OKI offers a new family of ultra-low power
Real
Time Clocks based on SOI (*) technology.
This technology allows very low
power
operation devices with optimized power
consumption.
The ML9073 and ML9074
are real time
clock LSIs optimized for low
voltage and low current
consumption.
The time/date provides second, minute,
hour, day, week,
month and year |
|
|
information. The clock operates in either 24-hour and 12-hour
format. In addition to its
clock and calendar functions, the
ML9073/ML9074 enables 30 seconds adjustment,
fixed period
interrupt and start/stop functions. All address and data are
transferred
serially through a 2-line (I2C) bus or 3-line bus.
See the chart for comparison of OKI´s new RTC family
ML9073 and ML9074 with |
major competitors, the OKI SOI
advantage in power consumption is
very
attractive for your new design
It offers you a more than 1.5
fold
longer battery life than conventional devices.
