eet4UDESCRIPTION
taShThe DMC42C1008 is a microcomputer of the 4-bit single chip
amicrocomputer DMC42xx series which can match an 8-bit
.Dmicrocomputer in the data processing capability.
wThe DMC42C1008 can handle 1-bit, 4-bit, and 8-bit data
was well as operates at high speed (minimum instruction
wexecution time : 0.95us) it contains a LCD pannel controller/driver.
