The CDP1824/3 and CDP1824C/3 types are high-reliability  
CMOS 32-word x 8-bit fully static random-access memories  
for use in CDP1800-series microprocessor systems. These  
parts are compatible with the CDP1802 microprocessor and  
will interface directly without additional components.

• No Precharge or Clock Required  
The CDP1824/3 is fully decoded and does not require a pre-  
charge or clocking signal for proper operation. It has com-  
mon input and output and is operated from a single voltage  
supply. The MRD signal (output disable control) enables the  
three-state output drivers, and overrides the MWR signal. A  
CS input is provided for memory expansion.

The CDP1824C/3 is functionally identical to the CDP1824/3.  
The CDP1824/3 has a recommended operating voltage  
range of 4V to 10.5V, and the CDP1824C/3 has an operating  
voltage range of 4V to 6.5V.
