TECHNICAL DATA
AUTOMOTIVE DIGITAL CLOCK IC
DESCRIPTION
KK7100
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.
