DS1986 - 64-kbits Add-Only iButton

General Description

The DS1986 64-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.

Key Features

  • 65536 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground.
  • Overdrive mode boosts communication speed to 142 kbits per second www. DataSheet4U. com.
  • EPROM partitioned into two hundred and 56 256-bit 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 distur.
