The Advanced Micro Devices AM27S31A-BUA is a 4Kb (512 x 8) bipolar, asynchronous OTP ROM. This device offers a maximum access time of 45ns, suitable for applications requiring rapid data retrieval. Operating from a nominal 5V supply (4.5V to 5.5V range), it features 3-state outputs and is housed in a 32-terminal CQCC package (R-CQCC-N32). The AM27S31 series is known for its robust performance in demanding environments, with an extended operating temperature range of -55°C to +125°C. This component finds application in industrial control systems, telecommunications infrastructure, and legacy computing platforms where reliable, non-volatile storage is critical. Its ceramic, metal-sealed cofired package construction ensures durability and thermal stability.
