The Intersil X2804CPI-20 is a 4K (512 x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) offering non-volatile data storage. This device is particularly well-suited for applications requiring reliable data retention during power loss and infrequent updates. The '20' likely refers to an access time, indicating 200ns, and 'CPI' likely refers to a specific package or temperature range.

Applications

• Embedded Systems: Used for storing configuration parameters, calibration data, and firmware in embedded systems.
• Industrial Control Systems: Integrated into PLCs and other industrial automation equipment to store operating parameters and program code.
• Instrumentation and Measurement Devices: Employed in instrumentation to store calibration curves and other critical data requiring long-term retention.
• Automotive Electronics: Suitable for storing configuration data in automotive control units and ECUs.
• Telecommunications Equipment: Used in routers, switches, and other network devices to store configuration settings.

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 fast access time (likely 200ns), enabling quick data retrieval.

Additional Details

The X2804CPI-20 typically operates from a single 5V power supply. It uses standard JEDEC pinouts for simplified design integration. The chip's endurance rating is a key parameter specifying the number of write/erase cycles it can reliably withstand. Access time is crucial for determining the overall performance of the memory system. The 'CPI' likely indicates a specific package type, temperature range or other industrial characteristics, which are not clearly documented without specific datasheets. This EEPROM is suitable for applications requiring moderate memory capacity, reliable data retention, and fast access times within industrial or extended temperature environments.
