µPD16662
240 OUTPUT LCD COLUMN (SEGMENT) DRIVER WITH BUILT-IN RAM
The µPD16662 is a column (segment) driver which contains a RAM capable of full dot LCD drive.
With 240 outputs, this driver has a display RAM of 240 x 160 x 2 bits built in, and 4 gray scales of display are
possible. Any 4 gray scales can be selected from 25 levels of the gray scale pallet. The driver can be combined
with the µPD16667 to display from 240 x 160 dots to 480 x 320 dots.
Features
Display RAM incorporated: 240 x 160 x 2 bits
Logic voltage: 3.0V to 3.6V
Duty: 1/160
Output count: 240 outputs
Capable of gray scale display: 4 gray scales (can be selected from 25 levels of the gray scale pallet)
Memory management: packed pixel system
8/16-bit data base

For the access from the system to be performed in units of words (16 bits), or of bytes (8 bytes), the /UBE (high
byte enable) and A0 are used to show whether valid data are in the bytes of either (or both) of D0 to D7 and D8 to
D15.
