UPD16667

DATA SHEET MOS INTEGRATED CIRCUIT µPD16667 160-OUTPUT LCD ROW DRIVER The µPD16667 is a row (common) driver which contains a RAM capable of full-dot LCD display. With 160 outputs, this driver can be combined with a column (segment) driver, µPD16662, which contains a RAM to display 240 × 160 pixels to 480 × 320 pixels. With a built-in display RAM, the column driver can reduce the current consumption, thus making it most suitable for the display block of a PDA or portable terminal. FEATURES LCD-driven voltage: 20 to 36 V Duty: 1/160 Driving type: 2 lines selected simultaneously Output count: 160 outputs Capable of gray scale display: 4 gray scales ORDERING INFORMATION Part No. Package TCP (TAB) Standard TCP (OLB: 0.2 mm pitch, folding) µPD16667N-XXX µPD16667N-051 The external shape of the TCP is custom-made, so please contact an NEC sales representative with your shape requirements.
