HM17CM4096
Preliminary Specification
128XRGBX162 OUTPUT LCD DRIVER IC
with built-in RAM
s
INSTRUCTION
HM17CM4096
is a dot-Matrix LCD drive IC with
162 commons and 384 segments (128 X RGB) drive
ports for 4,096 colors driving.
This IC stores the serial or parallel BIT data
transferred by the microcomputer on the built-in
RAM (248,832 bits for graphic) and generates the
signals to drive LCD panel.
Color graphic display is achieved by selecting 16
gray (16R
16G
16B = 4,096 color or 256
color mode ) levels out of 32 gray palettes
independently.
This IC is suitable for battery-operated system,
hand-carrying information equipment by ensuring
low power consumption, low power supply (1.7V ~ )
and a wide range of operating voltage.
And 162 x 128 display is possible with just one
chip.
