MAX66242ISA-A+

Specialized ICS Overview

The MAX66242ISA-A+ is a DeepCover Secure Authenticator transponder IC from Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC package. It integrates an ISO/IEC 15693 and ISO 18000-3 Mode 1 RF front-end with an I²C interface, a FIPS 180-based SHA-256 engine, and 4096 bits of user EEPROM. The device features a factory-programmed unique 64-bit ROM ID for cryptographic operations and bidirectional security authentication. Operating on a 3.3V supply (2.97V to 3.63V), it draws 110µA active current and supports energy harvesting via the VOUT pin. The component functions as both an RF transponder and an I²C master/slave port, enabling secure data storage and sensor interfacing within a -20°C to +85°C temperature range.

Specialized ICS Procurement Notes

Verify the specific suffix 'ISA-A+' against official manufacturer documentation to confirm exact qualification grade and packaging configuration. Ensure compatibility with the required operating voltage range of 2.97V to 3.63V and thermal constraints for the 8-SOIC package during integration.

Specialized ICS Selection Notes

Select this component when high-security anti-counterfeiting and IP protection are required for passive or semi-passive tags. The integrated I²C master capability allows direct connection to external sensors without a host microcontroller, simplifying system design for medical and industrial asset tracking applications.

Specialized ICS Part Context

This part belongs to the Maxim Integrated DeepCover® family of embedded security solutions. These devices are designed to protect sensitive data through multiple layers of physical security and cryptographic engines, providing robust counterfeit and cloning protection for IoT and industrial applications.

Specialized ICS Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may lack the specific SHA-256 hardware engine or ISO 15693 compliance required for secure authentication protocols.
