1 / 160 page  ST Sitronix ST7625 65K Color Dot Matrix LCD Controller/Driver Ver 1.6 1/160 2008/07 1. INTRODUCTION The ST7625 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 306 Segment and 96 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 ♦ 306 Segment Outputs / 96 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 ♦ Support 8 color mode (Idle mode) On-chip Display Data RAM ♦ Capacity: 102 x 96 x 16 =156,672 bits Color support by Interface ♦ 256 color mode, (RGB)=(332) mode ♦ 4K color mode, (RGB)=(444) mode ♦ 65K color mode, (RGB)=(565) mode ♦ Truncated 262K color mode, (RGB)=(666) mode ♦ Truncated 16M color mode, (RGB)=(888) mode Microprocessor Interface ♦ 8/16-bit parallel bi-directional interface with 6800-series or 8080-series ♦ 4-line serial interface ♦ 3-line (9-bits) serial interface On-chip Low Power Analog Circuit ♦ On-chip Oscillator Circuit ♦ On-chip Voltage Converter (x2, x3, x4, x5, x6, x7, X8) with internal booster capacitors. ♦ Extremely Few Outsider Components. (Required outsider components: Three Capacitors) ♦ On-chip Voltage Regulator ♦ On-chip Electronic Contrast Control Function ♦ Voltage Follower (LCD bias: 1/5~1/12) Operating Voltage Range ♦ Supply Digital Voltage (VDD, VDD1): 1.65 to 3.0V ♦ Supply Analog Voltage (VDD2, VDD3, VDD4, VDD5): 2.4 to 3.3V ♦ LCD Driving Voltage (VOP = V0 - VSS): Max to 18V LCD Driving Voltage (OTP) ♦ Contrast Adjustment Value is stored in the Built-In OTP-ROM for better display quality. LCD Driving setting suggestion ♦ VOP = 11V, BIAS=1/9.
