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 posite 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 mon 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 posite 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), Standard ROM code Standard quad TCP (Conforms to EIAJ), Standard ROM code Standard dual TCP (Output OLB: 0.25 mm pitch), Standard ROM code µPD16435N-001- ××× µPD16435N-001-001 µPD16435N-001-002 µPD16435AN-001-××× µPD16435AN-001-001 µPD16435AN-001-052 Explanation of Part Number µPD16435 (A) N-xxx-xxx TCP code ROM code The TCP model is a custom model.
