HD66108
(RAM-Provided 165-Channel LCD Driver for Liquid Crystal Dot
Matrix Graphics)
ADE-207-278(Z)
'99.9
Rev. 0.0
Description
The HD66108 under control of an 8-bit MPU can drive a dot matrix graphic LCD (liquid-crystal display)
employing bit-mapped display with support of an 8-bit MPU.
Use of the HD66108 enables a simple LCD system to be configured with only a small number of chips,
since it has all the functions required for driving the display.
The HD66108 also enables highly-flexible display selection due to the bit-mapped method, in which one
bit of data in a display RAM turns one dot of an LCD panel on or off. A single HD66108 can display a
maximum of 100
×
65 dots by using its on-chip 165
×
65-bit RAM. Also, by using several HD66108’s, a
display can be further expanded.
The HD66108 employs the CMOS process and TCP package. Thus, if used together with an MPU, it can
provide the means for a battery-driven pocket-size graphic display device utilizing the low current
consumption of LCDs.
