Top Searches for this datasheetINTEGRATED CIRCUIT µPD16667 160-OUTPUT DRIVER DESCRIPTION µPD16667 (common) driver which contains full-dot display. With outputs, this driver combined with column (segment) driver µPD16662 which contains display pixels pixels. With built-in display RAM, column driver reduce current consumption, thus making most suitable display area portable terminal. FEATURES LCD-driven voltage: Duty: 1/160 Driving type: lines selected simultaneously Output count: outputs Capable gray level display: gray levels (frame thinning-out) ORDERING INFORMATION Part Package (TAB) µPD16667N-XXX TCP's external shape custom-ordered. Therefore, have shape mind, please contact salesperson. information contained this document being issued advance production cycle device. parameters device change before final production Corporation, discretion, withdraw device prior production.

VDD, VEE, selected output selection control circuit. Selection control circuit This circuit creates signal which selects level output signal, based output shift register circuit driving level power selection signals Bidirectional shift register circuit This refers 80-bit bidirectional shift register circuit. signal used switch over shift direction. data that been entered from FRMB terminal shifted drive signal strobe (STB). Level shifter circuit This circuit transforms signals high-voltage signals liquid-crystal driving. µPD16667 FUNCTIONS Classification Power Name VCC1 FRMB DOFFB' Input/Output Function power level shifter power level shifter Power logic; liquid-crystal drive level power Power logic; liquid-crystal drive level power Liquid-crystal drive level power drive strobe signal Frame signal Display signal Drive level power selection signal (1st line) Drive level power selection signal (2nd line) Shift direction selection signal: when (DIR VEE), X160 when (DIR VDD), X160 Liquid-crystal drive output Selects outputs VDD, VEE, Liquid-crystal display timing Liquid-crystal drive output X160 DETAILS FUNCTIONS (input) Refers input drive strobe signal. bidirectional shift register shifted STB's rising edge. FRMB (input) Refers input frame signal. shift register data read STB's rising edge. (input) Refers input drive output's shift direction selection signal. When shift direction selection signal (DIR) "L", shift data (selection signal) shifted from drive output X160 direction. When "H", shifted from X160 direction. DOFFB' (input) Refers input display signal. placed display status (all outputs level. mean time, reads frame signal returns normal display status level. (input) Refer input pins drive level power selection signal. case liquid-crystal drive output, lines selected simultaneously shift register. selects first line, second line. Both lines select "H", "L". µPD16667 POWER SUPPLY SEQUENCE CHIP recommended apply power following sequence. VCC2 VCC1 input VDD, sure apply drive voltages last. VCC2 VCC1 Input (A0-A16, CSB, OEB, WEB, UBEB, D0-D15, DOFFB) more RESETB VCC2 more Note more Note more Note need turned same time. Turn power chip reverse sequence power application sequence.
