The Microchip Technology AT27256-20DM1 is a 32K x 8 CMOS UV Electrically Programmable Read-Only Memory (UV EPROM). This device offers a 200ns access time and operates across a wide temperature range of -55°C to +125°C. It features an asynchronous operating mode and a parallel interface. The memory organization is 32K words by 8 bits, providing a total density of 262,144 bits. The component utilizes a 28-pin Ceramic Dual In-line Package (CDIP) with a window for UV erasure, conforming to the R-GDIP-T28 standard. Its through-hole terminal form factor with a 2.54mm pitch is suitable for traditional PCB assembly. Applications for this type of non-volatile memory include industrial control systems, legacy equipment, and embedded systems requiring reliable, erasable program storage. The AT27256 series is designed for robust performance in demanding environments.
