DESCRIPTION
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 LCDdrive bleeder-resistors. The HD66704 has a slim-chip configuration and interface-signal alignment that make it appropriate for chipon-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.FEATURES
