Description

The CDP1824 and CDP1824C are 32-word x 8-bit fully static CMOS random-access memories for use in CDP-1800 series microprocessor systems. These parts are compatible with the CDP1802 microprocessor and will interface directly without additional components.
The CDP1824 is fully decoded and does not require a precharge or clocking signal for proper operation. It has common 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 is functionally identical to the CDP1824.
The CDP1824 has an operating range of 4V to 10.5V, and the CDP1824C has an operating voltage range of 4V to 6.5V. The CDP1824 and CDP1824C are supplied in 18 lead hermetic dual-in-line ceramic packages (D suffix), and in 18 lead dual-in-line plastic packages (E suffix).
