CDP1823C/3
March 1997
High-Reliability CMOS 128-Word x 8-Bit Static RAM
Description
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. 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.
