MAX66242ESA+ Description

Short technical summary and product information.

The Analog Devices / Maxim Integrated MAX66242ESA+ is a DeepCover Secure Authenticator IC designed for robust security applications. This transponder IC integrates an ISO/IEC 15693 and ISO 18000-3 Mode 1-compatible RF front-end, an I2C interface, a FIPS 180-based SHA-256 engine, and 4096 bits of user EEPROM.

It provides a complete counterfeit, cloning, and IP protection engine with a symmetric key-based bidirectional secure authentication model. The device includes a unique 64-bit ROM ID for cryptographic operations and serves as an electronic serial number. The I2C interface can operate as a master or slave, enabling it to gather sensor data or act as an intermediary.

Key features include batteryless RF communication, user-programmable memory with R/W protection options, and energy harvesting capabilities from an active RF field, delivering up to 5mA. The MAX66242ESA+ is suitable for applications such as access control, asset tracking, and medical sensor authentication.

Packaged in an 8-SOIC surface-mount case, this IC operates within a temperature range of -40°C to +85°C and offers ±4kV HBM ESD protection on PIO pins.
