1 / 94 page  ST Sitronix ST7626 65K Color Dot Matrix LCD Controller/Driver Ver 1.5 1/94 2007/01/20 1. INTRODUCTION The ST7626 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 294 Segment and 68 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI) or 8-bit/16-bit parallel display data and stores in an on-chip display data RAM. It performs display data RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components. 2. FEATURES Driver Output Circuits ♦ 294 Segment Outputs / 68 Common Outputs Applicable Duty Ratios ♦ Various Partial Display ♦ Partial Window Moving & Data Scrolling Gray-Scale Display ♦ 4FRC & 31 PWM function circuit to display ♦ 64 gray-scale display. On-chip Display Data RAM ♦ Capacity: 98 x 68 x 16 =106,624 bits ♦ 4K colors (RGB)=(444) mode ♦ 65K colors (RGB)=(565) mode ♦ Truncated 262K colors (RGB)=(666) mode ♦ Truncated 16M colors (RGB)=(888) mode Microprocessor Interface ♦ 8/16-bit parallel bi-directional interface with 6800-series or 8080-series ♦ 4-line serial interface (4-line-SIF) ♦ 3-line serial interface (3-line-SIF) On-chip Low Power Analog Circuit ♦ On-chip Oscillator Circuit ♦ On-chip Voltage Converter (x2, x3, x4, x5) with internal booster capacitors. ♦ Extremely Few Outsider Compoment. (Minimum required outsider compoments: One Capacitor). ♦ On-chip Voltage Regulator (Temperature gradient = -0.065%/°C) ♦ On-chip Electronic Contrast Control Function (406 steps) ♦ Voltage Follower (LCD bias: 1/5 to 1/12) Operating Voltage Range ♦ Supply Digital Voltage (VDD, VDD1): 1.8 to 3.3V ♦ Supply Analog Voltage (VDD2, VDD3, VDD4, VDD5): 2.4 to 3.3V ♦ LCD Driving Voltage (VOP = V0 - VSS): 3.76V to 18V ♦ The suggested value of V0 is under 11 V with bias =1/9. LCD Driving Voltage (EEPROM) ♦ Contrast Adjustment Value is stored in the Built-In EEPROM for better display quility. LCM Performance Adjustment (EEPROM) ♦ Adjustment Value for best Display Performance is stored in the Built-In EEPROM. Package Type ♦ Application for COG ST7626 6800 , 8080 ,4-Line , 3-Line interface |
