HD66421
System Description
The HD66421 can display a maximum of 160 x
100 dots (ten 16x16-dot characters x 6 lines)
four-level gray scale or four colour LCD panel.
Four levels of gray scale can be selected from
32-levels, so the appropriate 4-level gray scale can
be displayed. And Monochrome display can be
selected from two planes. One plane is displayed
while the other plane is being written. The
HD66421 can reduce power dissipation without
affecting display because data is retained in the
display RAM even during standby modes. An
LCD system can be configured simply by
attaching external power supply, capacitors and
resistors
