HD66108
(RAM-Provided 165-Channel LCD Driver for Liquid Crystal Dot
Matrix Graphics)
Description
The HD66108T 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 HD66108T 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 HD66108T 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 HD66108T can
display a maximum of 100 × 65 dots by using its on-chip 165 × 65-bit RAM. Also, by using several
HD66108T’s, a display can be further expanded.
The HD66108T 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.
