MAX66242 - DeepCover Secure Authenticator with ISO 15693, I²C, SHA-256, and 4Kb User EEPROM - 1-Wire器件 - Industry's First SHA-256 Symmetric Key-Based Authenticator with I²C Master Port - 美信半导体

产品概述

DeepCover? embedded security solutions cloak sensitivedata under multiple layers of advanced physical securityto provide the most secure key storage possible.

Our Secure Drug Delivery video shows how Maxim security products can be used to authenticate remote drug delivery.

The DeepCover Secure Authenticator (MAX66242) is atransponder IC that combines an ISO/IEC 15693 and ISO18000-3 Mode 1-compatible RF front-end, an I2C front-end,a FIPS 180-based SHA-256 engine and 4096 bitsof user EEPROM in a single chip. A bidirectional securitymodel enforces two-way authentication between a hostsystem and the MAX66242. Each device has its own guaranteedunique 64-bit ROM ID that is factory programmedinto the chip. This ROM ID is used as a fundamental inputparameter for cryptographic operations and serves as anelectronic serial number within the application.

In addition to the RF interface, the MAX66242 also has anI2C interface, which can operate as a slave or master port.When acting as a master, the MAX66242 can gather informationfrom a connected sensor or peripheral device andrelay its data via the RF port. When acting as a slave, thedevice can serve as an intermediary between a connectedhost and an RF reader. The MAX66242 can harvest energyfrom an active RF field. The configurable supply outputcan deliver up to 5mA given adequate field strength.
