ST7026 Datasheet | Sitronix

Sitronix 48 x 4 Dots Segment-type LCD Controller/Driver 1. INTRODUCTION ST7026 is a LCD driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 48 segment and 4 mon driver circuits. ST7026 can be connected directly to a microprocessor with 3-Line serial peripheral interface (3-SPI) or I2C patible interface. Display data written by MPU is stored in an on-chip Display Data RAM (DDRAM) of 48 x 4 bits. ST7026 performs Display Data RAM write-operation without external clock to minimize power consumption. In addition, the built-in LED backlight control circuit can setup an LED backlight system with minimal ponents if necessary. 2.
