TECHNICAL DATA
AUTOMOTIVE DIGITAL CLOCK IC
IN7100
DESCRIPTION
IN7100 is a automotive digital clock, CMOS LSI.
It drives fluorescent indicator panel directly. It can
be driven by a 4.194304 MHz crystal oscillator or
an external clock signal (1024 Hz). It has 4-ways
display brightness control function and its display
format is 12 hours.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
