4-BIT SINGLE-CHIP MICROCOMPUTER

DESCRIPTION

The

PD75516 is a product in the 75X series(of 4-bit single-chip microcomputers). The 75X series has an

architecture which is comparable to that of 8-bit microcomputers.

The

PD75516 possesses high class processing capacities as a 4-bit single-chip microcomputer with built-in

A/D converter and serial interface, including the capability to process data in lengths of 1, 4 and 8 bits in addition

to its high speed operation.

Details of functions are described in the User's Manual shown below. Be sure to read in design.

PD75516 User's Manual: IEM–5049

FEATURES
