Description
NT7651
PRELIMINARY Features
! Single-chip LCD controller/driver ! 2-line display of up to 16 characters + 160 icons, 1-line display of up to 32 characters + 160 icons, or 1-line display of up to 16 characters + 80 icons ! 5 × 7 character format plus cursor; 5 × 8 for user defined symbols ! Icon mode: Reduced current consumption while displaying icons only ! On-chip: DC-DC converter generation of LCD supply voltage, independent of VDD Temperature compensation of on-chip generated VLCD: -8 tο -12 mV/K at 5.0 V (programmable by instruction) Generation of intermediate LCD bias voltages Oscillator requires no external components (external clock also possible). ! Versatile display functions provided on chip: Clear display, Return home, Entry mode set, Display control, Cursor /display shift, Character blink, Icon blink, Screen configuration, Icon display control. ! Character Generator ROM: 240 characters (240 × 5 × 8 bits). ! Character Generator RAM: 16 characters (16 × 5 × 8 bits); 4 characters used to drive 160 icons, 8 characters used if icon blink feature is used in application. ! Display Data RAM: 80 characters (80 × 8 bits) ! 18 common and 80 segment outputs ! Three duty factors selected by program: 1/2 duty for icon only mode 1/9 duty for single line operation 1/18 duty for normal operation ! Logic supply voltage range: Chip may be driven with two battery cells. VDD1 = 1.5 to 3.5 V ! High voltage generator supply voltage range: VDD2 = 2.2 to 3.5V...
