DESCRIPTION  
The powerful Dual Alarms can be set to any  
Clock/Calendar value for a match. For instance, every  
minute, every Tuesday, or 5:23 AM on March 21. The  
alarms can be polled in the Status Register or provide a  
hardware interrupt (IRQ Pin). There is a repeat mode for  
the alarms allowing a periodic interrupt.  
The X1288 device is a Real Time Clock with  
clock/calendar, two polled alarms with integrated 32kx8  
EEPROM, oscillator compensation, CPU Supervisor  
(POR/LVS and WDT) and battery backup switch.  
The oscillator uses an external, low-cost 32.768kHz  
crystal. All compensation and trim components are  
integrated on the chip. This eliminates several external  
discrete components and a trim capacitor, saving board  
area and component cost.  
The PHZ/IRQ pin may be software selected to provide a  
frequency output of 1 Hz, 100 Hz, or 32,768 Hz.  
The X1288 device integrates CPU Supervisor func-tions  
and a Battery Switch. There is a Power-On Reset  
(RESET output) with typically 250 ms delay from power-  
on. It will also assert RESET when Vcc goes below the  
specified threshold. The Vtrip threshold is user repro-  
grammable. There is a WatchDog Timer (WDT) with 3  
selectable time-out periods (0.25s, 0.75s, 1.75s) and a  
disabled setting. The watchdog activates the RESET pin  
when it expires.  
The Real-Time Clock keeps track of time with separate  
registers for Hours, Minutes, Seconds and 1/100 of a  
second. The Calendar has separate registers for Date,  
Month, Year and Day-of-week. The calendar is correct  
through 2099, with automatic leap year correction.
