Description
The IZ6451 is a dot matrix LCD (Liquid Crystal Display) drivers are designed for the
display of characters and graphics. The drivers generate LCD drive signals derived from
bit mapped data stored in an internal RAM. The IZ6451 which is able to drive 80 segments
for extention. The IZ6451 combine with IZ6570 drivers to expand the display capacity to
16 x 141 dots or 32 x 202 dots.

Notes: 1. All voltages are specified relative to VSS = 0V.
2. The following relation must be always hold VDD V2 V3 V5.
3. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage
to the device. These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
