General Description
The ISL12058 device is a low power real time clock with
clock/calendar, and alarm.
The oscillator uses an external, low-cost 32.768kHz crystal.
The real time clock tracks time with separate registers for
hours, minutes, and seconds. The device has calendar
registers for date, month, year and day of the week. The
calendar is accurate through 2099, with automatic leap year
correction.
The ISL12058's flexible alarm can be set to any
clock/calendar value for a match. For example, every
minute, every Tuesday or at 5:23 AM on March 21. The
alarm status is available by checking the Status Register, or
the device can be configured to provide a hardware interrupt
via the IRQ/FOUT pin.
Pin Descriptions
X1, X2
The X1 and X2 pins are the input and output, respectively, of
an inverting amplifier. An external 32.768kHz quartz crystal
is used with the ISL12058 to supply a timebase for the real
time clock. Refer to Figure 6.
The device can also be driven directly from a 32.768kHz
square wave source with peak to peak voltage from 0V to
VDD at X1 pin with X2 pin floating.
Typical Performance Curves Temperature is +25°C unless otherwise specified
