Description  
• Maximum Input Clock Maximum Frequency Options  
At VDD = 5V  
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.

• Maximum Input Clock Maximum Frequency Options  
At VDD = 10V  
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 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.

• Any Combination of Standard RAM and ROM Up to  
65,536 Bytes  
• 8-Bit Parallel Organization With Bidirectional Data Bus  
and Multiplexed Address Bus  
• 16 x 16 Matrix of Registers for Use as Multiple  
Program Counters, Data Pointers, or Data Registers  
The CDP1802A and CDP1802AC have a maximum input  
clock frequency of 3.2MHz at VDD = 5V. The CDP1802A and  
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.  
• On-Chip DMA, Interrupt, and Flag Inputs  
• Programmable Single-Bit Output Port  
• 91 Easy-to-Use Instructions  
The CDP1802BC is  
a higher speed version of the  
CDP1802AC, having a maximum input clock frequency of  
5.0MHz at VDD = 5V, and a recommended operating voltage  
range of 4V to 6.5V.
