DESCRIPTION
The
μ
PD75316(A) is one of the 75X Series 4-bit single-chip microcomputer having a built-in LCD controller/
driver, and has a data processing capability comparable to that of an 8-bit microcomputer.
In addition to high-speed operation with 0.95
μ
s minimum instruction execution time for the CPU, the
μ
PD75316(A) can also process data in 1-, 4-, and 8-bit units. Therefore, as a 4-bit single-chip microcomputer
chip having a built-in LCD panel controller/driver, its data processing capability is the highest in its class in
the world.
Detailed functions are described in the following user's manual. Be sure to read it for designing.
