DS2432 - 1Kb Protected 1-Wire EEPROM

Key Features

  • 1128 Bits of 5V EEPROM Memory Partitioned Into Four Pages of 256 Bits, a 64-Bit Write-Only Secret, and Up to Five General-Purpose Read/Write Registers.
  • On-Chip 512-Bit ISO/IEC 10118-3 SHA-1 Engine to Compute 160-Bit Message Authentication Codes (MACs) and to Generate Secrets.
  • Write Access Requires Knowledge of the Secret and the Capability of Computing and Transmitting a 160-Bit MAC as Authorization.
  • Secret and Data Memory Can Be Write Protected (All or Page 0 Only) or Put i.
