The X5043 is a 4K bit CMOS Serial EEPROM with Block Lock™ Protection manufactured by Xicor Inc. (later acquired by Intersil, now Renesas). It is a non-volatile memory device that provides a simple and cost-effective solution for storing configuration data and other information that needs to be retained when power is removed. It uses a serial interface for communication with a microcontroller or other digital system.

Applications

• Consumer Electronics: Storing user preferences and settings in TVs, radios, and other appliances.
• Industrial Equipment: Storing calibration data, configuration parameters, and event logs.
• Medical Devices: Storing patient data, device settings, and diagnostic information.
• Automotive Electronics: Storing vehicle identification numbers, engine control parameters, and diagnostic codes.
• Telecommunications: Storing network configuration data, subscriber information, and billing records.

Features

• 4K Bits (512 x 8) of EEPROM: Provides a small but sufficient amount of non-volatile storage.
• Serial Interface: Uses a simple serial protocol for communication (typically SPI or Microwire).
• Low Voltage Operation: Operates at low voltages, making it suitable for battery-powered applications.
• Low Power Consumption: Minimizes energy usage in portable devices.
• Block Lock™ Protection: Prevents accidental overwriting of critical data.
• Self-Timed Write Cycle: Simplifies write operations and reduces software overhead.
• High Reliability: Provides long-term data retention and endurance.
