The AT28C64 is a low-power, high-performance 8,192 words by 8-bit nonvolatile electrically erasable and programmable read only memory with popular, easy-to-use features. The device is manufactured with reliable nonvolatile technology. The AT28C64 is accessed like a Static RAM for the read or write cycles without the need for external components. During a byte write, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. AT28C64 has additional features to ensure high quality and manufacturability. The device utilizes error correction internally for extended endurance and for improved data retention characteristics.
This article provides you with a basic overview of the AT28C64 64K Parallel EEPROM, including its pin descriptions, features and specifications, etc., to help you quickly understand what AT28C64 is.
