HD66522
(160-Channel Column Driver with Internal Bit-Map RAM for
Reflective Color Display and Grayscale Display)
ADE-207-302(Z)
'99.9
Rev. 0.0
Description
The HD66522 is a column driver for liquid crystal dot-matrix graphic display system. This LSI
incorporates 160 liquid crystal drive circuit and a 160 * 240 * 2-bit bit-mapped 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 MPU. The HD66522 also has a new arbitration
method which prevents flicker when the MPU performs draw access asynchronously. The on-chip display
RAM greatly decreases power consumption compared to previous liquid crystal display system because
there is no need for high speed data transfer. The chip also incorporates a four-level grayscale out of 32-
level grayscale palette controller for enhanced graphics capabilities and reflective color.
