The Advanced Micro Devices 53S281AL is a 2048-bit (256 words x 8 bits) One-Time Programmable (OTP) Read-Only Memory (ROM) device. Featuring a bipolar technology, this component offers an asynchronous operating mode with a maximum access time of 40ns. The memory organization is 256 words by 8 bits, providing a total density of 2048 bits.
This device is housed in a 28-lead ceramic cofired chip carrier (CQCC28) package, specified by JESD-30 code S-CQCC-N28, with a 1.27mm terminal pitch. It operates within a supply voltage range of 4.5V to 5.5V, with a nominal voltage of 5V, and consumes a maximum supply current of 140mA. The operating temperature range spans from -55°C to +125°C. The 53S281AL is suitable for applications requiring high-reliability, non-volatile data storage in industrial and military environments. Its 3-state output characteristics facilitate bus-structured systems.
