The Intersil X2804AD-35 is a 4K (512 x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device. This non-volatile memory chip offers a reliable solution for storing and retrieving data in various electronic systems. It is particularly useful in applications requiring infrequent data updates or where data retention is crucial even when power is removed. The '35' likely refers to an access time, suggesting 350ns.

Applications

• Data storage for embedded systems: Used in systems where configuration parameters or calibration data needs to be stored persistently.
• Industrial control systems: Employed in programmable logic controllers (PLCs) and other industrial equipment to store program code and operating parameters.
• Instrumentation and measurement devices: Used for storing calibration curves and other critical data that must be retained over long periods.
• Automotive electronics: Suitable for storing configuration data in engine control units (ECUs) and other automotive modules.
• Telecommunications equipment: Used to store configuration settings in routers, switches, and other network devices.

Features

• 4K (512 x 8) EEPROM: Provides 4096 bits of non-volatile memory organized as 512 bytes of 8 bits each.
