Product details

Description

The DS28E02 combines 1024 bits of EEPROM with challenge-and-response authentication security implemented with the FIPS 180-3 Secure Hash Algorithm (SHA-1).

The 1024-bit EEPROM array is configured as four pages of 256 bits with a 64-bit scratchpad to perform write operations.

Features

1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits.
On-Chip 512-Bit SHA-1 Engine to Compute 160Bit 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.
User-Programmable Page Write Protection for Page 0, Page 3, or All Four Pages Together.
User-Programmable OTP EPROM Emulation Mode for Page 1 (“Write t.
