It combines an energy harvesting controller with a secure serial EEPROM.The DS28E36Q+U is ideal for applications in which energy must be derived from a variety of sources, and for the secured storage and handling of authentication data in batteryless or battery-backed systems.

Application Field

The DS28E36Q+U is designed for a wide variety of applications, including:

• Automotive, industrial and remote controls
• Smart cards
• Home security sensors
• Smart meters
• Medical and healthcare sensors
• Smart lighting, irrigation and home appliances
• Access control systems

The DS28E36Q+U is ideal for use in networks requiring secure authentication of various devices, including Zigbee, Bluetooth Low Energy (BLE) and other proprietary wireless protocols.

Working Principle

The DS28E36Q+U utilizes an Energy Harvesting Controller (EHC) to collect energy from any external source and directly power the IC. When sufficiently energized, the EHC allows secure communication and data storage to take place.The EHC is also used to write data to the internal secure EEPROM, which allows for secure storage and handling of authentication data in batteryless or battery-backed systems.

The DS28E36Q+U also provides enhanced security for applications through the use of its on-board cryptographic engine. This engine is capable of supporting a variety of secure protocols, such as SHA-256, ECDSA and other algorithms. Furthermore, the device provides protection for data stored in the EEPROM through the use of enhanced production-test and anti-tamper functions. This ensures that data is only readable by authorized personnel.

In addition to its cryptographic engine, the DS28E36Q+U also offers an integrated energy management system and an integrated temperature sensor. This energy management system allows the device to optimize energy usage in order to extend system lifetime, while the temperature sensor helps to ensure that the temperature of the system stays within specified limits.

The DS28E36Q+U is a versatile memory solution that can be used in a variety of challenging applications. Its combination of energy harvesting, secure authentication, enhanced production-test and anti-tamper functions make it a comprehensive, secure and reliable solution for any application that requires the secured storage and handling of authentication data.
