HM17CM256
Preliminary Specification(0.3)
128XRGBX82 OUTPUT LCD DRIVER IC
s INSTRUCTION
with built-in RAM
HM17CM256 is a dot-Matrix LCD drive IC with 82
commons (80 + 2 icons) and 384 segments (128 X
RGB) drive ports for 256 colors driving.
This IC stores the serial or parallel BIT data
transferred by the microcomputer on the built-in
RAM (81,920 bits for graphic + 2048 bits for icons)
and generates the signals to drive LCD panel.
Color graphic display is achieved by selecting 8
gray (256 color) 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 164 x 128 display (maximum) is possible with
master and slave application.
