MAX66240
ABRIDGED DATA SHEET
DeepCover Secure Authenticator with
ISO 15693, 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.
The DeepCover Secure Authenticator (MAX66240) is a
transponder IC that combines an ISO/IEC 15693 and ISO
18000-3 Mode 1-compatible RF front-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
MAX66240. Each device has its own guaranteed 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.
Features and Benefits
● Dedicated Hardware-Accelerated SHA Engine
● Strong Authentication with a High Bit Count User-
Programmable Secret and Input Challenge
● 4096 Bits of User EEPROM with User-Programmable
R/W Protection Options Including OTP/EPROM
Emulation Mode
● Unique Factory-Programmed 64-Bit Identification
Number
● ISO/IEC 15693: Up to 26kbps
● ±2kV HBM ESD Protection for All Pins
Applications
● Access Control
● Asset Tracking
Printer Cartridge Configuration and Monitoring
● Medical Sensor Authentication and Calibration
● System Intellectual Property Protection

Note 2: Limits are 100% production tested at TA = +25°C or TA = +85°C. Limits over the operating temperature range and relevant
supply voltage range are guaranteed by design and characterization. Typical values are at +25°C.
Note 3: For commands where the tCSHA interval occurs see the applicable communication examples sections. For RF commands,
the interval begins after the EOF of a valid request frame. The interval ends once the device’s self-timed SHA-256 compu-
tation cycle is complete.
Note 4: For commands where the tPROG interval occurs see the applicable communication examples sections. For RF commands,
the interval begins after the EOF of a valid request frame. The interval ends once the device’s self-timed EEPROM write
cycle is complete.
Note 5: Write-cycle endurance is tested in compliance with JESD47G.
Note 6: Not 100% production tested; guaranteed by reliability qualification.
Note 7: Data retention is tested in compliance with JESD47G.
Note 8: Guaranteed by 100% production test at elevated temperature for a shorter time; equivalence of this production test to the
data sheet limit at operating temperature range is established by reliability testing.
Note 9: EEPROM writes can become nonfunctional after the data-retention time is exceeded. Long-term storage at elevated tem-
peratures is not recommended.
Note 10: System requirement.
Note 11: Guaranteed by design and/or characterization only. Not production tested.
Note 12: Characterized in accordance with ISO/IEC 10373-7.
Note 13: Applies to Read/Write Scratchpad (writing), Write Memory, Compute and Read Page MAC, Set Protection, Authenticated
Write Memory RF Setup, Authenticated Write Memory RF Execute, Authenticated Set Protection RF Setup, and
Authenticated Set Protection RF Execute commands.
Note 14: Field strength between 350mA/m and 3A/m.
Note 15: Field strength between 350mA/m and 5A/m.
