The Advanced Micro Devices AM27C256-55LI is a 256 kilobit UV erasable programmable read-only memory (UVPROM). This CMOS device features a memory organization of 32K words by 8 bits, providing a total density of 262,144 bits. It operates asynchronously with a maximum access time of 55ns. The AM27C256 series utilizes a 5V supply voltage range (4.5V to 5.5V) and offers 3-state outputs. Packaged in a 32-terminal ceramic quad flat chip carrier (CQCC32) with a window for UV erasure, this component is suitable for surface mounting. Typical applications include industrial control, telecommunications, and legacy system designs requiring non-volatile code storage. The device operates over a temperature range of -40°C to +85°C.
