CDP1802AC datasheet



The CDP1802AC / CDP1803 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 / CDP1803 includes all of the circuits required for fetching, interpreting, and executing instructions which have been stored in standard typesof memories. Extensive input/output (I/O) control features are also provided to facilitate system design.


• Minimum Instruction Fetch-Execute Time of 4.5μs (Maximum Clock Frequency of 3.6MHz) at VDD = 5V, TA = +25°C

• Operation Over the Full Military, Temperature Range : -55°C to +125°C

• Any Combination of Standard RAM and ROM Up to 65,536 Bytes

• 8-Bit Parallel Organization With Bi-directional Data Bus and Multiplexed Address Bus

• 16×16 Matrix of Registers for Use as Multiple Program Counters, Data Pointers, or Data

• On-Chip DMA, Interrupt, and Flag Inputs

• High Noise Immunity : 30% of VDD
