DESCRIPTION
The
µ
PD75512 is a 4-bit single-chip microcomputer which employs 75X series architecture, and its perform-
ance is comparable to that of an 8-bit microcomputer.
In addition to its high-speed processing capabilities, the
µ
PD75512 is also capable of processing data in units
of 1, 4, or in 8-bits. With its internally provided A/D converter and serial interface, the
µ
PD75512 provides the
highest performance in its class.
Detailed functions are described in the following user‘s manual. Be sure to read it for designing.
