产品概述

The DS28E25+ is a DeepCover secure authenticator with 1-wire SHA-256 and 4Kb user EEPROM in 2 pin TO-92 package. The DeepCover embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide most secure key storage possible. The DeepCover secure authenticator (DS28E25) combines crypto-strong, bidirectional, secure challenge and response authentication functionality with an implementation based on the FIPS 180-3-specified secure hash algorithm (SHA-256). A 4Kb user-programmable EEPROM array provides non-volatile storage of application data and additional protected memory holds a read protected secret for SHA-256 operations and settings for user memory control. It has its own unique 64bit ROM identification number (ROM ID) that is factory programmed into the chip. It is used in authentication of network-attached appliances, printer cartridge ID/authentication, reference design license management and system intellectual property protection.
  • Supply voltage range is 2.97V to 3.63V
  • Operating temperature range from -40°C to 85°C
  • Symmetric key based bidirectional secure authentication model based on SHA-256
  • Dedicated hardware accelerated SHA engine for generating SHA-256 MACs
  • Strong authentication with high bit count, user programmable secret and input challenge
  • 4096bits of user EEPROM partitioned into 16Pages of 256bits
  • Unique, factory-programmed 64bit identification number
  • Single contact 1-wire interface communicates with host at up to 76.9Kbps
  • ±8KV human body model ESD protection (typ)
