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.
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.
