The Maxim DS24B33+ is a compact 4 kB EEPROM memory device designed for secure and efficient data storage in embedded systems. Using a 1-Wire serial interface, it supports communication through a single data line and ground, simplifying PCB layout and reducing wiring complexity. Its low-pin-count TO-92 package offers flexibility for both industrial and embedded designs. Additionally, it delivers proven EEPROM reliability, compact packaging, and simplified 1-Wire connectivity, essential for smart devices and embedded controllers requiring secure, low-power data storage.

Fast Access and Reliable Data Retention

Engineered for high-speed performance, the DS24B33+ provides a 10 μs write access time and ensures long-term data retention even after power loss. The non-volatile memory structure safeguards stored information, making it suitable for configuration data, calibration parameters, and identification codes across a range of applications.

Compact and Efficient Design

With its 3-pin TO-92 package, this device is ideal for space-constrained designs where performance and simplicity are equally important. The compact format enables easy integration into sensors, controllers, security modules, and smart electronics, ensuring reliable operation with minimal PCB real estate.

Secure and Flexible 1-Wire Communication

The 1-Wire interface reduces component count and connection complexity, requiring only a single data line for communication and power. This simplifies system architecture while maintaining data integrity and communication reliability. The DS24B33+ also offers unique identification capabilities, supporting traceability and secure data access.
