PD75512(A)
4-BIT SINGLE-CHIP MICROCOMPUTER
DESCRIPTION
The
碌
PD75512(A) is a 4-bit single-chip microcomputer which employs 75X series architecture, and its
performance is comparable to that of an 8-bit microcomputer.
In addition to its high-speed processing capabilities, the
碌
PD75512(A) 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
碌
PD75512(A) provides
the highest performance in its class.
Detailed functions are described in the following user鈥榮 manual. Be sure to read it for designing.
