HD66420 - (RAM-Provided 160 Channel 4-Level Grey Scale Driver for Dot Matrix Graphics LCD)

General Description

The HD66420 drives and controls a dot matrix graphic LCD(Liquid Crystal Display) using a bit-mapped method.

It provides a highly flexible display through its on-chip display RAM, in which each two bits of data can be used to turn on or off one dot on LCD panel with four-level grey scale.

Key Features

  • Built-in bit-mapped display RAM: 25.6kbits (160 × 80 × 2 bits) Grey scale display: PWM four-level grey scale can be selected from 32 levels Grey scale memory management: Packed pixel Partial display: Eight-lines data can be displayed in any place An 80-system MPU interface Power supply voltage for operation : 2.2V to 5.5V Power supply voltage for LCD : 13 V max. Selectable multiplex duty ratio: 1/.

HD66420 (RAM-Provided 160 Channel 4-Level Grey Scale Driver for Dot Matrix Graphics LCD) Description The HD66420 drives and controls a dot matrix graphic LCD(Liquid Crystal Display) using a bit-mapped method. It provides a highly flexible display through its on-chip display RAM, in which each two bits of data can be used to turn on or off one dot on LCD panel with four-level grey scale. A single HD66420 can display a maximum of 160x80 dots using its powerful display control functions. It can display only eight lines out of eighty lines. This function realize low power consumption because high voltage for driving LCD is not needed. An MPU can access HD66420 at any time, because the MPU operations are asynchronous with the HD66420’s system clock and display operation.
