HD66520T  
(160-Channel 4-Level Grayscale Display Column Driver with  
Internal Bit-Map RAM)  
Description  
The HD66520 is a column driver for liquid crystal dot-matrix graphic display systems. This LSI  
incorporates 160 liquid crystal drive circuits and a 160 × 240 × 2-bit bit-map RAM, which is suitable for  
LCDs in portable information devices. It also includes a general-purpose SRAM interface so that draw  
access can be easily implemented from a general-purpose CPU. The HD66520 also has a new arbitration  
method which prevents flicker when the CPU performs draw access asynchronously. The on-chip display  
RAM greatly decreases power consumption compared to previous liquid crystal display systems because  
there is no need for high-speed data transfer. The chip also incorporates a four-level grayscale controller  
for enhanced graphics capabilities, such as icons on a screen.  
Features  
Duty cycle: 1/64 to 1/240  
Liquid crystal drive circuits: 160  
Low-voltage logic circuit: 3.0 to 5.5-V operation power supply voltage  
High-voltage liquid crystal drive circuit: 8 to 28-V liquid crystal drive voltage  
Grayscale display: FRC four-level grayscale display  
Grayscale memory management: Packed pixel  
Internal bit-map display RAM: 76800 bits (160 × 240 lines × two planes)  
CPU interface  
SRAM interface  
Address bus: 16 bits, data bus: 8 bits
