Programmable Watchdog Timer w/Serial E2PROM  
FEATURES  
DESCRIPTION  
• Programmable Watchdog Timer with Reset  
Assertion  
—Reset Signal Valid to Vcc=1V  
—Power Up Reset Control  
These devices combine two popular functions, Watchdog  
Timer, and Serial E2PROM Memory in one package.This  
combination lowers system cost, reduces board space  
requirements, and increases reliability.  
• 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  
—<50µA Max Standby Current, Watchdog On  
—<1µA Max Standby Current, Watchdog Off  
—<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)  
The Watchdog Timer provides an independent protection  
mechanism for microcontrollers. During a system failure,  
the device will respond with a RESET/RESET signal  
after a selectable time-out interval. The user selects the  
interval from three preset values. Once selected, the  
interval does not change, even after cycling the power.  
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)
