128-word X 8-bit Lsi Static Ram Corporation

The CDP1823 and CDP1823C are 128-word by 8-bit CMOS SOS static random-access Memories These Memories are compatible with general-purpose Microprocessors The two Memories are functionally identical. They differ in that the CDP1823 has a recommended operating voltage range of 4V to 10.5V, and the CDP1823C has a recommended oper- ating voltage range of 4V to 6.5V. The CDP1823 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 expan- sion. In order to enable the CDP1823 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. By Intersil Corporation
