Preliminary

HD66704

(Graphics LCD Controller/Driver

with Two 16-Character Lines and 160 Segments)

Rev 1.0

August 29, 2000

Description

The HD66704 LCD controller and driver LSI is used to display alphanumeric characters, katakana,

hiragana, a variety of symbols, and seven-segment numerals. It can be connected to a high-performance

microcomputer via a high-speed clock-synchronized serial connection or on a four-bit bus. The

HD66704 is capable of displaying two 16-character lines and 160 segments or one 16-character line and

240 segments in its character mode. The HD66704 has 432 built-in fonts for character display and

supports double-height display. In its segment mode, it can drive up to 320 segments (at a duty cycle of

1/4). Segment-by-segment control of a blinking state, as well as the on/off state, is available.

The HD66704 applies various techniques for reducing the power consumption of an LCD system. These

include low-voltage operation at 1.8 V or less, a booster to generate a maximum of triple the LCD-drive

voltage from the supplied voltage, and voltage-followers to decrease the flow of direct current into the

LCD-drive bleeder-resistors.

The HD66704 has a slim-chip configuration and interface-signal alignment that make it appropriate for

chip-on-glass (COG) mounting. It is suitable for any product in which an LCD display may be used,

such as facsimiles, telephones, pagers, audio equipment, video tape recorders, and electronic wallets.
