The Advanced Micro Devices AM27256-1LE is a 32768 x 8 bit (32K x 8) NMOS Electrically Programmable Read-Only Memory (EPROM) designed for high-performance applications. Featuring an asynchronous operating mode, this device offers a maximum access time of 170ns, ensuring rapid data retrieval. The memory organization provides 32K words, each 8 bits wide, with a total memory density of 262144 bits.
This component utilizes a robust Ceramic Quad Flat Pack (CQFP) package, specifically a CQCC32 (R-CQCC-N32), suitable for surface mounting. The NMOS technology contributes to its reliable operation across a wide temperature range, from -55°C to +125°C. The AM27256-1LE is commonly found in industrial control systems, telecommunications infrastructure, and embedded computing platforms where stable, non-volatile program storage is critical. Its 3-state output characteristics facilitate bus-oriented system designs. The device operates from a nominal supply voltage of 5V, with a maximum allowable tolerance of 4.75V to 5.25V.
