DESCRIPTION
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 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.
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 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.
