The Microchip Technology AT28HC256E-12LM is a 262,144-bit (32K x 8) CMOS Electrically Erasable Programmable Read-Only Memory organized as 32,768 words by 8 bits. This parallel interface device offers a fast 120ns access time and supports asynchronous operation. Key features include automatic write capabilities, data polling, and a toggle bit for status monitoring, simplifying write operations. Designed for robust performance, it operates over an extended temperature range of -55°C to +125°C and requires a 4.5V to 5.5V supply voltage. The AT28HC256 series is suitable for applications requiring non-volatile data storage in demanding environments, such as aerospace, defense, and industrial control systems, with a typical endurance of 100,000 write cycles. It is packaged in a 32-lead Ceramic Quad Flat Pack (CQFP) with a metal-sealed cofired ceramic body.
