The Advanced Micro Devices AM27256 is a 262144-bit (32K x 8) One-Time Programmable (OTP) Read-Only Memory (ROM) utilizing NMOS technology. This component offers a maximum access time of 300ns, making it suitable for applications requiring rapid data retrieval. The memory organization is 32K words by 8 bits, providing a standard parallel interface. The AM27256 operates asynchronously within a temperature range of 0°C to 70°C and is powered by a nominal 5V supply (4.75V to 5.25V). It features 3-state outputs for flexible bus interfacing. Encased in a 32-terminal Ceramic Quad Flat Pack (CQFP) with a metal-sealed cofired package body, this component is designed for surface mounting. Its robust construction and performance characteristics align with requirements in industrial control, consumer electronics, and legacy system designs.
