AUTOMOTIVE DIGITAL CLOCK IC

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.
