Description

The DS1985 16-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.

Features

16384 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground.
EPROM partitioned into sixty-four 256-bit www. DataSheet4U. com pages for randomly accessing packetized data records.
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 supersedi.
