ADIDS2431P+T&R

Overview

The DS2431P+T&R is a 1024-bit, 1-Wire EEPROM organized into four 256-bit pages. It is designed for applications where minimal interconnect is required, as both power and data are delivered over a single signal line plus a ground return.

Why Choose This Part

The 1-Wire interface reduces the interconnect to a single port pin, making it ideal for space-constrained designs. It features robust IEC 1000-4-2 Level 4 ESD protection and allows individual pages to be permanently write-protected for data security.

Applications

Getting Started

To interface with the DS2431, implement a 1-Wire master on a microcontroller GPIO or use a dedicated bridge IC like the DS2482-100. Engineers should follow the 1-Wire protocol timing requirements for the 'Write Scratchpad' and 'Copy Scratchpad' sequences to ensure reliable data retention.
