CDP1821C Overview
The CDP1821C/3 is a 1024-word x 1-bit CMOS silicon-on-sapphire (SOS), fully static, random-access memory designed for use in CDP1800 microprocessor systems. This device has a remended operating voltage range of 4V to 6.5V. The output state of the CDP1821C/3 is a function of the input address and chip-select states only.
