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.
