DS1963L - 4k-BIT MONETARY iButton

The DS1963L Monetary iButton is a rugged read/write data carrier that acts as a localized database that can be easily accessed with minimal hardware.

The nonvolatile memory offers a simple solution to storing and retrieving information pertaining to the object to which the iButton is associated.

• 4096 bits of read/write nonvolatile memory.
• Overdrive mode boosts communication speed to 142 kbits per second.
• 256-bit scratchpad ensures integrity of data transfer.
• Memory partitioned into 256-bit pages for packetizing data.
• Data integrity assured with strict read/write protocols.
• Four 32-bit read-only non rolling-over page write cycle counters.
• 32 factory-preset tamper-detect bits to indicate physical intrusion.
• On-chip 16-bit CRC generator for safeguar.
