DS2423 - 4kbit 1-Wire RAM

Key Features

  • 4096 bits of SRAM.
  • Four 32-bit, read-only counters.
  • Active-low external trigger inputs for two of the counters with on-chip debouncing compatible with reed and Wiegand switches.
  • Unique, factory-lasered and tested 64-bit registration number (8-bit family code + 48bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike.
  • Memory partitioned into 16 256-bit pages in for packetizing data.
  • 256-bit scratchpad with strict read/writ.
