Description

The CDP1802 family of CMOS microprocessors are 8-bit

register oriented central processing units (CPUs) designed

for use as general purpose computing or control elements in

a wide range of stored program systems or products.

The CDP1802 types include 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 synchro-

nous interface to memories and external controllers for I/O

devices, and minimizes the cost of interface controllers. Fur-

ther, the I/O interface is capable of supporting devices oper-

ating in polled, interrupt driven, or direct memory access

modes.

The CDP1802A and CDP1802AC have a maximum input

CDP1802AC are functionally identical. They differ in that the

CDP1802A has a recommended operating voltage range of

4V to 10.5V, and the CDP1802AC a recommended operat-

ing voltage range of 4V to 6.5V.

The CDP1802BC is a higher speed version of the

CDP1802AC, having a maximum input clock frequency of

range of 4V to 6.5V.
