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.

DIP-40

FEATURES

• 4.194304 MHz crystal oscillator
