LCD Segment Drivers
Multi-function LCD Segment Drivers
BU97600xxx Series
MAX 148 Segment(37SEG x 4COM)
General Description
The BU97600FV-M and BU97600FUV-M are 1/4,
1/3, 1/2 or 1/1 duty general-purpose LCD driver.
The BU97600FV-M and BU97600FUV-M can also
control up to 16 general-purpose output ports.
These products also incorporate a key scan circuit
that accepts input from up to 20 keys to reduce
printed circuit board wiring.
Features
„ AEC-Q100 Qualified ^(Note1)
„ Key input function for up to 20 keys (A key scan
is performed only when a key is pressed.)
„ Either 1/4, 1/3, 1/2 or 1/1 duty (static) can be
selected with the serial control data.
„ Serial data control of frame frequency for
common and segment output waveforms.
„ Serial data control of switching between the
segment output ports, PWM output port and
general-purpose output port functions.
(Max 6ch internal PWM, max 16ch external PWM
and max16ch GPO.)
