Hitachi HD66520T
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.| Part No. | HD66520T |

DESCRIPTION
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
