DS28E01-100

1Kb Protected 1-Wire EEPROM

with SHA-1 Engine

General Description

Features

The DS28E01-100 combines 1024 bits of EEPROM with

challenge-and-response authentication security imple-

mented with the ISO/IEC 10118-3 Secure Hash

Algorithm (SHA-1). The 1024-bit EEPROM array is con-

figured as four pages of 256 bits with a 64-bit scratch-

pad to perform write operations. All memory pages can

be write protected, and one page can be put in

EPROM-emulation mode, where bits can only be

changed from a 1 to a 0 state. Each DS28E01-100 has

its own guaranteed unique 64-bit ROM registration num-

ber that is factory lasered into the chip. The DS28E01-

♦ 1024 Bits of EEPROM Memory Partitioned Into

Four Pages of 256 Bits

♦ On-Chip 512-Bit 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

♦ User-Programmable Page Write Protection for

Page 0, Page 3, or All Four Pages Together

100 communicates over the single-contact 1-Wire bus.

The communication follows the standard 1-Wire protocol

with the registration number acting as the node address

in the case of a multidevice 1-Wire network.

♦ User-Programmable OTP EPROM Emulation Mode

for Page 1 (“Write to 0”)

♦ Communicates to Host with a Single Digital

Signal at 15.3kbps or 90.9kbps Using 1-Wire

Protocol

Applications

Printer Cartridge Configuration and Monitoring

Medical Sensor Authentication and Calibration

System Intellectual Property Protection

♦ Switchpoint Hysteresis and Filtering to Optimize

Performance in the Presence of Noise

♦ Reads and Writes Over 2.8V to 5.25V Voltage

Range from -40°C to +85°C

Typical Operating Circuit

♦ 6-Lead TSOC and TDFN or 2-Lead TO-92 and SFN
