UPD16435A

DATA SHEET µPD16435, 16435A DOT MATRIX LCD CONTROLLER/DRIVER MOS INTEGRATED CIRCUIT DESCRIPTION The µPD16435 and 16435A are controllers/drivers for a 119 × 73-dot LCD, and perform LCD full-dot and character composite display by means of control by a microprocessor that has a 4 or 8-bit data bus. A charge pump type DC/DC converter is also incorporated, enabling 3 or 5 V single power supply drive. The µPD16435 uses an external reference clock. The µPD16435A has the on-chip oscillation circuit (external crystal resonator). FEATURES Can interface to 4 or 8-bit CPU. Incorporates 119 segment outputs and 73 common outputs. (Display duty selectable from 1/35, 1/37, 1/71, 1/73) 5 × 7 character font 208 character data configuration character generation ROM and 16 character data configuration character generation RAM, allowing composite full-dot and character display Incorporates extended display functions such as magnification, lateral scrolling, blink, reverse, etc. Operating voltage: 2.7 V to 5.5 V On-chip DC/DC converter: Selectable between ×4 set-up circuit and ×2 step-up circuit On-chip temperature correction circuit Master/slave operation capability On-chip power-on reset circuit On-chip oscillation circuit (µPD16435A) 232-pin TCP (Tape Carried Package) ORDERING INFORMATION Part Number Package TCP (TAB), Standard ROM code Standard quad TCP (Conforms to EIAJ), Standard ROM code Standard dual TCP (Output OLB: 0.25 mm pitch), Standard ROM code TCP (TAB), S...
