Additional Details

The AM2764-25/BXA operates from a single 5V power supply. The device is programmed by applying a higher voltage to specific pins using an EPROM programmer. It is erasable by exposing the die to ultraviolet (UV) light through a quartz window located on the top of the package. This EPROM is frequently found in legacy embedded systems where it stores boot code, configuration data, or other critical information. The 250ns access time makes it suitable for applications with moderate speed requirements. Proper handling is essential to avoid electrostatic discharge, which could damage the device.
