HD44780U General Description

DescriptionThe HD66727, dot-matrix liquid crystal display controller and driver LSI incorporating a key scan function, displays alphanumerics, katakana, hiragana, and symbols. It can be configured to drive a dotmatrix liquid crystal display and control key scan functions under the control of an I2C bus or a clocksynchronized serial microprocessor. A single HD66727 is capable of displaying up to four 12-character lines, 40 segments, and 12 annunciators, and controlling up to a 4-by-8 key matrix, and driving three LED. The HD66727 incorporates all the functions required for driving a dot-matrix liquid crystal display such as display RAM, character generator, and liquid crystal drivers, and it also incorporates a booster for the LCD power supply and key scan functions.Features• Control and drive of a dot-matrix LCD with built-in key scan functions• Four 12-character lines, 40 segments, and 12 annunciators• Control of up to a 4 × 8-key matrix, 3 LED ports and 3 general ports• Low-power operation support: - 2.4 to 5.5V (low voltage) - Double or triple booster for liquid crystal drive voltage - Contrast adjuster and voltage followers for decreasing the direct current flow in the LCD drive bleeder-resistors - Standby mode and sleep mode - Displays up to 12 static annunciators• I2C bus or clock-synchronized serial interface• 60 × 8-bit display data RAM (60 characters max)• 11,520-bit character generator ROM - 240 characters (6 × 8 dots)• 32 × 6-bit character generator RAM - 4 characters (6 × 8 dots)• 8 × 6-bit segment RAM - 40 segment-icons and marks max• 60-segment × 34-common liquid crystal display driver• Programmable display sizes and duty ratios (see Table 1)• Vertical smooth scroll• Vertical double-height display of all character fonts• Horizontal double display with dedicated character fonts (6-dot font width used)• Wide range of instruction functions: - Clear display, display on/off control, icon and mark control, character blink, white-black inverting blinking cursor, icon and mark blink, return home, cursor on/off, white-black inverting raster-row• Internal oscillation with an external resistor• Hardware reset• Wide range of LCD drive voltages - 3.0V to 13.0V• Slim chip with bumps for chip-on-glass (COG) mounting, slim chip without bumps for chip-on-board (COB) mounting, and tape carrier package (TCP) (under development)
