The Microchip Technology AT28C256-35FM-883 is a 262,144-bit (32K x 8) high-performance CMOS Electrically Erasable and Programmable Read-Only Memory. This parallel interface device offers a fast 350ns access time and supports asynchronous operation. Key features include hardware and software data protection mechanisms, ensuring data integrity with a minimum data retention of 10 years and an endurance of 10,000 write cycles. The AT28C256 series is designed for demanding applications, including aerospace, defense, and industrial control systems, where robust performance and reliability are paramount. It operates over a wide temperature range of -55°C to +125°C and utilizes a 28-lead Ceramic Flat Pack (CDFP) package, identified by JESD-30 code R-CDFP-F28, with a terminal pitch of 1.27mm. The device supports a 5V programming voltage and features a toggle bit for write verification.
