These features make the DS2431P ideal for applications like asset tracking, sensor data storage, and system configuration in diverse electronic systems.

Package

The DS2431P is available in a 6-pin TSOC (Thin Small Outline Chip) package. This compact package is designed for surface mounting, providing a space-efficient solution for integrating the device into electronic circuits.

Pinout

The DS2431P is a 1-Wire EEPROM (Electrically Erasable Programmable Read-Only Memory) device with a total of 8 pins. The pin configuration and functions are as follows:
1. GND: Ground connection.
2. VDD: Power supply input (typically 2.8V to 5.25V).
3. DQ: Data line for 1-Wire communication that functions for both data transmission and power.
4. NC: No connect (not used).
5. NC: No connect (not used).
6. NC: No connect (not used).
7. NC: No connect (not used).
8. NC: No connect (not used).
The main function of the DS2431P is to provide a unique identification number and a small amount of writable EEPROM memory, making it suitable for applications in asset tracking, authentication, and product serialization. The device is accessed over a single wire protocol, allowing for easy integration into various electronic systems.
