The Advanced Micro Devices 53S281L is a 256x8 bit OTP ROM from the 53S281 series. This bipolar memory component offers an asynchronous operating mode with a maximum access time of 50 nanoseconds. Featuring 3-state outputs and a parallel interface, it operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V. The device is housed in a 28-terminal Ceramic Quad Flat Pack (CQFP) package, specifically a JESD-30 S-CQCC-N28. Its operational temperature range spans from -55°C to +125°C. Applications for this memory type include industrial control systems and specialized embedded designs requiring non-volatile code storage. The package dimensions are 11.43mm square with a seated height of 2.54mm, and it utilizes a 1.27mm terminal pitch.
