Product details

Description

The DS1982 1-kbit Add-Only iButton is a rugged read/write data carrier that identifies and stores relevant information about the product or person to which it is attached.

This information can be accessed with minimal hardware, for example, a single port pin of a microcontroller.

Features

1024 bits Electrically Programmable ReadOnly Memory (EPROM) communicates with the economy of one signal plus ground EPROM partitioned into four 256-bit pages www. DataSheet4U. com for randomly accessing packetized data Each memory page can be permanently write-protected to prevent tampering Device is an “add only” memory where additional data can be programmed into EPROM without disturbing existing data Architecture allows software to patch data by superseding an old page in favor of a newly progr.
