The Advanced Micro Devices AM27C256-205LI is a 256-kilobit UV Erasable Programmable Read-Only Memory (UVPROM) utilizing CMOS technology. This component features a memory organization of 32K words by 8 bits, providing a total density of 262,144 bits. It operates with an asynchronous, parallel interface and offers a maximum access time of 200 nanoseconds. The device is housed in a 32-terminal Ceramic Quad Flat Pack (CQFP) package, suitable for surface mounting. Operating within a temperature range of -40°C to +85°C, it requires a supply voltage of 5V ±10%. Applications for this type of memory component include industrial control systems and legacy equipment requiring non-volatile program storage. The output characteristics are 3-state, and the package is metal-sealed with a window for UV erasure.
