Description
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.
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.
