General Description
The HT0610 is a driver and controller LSI for graphic
dot-matrix liquid crystal display systems. It has 33 com-
mon and 120 segment driver circuits. This chip is con-
nected directly to an MCU, accepts 8-bit parallel display
data and stores an on-chip graphic display data RAM
(BGDRAM) of 33´120 bits. It provides a high-flexible
display section due to the one-to-one correspondence

between BGDRAM bits and LCD panel pixels. It per-
forms BGDRAM read/write operation with no externally
operating clock to minimize power consumption. In ad-
dition, because it contains power supply circuits neces-
sary to drive an LCD, it is possible to make a display
system with minimal components.
