65K Color Dot Matrix LCD Controller/Driver

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.

♦ On-chip Voltage Converter (x2, x3, x4, x5) with internal

2. FEATURES

booster capacitors.

Driver Output Circuits

♦ 294 Segment Outputs / 68 Common Outputs

Applicable Duty Ratios

♦ Extremely Few Outsider Compoment. (Minimum required

outsider compoments: One Capacitor).

♦ On-chip Voltage Regulator (Temperature gradient =

-0.065%/°C)

♦ Various Partial Display

♦ Partial Window Moving & Data Scrolling

Gray-Scale Display

♦ On-chip Electronic Contrast Control Function (406 steps)

♦ Voltage Follower (LCD bias: 1/5 to 1/12)

Operating Voltage Range

♦ 4FRC & 31 PWM function circuit to display

♦ 64 gray-scale display.

On-chip Display Data RAM

♦ Supply Digital Voltage (VDD, VDD1): 1.8 to 3.3V

♦ Supply Analog Voltage (VDD2, VDD3, VDD4, VDD5): 2.4

to 3.3V

♦ 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

♦ 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.

♦ 8/16-bit parallel bi-directional interface with 6800-series

or 8080-series

LCM Performance Adjustment (EEPROM)

♦ Adjustment Value for best Display Performance is stored

in the Built-In EEPROM.

♦ 4-line serial interface (4-line-SIF)

♦ 3-line serial interface (3-line-SIF)

On-chip Low Power Analog Circuit

♦ On-chip Oscillator Circuit

Package Type

♦ Application for COG
