UPD75512 Description
The µPD75512(A) is a 4-bit single-chip microputer which employs 75X series architecture, and its performance is parable to that of an 8-bit microputer. In addition to its high-speed processing capabilities, the µPD75512(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 µPD75512(A) provides the highest performance in its class.
