CDP1802AC/3

High-Reliability CMOS 8-Bit

Microprocessor

as a general purpose computing or control element in a wide

The CDP1802A/3 includes all of the circuits required for

fetching, interpreting, and executing instructions which have

been stored in standard types of memories. Extensive

input/output (I/O) control features are also provided to

facilitate system design.

The 1800 Series Architecture is designed with emphasis on

the total microcomputer system as an integral entity so that

systems having maximum flexibility and minimum cost can be

realized. The 1800 Series CPU also provides a synchronous

interface to memories and external controllers for I/O devices,

and minimizes the cost of interface controllers. Further, the I/O

interface is capable of supporting devices operating in polled,

The CDP1802AC/3 is functionally identical to its

predecessor, the CDP1802. The “A” version includes some

performance enhancements and can be used as a direct

replacement in systems using the CDP1802.
