LC79401KNE: Dot-Matrix LCD Driver
The LC79401KNE is a 80-outputs segment driver LSI for graphic dot-matrix liquid crystal display systems. The LC79401KNE latches 80 bits of display data sent from a controller using a 4-bit parallel transfer technique and generates LCD drive signals. When combined as a kit with common driver, either the LC79430KNE (QIP100E), the LC79401KNE can drive large screen LCD panels.
Features- Incorporates LCD drive circuits for 80 bits of display.
- Supports display duties from 1/64 to 1/256
- The provision of a chip disable pin supports power reduction in large-scale panels.
- Allows external provision of the bias power supply
- Operating supply voltage/operating temperature
- Data transfer clock : 6.0MHz (max), bidirectional shifting supported
- Data input : 4-bit parallel input
