MAX66242ETB+

Specialized ICS Overview

The MAX66242ETB+ is a DeepCover Secure Authenticator transponder IC from Analog Devices Inc./Maxim Integrated, housed in a 10-TDFN (3x4) surface-mount package. It integrates an ISO/IEC 15693 and ISO 18000-3 Mode 1 RF front-end, an I²C interface, a FIPS 180-based SHA-256 engine, and 4096 bits of user EEPROM. The device operates on a supply voltage range of 2.97V to 3.63V with active current consumption of 110µA. It features a factory-programmed unique 64-bit ROM ID for cryptographic operations and includes energy harvesting capabilities via the VOUT pin.

Specialized ICS Feature Summary

• Integrates SHA-256 engine for symmetric key-based bidirectional secure authentication
• Includes 4096 bits of user EEPROM with programmable protection modes (read, write, EPROM emulation, authentication)
• Supports ISO/IEC 15693 and ISO 18000-3 Mode 1 standards at 13.56 MHz carrier frequency
• Features configurable I²C master/slave port and PIO for sensor interfacing and energy harvesting

Specialized ICS Applications

• Access Control Systems
• Asset Tracking
• Medical Sensor Authentication and Calibration
• Printer Cartridge Configuration and Monitoring
• System Intellectual Property Protection

Specialized ICS Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to security-critical nature. Confirm package marking matches the 10-TDFN specification. Check for RoHS compliance documentation as indicated in official product listings. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to maintain reliability before soldering.

Specialized ICS Selection Notes

Select this component when both RFID authentication and local I²C peripheral management are required in a single chip. The 10-TDFN package suits space-constrained designs compared to larger SOIC options. Consider the energy harvesting VOUT capability if powering external low-current sensors is necessary. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.
