The CDP1802A/3 High-Reliability LSI CMOS 8-bit register
oriented Central-Processing Unit (CPU) is designed for use
as a general purpose computing or control element in a wide
range of stored-program systems or products.
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 facili-
tate 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,
interrupt-driven, or direct memory-access modes.
The CDP1802AC/3 is functionally identical to its predeces-
sor, the CDP1802. The “A” version includes some perfor-
mance enhancements and can be used as a direct
replacement in systems using the CDP1802.
This type is supplied in 40 lead dual-in-line sidebrazed
ceramic packages (D suffix).
