The Advanced Micro Devices AM27C256 is a 32K x 8 UV Erasable Programmable Read-Only Memory (UVPROM) device offering a 262,144 bit density. This CMOS component features a maximum access time of 300ns and operates asynchronously. Designed for high-reliability applications, it supports a supply voltage range of 4.75V to 5.25V with a nominal 5V requirement. The output characteristics are 3-state, and the device is packaged in a 32-terminal Ceramic Quad Flat Pack (CQFP) with a window for erasure. Operating temperature ranges from -40°C to +85°C. This memory component finds utility in industrial control systems, telecommunications infrastructure, and legacy system upgrades where reliable non-volatile data storage is critical.
