Additional Details:

The SMJ27C512-25JM operates with a single 5V power supply and features TTL compatible inputs and outputs, making it easy to interface with a wide range of microprocessors and microcontrollers. The device is packaged in a JEDEC standard 28-pin package, simplifying board layout and assembly. Erasure is accomplished by exposing the chip to ultraviolet light through the quartz window. The device is typically used to store boot code, configuration data, or other critical information that must be retained when power is removed. The 250ns access time ensures rapid data retrieval, which is crucial in performance-sensitive applications. It is specifically designed and manufactured by Austin Semiconductor with stringent quality control, making it ideal for use in high-reliability industries such as aerospace and defense.
