DS2431P Description

Short technical summary and product information.

The DS2431P is a 1024-bit serial EEPROM utilizing the 1-Wire protocol, developed by Analog Devices (formerly Maxim Integrated). This memory chip is partitioned into four pages, each containing 256 bits, allowing for flexible data storage and management. A key feature is the ability to individually write-protect each memory page or enable EPROM-emulation mode, where data bits can only be changed from a 1 to a 0 state.

 

The DS2431P communicates using a minimalist 1-Wire interface, which simplifies system design and reduces costs. It supports two communication speeds: 15.4kbps and 125kbps. The device operates over a wide voltage range of 2.8V to 5.25V and maintains functionality across a broad temperature spectrum from -40°C to +85°C. It also features IEC 1000-4-2 Level 4 ESD protection.

 

This EEPROM is available in various package types including TO-92, TSOC, SFN (6mm x 6mm and 3.5mm x 6.5mm), TDFN-EP, and UCSPR. Mounting options include both Through Hole and Surface Mount. The DS2431P is suitable for applications requiring traceability and relevant information storage, such as accessory identification, medical sensor calibration, ink cartridge identification, and after-market management of consumables.
