The Intersil X2804AP-25 is a 4K (512 x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) device designed for reliable non-volatile data storage. This memory chip is ideal for applications where data retention is crucial even during power loss and infrequent data updates are needed. The '-25' likely refers to an access time of 250ns.

Applications

• Embedded Systems: Storing firmware, configuration parameters, and calibration data in embedded systems.
• Industrial Control Systems: Used in PLCs and other industrial equipment to store operating parameters and program code.
• Instrumentation and Measurement Devices: Storing calibration curves and other critical data that needs to be retained over extended periods.
• Automotive Electronics: Suitable for storing configuration data in automotive ECUs and other control 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.
• Non-Volatile Storage: Retains data even when power is removed.
• Fast Access Time: Offers a relatively fast access time (likely 250ns), enabling quick data retrieval.
• Electrically Erasable and Programmable: Allows data to be easily erased and reprogrammed electrically.

Additional Details

The X2804AP-25 typically operates from a single 5V power supply and utilizes standard JEDEC pinouts. The chip's endurance rating is an important specification that indicates the number of write/erase cycles the device can reliably handle. The access time is a critical parameter that affects the overall performance of the memory system. This EEPROM is suitable for applications requiring moderate memory capacity, reliable data retention, and fast access times.
