SD42C/P1008
4Bit Single Chip Microcontroller
Description
The SD42C1008 is a microcomputer of the 4-bit single chip microcomputer SD42xx series
which can match an 8-bit microcomputer in the data processing capability.
The SD42C1008 can handle 1-bit, 4-bit, and 8-bit data as well as operates at high speed
(minimum instruction execution time : 0.95us) it contains a LCD pannel controller/driver.
