The DS2460S+ SHA-1 Coprocessor with EEPROM by Analog Devices / Maxim Integrated is a hardware implementation of the ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1). This device eliminates the need for software implementation of complex SHA computations, making it suitable for authenticating SHA devices and validating digitally signed service data.
Key features include a dedicated hardware-accelerated SHA engine for generating SHA-1 MACs and 112 Bytes of user EEPROM for storing end-equipment property data. The DS2460S+ communicates with a microcontroller via an I²C host interface, supporting both 100kHz and 400kHz communication speeds. It offers three address inputs for I²C address assignment and supports single-byte to 8-byte EEPROM write sequences.
This coprocessor has a wide operating voltage range of 2.7V to 5.5V and operates within a temperature range of -40°C to +85°C. It includes ±4kV IEC 1000-4-2 ESD protection on all pins. The device is available in an 8-pin SOIC package, suitable for surface mounting.
Applications for the DS2460S+ include license management, secure feature control, system authentication, clone prevention, door locks, and utility meters. It is also used for generating one-time-use encryption keys for short message encryption and decryption.
