Description
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.
The MRD signal enables all 8 output drivers when in the low
state and should be in a high state during a write cycle.
After valid data appear at the output, the address inputs may
be changed immediately. Output data will be valid until either
the MRD signal goes high, the device is deselected, or t
AA
(access time) after address changes.
