DS2460
Description
The DS2460 SHA-1 Coprocessor with EEPROM is a hardware implementation of the ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1), eliminating the need to develop software to perform the plex SHA putation required for authenticating SHA devices and for performing the validation of digitally signed service data.
Key Features
- Dedicated Hardware-Accelerated SHA Engine for Generating SHA-1 MACs
- 112 Bytes User EEPROM for Storing End Equipment Property Data
- I²C Host Interface, Supports 100kHz and 400kHz munication Speeds
- Three Address Inputs for I²C Address Assignment
- Single-Byte to 8-Byte EEPROM Write Sequences
- 64-Bit Unique Registration Number
- EEPROM Endurance: 200k Cycles per 8-Byte Block at 25°C
- 10ms max EEPROM Write Cycle
- Wide Operating Range: 2.7V to 5.5V
- 40°C to +85°C
