Microchip Technology AT28C256-30FM-883 is a 262144-bit (32K x 8) CMOS Electrically Erasable Programmable Read-Only Memory. This non-volatile memory device offers a 300ns access time, facilitating efficient data retrieval in demanding applications. The AT28C256 series features hardware and software data protection mechanisms, ensuring data integrity with a minimum data retention of 10 years. Its endurance rating stands at 10,000 write/erase cycles. Designed for parallel interface, it operates asynchronously and supports data polling and a toggle bit for status monitoring. The component is housed in a 28-lead ceramic flatpack (CDFP28) package, suitable for surface mounting, with a terminal pitch of 1.27mm. This device operates within a temperature range of -55°C to 125°C and is rated for military-grade screening (883B). Applications include aerospace, defense, and industrial systems requiring reliable data storage under harsh environmental conditions.
