The DS2431X is a 1-Kb EEPROM chip organized as one page of 32 bytes, with an additional 64-bit registration number that acts as its unique identity for traceability and control on a 1-Wire network. Data is transferred serially through the 1-Wire protocol, which requires only a single data lead and a ground return for communication.
Applications:
- Battery pack identification
- Medical sensor calibration data storage
- Electronic cash handles
- Access control
Features:
- 1024 bits of EEPROM memory organized as one page of 32 bytes
- Page write cycle time: 5ms (typical)
- Write cycle endurance of 500,000 cycles (minimum)
- Data retention of 10 years (minimum)
- Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48-bit serial number + 8-bit CRC tester) assures absolute traceability
- Built-in multidrop controller for single-point control of multiple devices
- Communicates to host with a single digital signal at 14.2kbps using 1-Wire protocol
- Operating temperature range of -40°C to +85°C
Benefits:
- Offers flexible and reliable nonvolatile memory for various applications.
- Provides a cost-effective solution for storing configuration and calibration data.
- Simplifies system design with its single-wire communication interface.
- Ensures data integrity with its built-in error detection and correction features.
The DS2431X's EEPROM memory can be used to store configuration, calibration, or other critical information. The unique 64-bit registration number allows for individual identification and tracking of devices on a 1-Wire network. The device derives its power from the 1-Wire communication line, eliminating the need for an external power supply.
