The Microchip Technology AT28C256E-20SC is a 262,144-bit (32K x 8) Electrically Erasable Programmable Read-Only Memory. This CMOS EEPROM offers a fast 200ns access time, facilitating efficient data retrieval. Its parallel interface supports asynchronous operation with a 32K word organization, and includes features like data polling and a toggle bit for status monitoring. The device supports automatic write operations and has a write cycle time of 10ms. With an endurance of 100,000 write cycles, it is suitable for applications requiring frequent data updates. The AT28C256E-20SC operates from a 4.5V to 5.5V supply, with a nominal 5V requirement, and is available in a 28-lead PDSO package (JESD-30 Code R-PDSO-G28) for surface mounting. This component finds application in industrial control systems, automotive electronics, and data logging.
