General Description
The ISL12022M device is a low power real time clock (RTC) with
embedded temperature sensor and crystal. It contains crystal
frequency compensation circuitry over the operating temperature
range good to ±5ppm accuracy. It also contains a clock/calendar
with Daylight Savings Time (DST) adjustment, power fail and low
battery monitors, brownout indicator, 1 periodic or polled alarm,
intelligent battery backup switching and 128 Bytes of battery-
backed user SRAM.
The oscillator uses an internal 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. In addition, the ISL12022M
can be programmed for automatic Daylight Saving Time (DST)
adjustment by entering local DST information.
The ISL12022M’s 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. There is a repeat mode for
the alarm allowing a periodic interrupt every minute, every hour,
every day, etc.
The device also offers a backup power input pin. This VBAT pin
allows the device to be backed up by battery or supercapacitor
with automatic switchover from VDD to VBAT. The ISL12022M
device is specified for VDD = 2.7V to 5.5V and the clock/calendar
portion of the device remains fully operational in battery backup
mode down to 1.8V (Standby Mode). The VBAT level is monitored
and reported against preselected levels. The first report is
registered when the VBAT level falls below 85% of nominal level;
the second level is set for 75%. Battery levels are stored in
PWR_VBAT registers.
The ISL12022M offers a “Brownout” alarm once the VDD falls
below a pre-selected trip level. This allows system Micro to save
vital information to memory before complete power loss. There are
six VDD levels that could be selected for initiation of the Brownout
alarm.
