Advanced Micro Devices AM27S33A-B2A is a 4Kb (1K x 4) bipolar OTP ROM with a maximum access time of 55ns. This asynchronous memory component features a 3-state output for bus compatibility and operates from a nominal 5V supply voltage (4.75V to 5.25V). The device is housed in a 20-terminal Ceramic Chip Carrier (CQCC20) package with a terminal pitch of 1.27mm, suitable for surface mounting. It is rated for an extended industrial temperature range of -55°C to 125°C and adheres to screening levels such as 38535Q/M, 38534H, and 883B. Applications include industrial control systems and defense electronics where robust, high-temperature operation is critical.
