ABRIDGED DATA SHEET

MAX66242

DeepCover Secure Authenticator with

ISO 15693, I C, SHA-256, and 4Kb User EEPROM

General Description

DeepCover embedded security solutions cloak sensitive

data under multiple layers of advanced physical security

to provide the most secure key storage possible.

Beneﬁts and Features

● Complete Counterfeit/Cloning/IP Protection Engine

• SHA-256 Engine Runs a Symmetric Key-Based

Bidirectional Secure Authentication

• Strong Authentication Achieved with a High Bit Count,

User-Programmable Secret, and Input Challenge

• Batteryless RF Communication

The DeepCover Secure Authenticator (MAX66242) is a

transponder IC that combines an ISO/IEC 15693 and ISO

18000-3 Mode 1-compatible RF front-end, an I C front-

• 4096 Bits of User EEPROM with User-Programmable

Memory

• Memory R/W Protection Options Including OTP/

EPROM Emulation Mode

• Unique Factory-Programmed 64-Bit Identiﬁcation

Number

end, a FIPS 180-based SHA-256 engine and 4096 bits

of user EEPROM in a single chip. A bidirectional security

model enforces two-way authentication between a host

system and the MAX66242. Each device has its own guar-

anteed unique 64-bit ROM ID that is factory programmed

into the chip. This ROM ID is used as a fundamental input

parameter for cryptographic operations and serves as an

electronic serial number within the application.

• Integrated 32-Byte SRAM Buﬀer Enables Faster

HF-to-I C Transactions

● Flexible Connection and Communication Capabilities

Support a Wide Range of Applications

In addition to the RF interface, the MAX66242 also has an

I C interface, which can operate as a slave or master port.

• Programmable I/O (PIO) Can Be Conﬁgured as a

Wake-Up or Monitoring/Control Signal

When acting as a master, the MAX66242 can gather infor-

mation from a connected sensor or peripheral device and

relay its data via the RF port. When acting as a slave, the

device can serve as an intermediary between a connected

host and an RF reader. The MAX66242 can harvest ener-

gy from an active RF field. The configurable supply output

can deliver up to 5mA given adequate field strength.

• HF Standards ISO/IEC 15693 and 18000-3 MODE1

Compatible (13.56 MHz ±7kHz Carrier Frequency)

• I C Interface—Master/Slave Port Eliminates Host

Microcontroller for Sensor-Tag Applications

• Energy Harvesting V

Applications

● Access Control

• Optional 3.3V Supply Voltage Fits Line and

Battery-Powered Applications

• -40°C to +85°C Operating Temperature Range

● Asset Tracking

● Printer Cartridge Conﬁguration and Monitoring

● Medical Sensor Authentication and Calibration

● System Intellectual Property Protection

● Enables Robust Design

• ±4kV HBM ESD Protection on PIO, ±2kV on All

Other Pins
