Reset Signal Valid to Vcc=1V  
• Save Critical Data With Block LockTM Protection  
—Block LockTM Protect 0, 1/4, 1/2 or all of  
Serial E2PROM Memory Array  
• In Circuit Programmable ROM Mode  
• Long Battery Life With Low Power Consumption  
—<1µA Max Standby Current  
—<5mA Max Active Current during Write  
—<400µA Max Active Current during Read  
• 1.8V to 3.6V, 2.7V to 5.5V and 4.5V to 5.5V Power  
Supply Operation  
• 2MHz Clock Rate  
• Minimize Programming Time  
—32 Byte Page Write Mode  
—Self-Timed Write Cycle  
—5ms Write Cycle Time (Typical)  
• SPI Modes (0,0 & 1,1)  
These devices combines two popular functions, Supply  
Voltage Supervision and Serial E2PROM Memory in one  
package. This combination lowers system cost, reduces  
board space requirements, and increases reliability.  
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  
E2PROM array with Xicor’s Block LockTM Protection. The  
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.  
The device utilizes Xicor’s proprietary Direct WriteTM cell,  
providing a minimum endurance of 100,000 cycles per  
sector and a minimum data retention of 100 years.  
• Built-in Inadvertent Write Protection  
—Power-Up/Power-Down Protection Circuitry  
—Write Enable Latch  
—Write Protect Pin  
• High Reliability  
• Available Packages  
—14-Lead SOIC (X2564X)  
—14-Lead TSSOP (X2532X, X2516X)  
—8-Lead SOIC (X2532X, X2516X)
