HD66702
HD66702 is Dot-Matrix Liquid Crystal Display Controller/Driver manufactured by Hitachi Semiconductor.
Description The HD66702 dot-matrix liquid crystal display controller and driver LSI displays alphanumerics, Japanese kana characters, and symbols. It can be configured to drive a dot-matrix liquid crystal display under the control of a 4- or 8-bit microprocessor. Since all the functions required for driving a dot-matrix liquid crystal display are internally provided on one chip, a minimal system can be interfaced with this controller/driver. A single HD66702 can display up to two 20-character lines. The low 3-V power supply of the HD66702 under development is suitable for any portable battery-driven product requiring low power dissipation. Features - 5 × 7 and 5 × 10 dot matrix possible - 80 × 8-bit display RAM (80 characters max.) - 7,200-bit character generator ROM  160 character fonts (5 × 7 dot)  32 character fonts (5 × 10 dot) - 64 × 8-bit character generator RAM  8 character fonts (5 × 7 dot)  4 character fonts (5 × 10 dot) - 16-mon × 100-segment liquid crystal display driver - Programmable duty cycles  1/8 for one line of 5 × 7 dots with cursor  1/11 for one line of 5 × 10 dots with cursor  1/16 for two lines of 5 × 7 dots with cursor .. - Maximum display characters  One line 1/8 duty cycle, 20-char. × 1-line 1/11 duty cycle, 20-char. × 1-line  Two lines 1/16 duty cycle, 20-char. × 2-line - Wide range of instruction functions  Display clear, cursor home, display on/off, cursor on/off, display character blink, cursor shift, display shift - Choice of power supply (VCC): 4.5 to 5.5V (standard), 2.7 to 5.5V (low voltage) - Automatic reset circuit that initializes the controller/driver after power on (standard version only) - Independent LCD drive voltage driven off of the logic power supply (VCC): 3.0 to 8.3V - Low power dissipation - LQFP2020-144-pin, chip, chip wtith bump Ordering Information Type No. HCD66702RA00L HCD66702RA00BP HCD66702RA01L HCD66702RA02L HD66702RA00F HD66702RA00FL HD66702RA01F HD66702RA02F Package 144-pin-chip...
