Product Details
DS28EL15Q+T - DS28EL15 Low-Voltage 1-Wire SHA-256 Authenticator
DS28EL15Q+T from Analog Devices Inc./Maxim Integrated is a 1-Wire SHA-256 bidirectional secure authenticator with 512-bit user EEPROM for 1.8 V systems.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
DS28EL15 combines a hardware SHA-256 engine, protected secret and two 256-bit EEPROM pages for accessory and system authentication over a single-contact bus.
Key Advantages
Bidirectional SHA-256 authentication validates both host and peripheral while keeping the secret on-chip.
The single-contact 1-Wire interface and low-voltage supply suit compact battery-powered accessories.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
