CDP1823C/3

High-Reliability CMOS

128-Word x 8-Bit Static RAM

March 1997

Features

Description

• For Applications in Aerospace, Military, and Critical

Industrial Equipment

The CDP1823C/3 is a 128 word x 8-bit CMOS/SOS static

random access memory. It is compatible with the CDP1802,

CDP1804, CDP1805, and CDP1806 microprocessors, and

will interface directly without additional components. The

CDP1823C has a recommended operating voltage range of

4V to 6.5V.

• Compatible with CDP1800-Series Microprocessors at

Maximum Speed

• Interfaces with CDP1800-Series Microprocessors

without Additional Components

The CDP1823C memory has 8 common data input and data

output terminals for direct connection to a bidirectional data

bus and is operated from a single voltage supply. Five chip

select inputs are provided to simplify memory system

expansion. In order to enable the CDP1823C, the chip select

inputs CS2, CS3, and CS5 require a low input signal, and

the chip select inputs CS1 and CS4 require a high input

signal.
