Additional Details
The AM27128A-20/BXA requires a single 5V power supply for operation. The device is programmed by applying a higher voltage to specific pins using an EPROM programmer. The contents of the EPROM can be erased by exposing the die to ultraviolet (UV) light through a quartz window on the package. The AM27128A is often found in older embedded systems, industrial control equipment, and other applications where non-volatile memory is required. The 200ns access time makes it suitable for systems with moderate speed requirements.
