DS2432规格书详情
DESCRIPTION
The DS2432 combines 1024 bits of EEPROM, a 64-bit secret, an 8-byte register/control page with up to five user read/write bytes, a 512-bit SHA-1 engine, and a fully-featured 1-Wire interface in a single chip. Each DS2432 has its own 64-bit ROM registration number that is factory lasered into the chip to provide a guaranteed unique identity for absolute traceability. Data is transferred serially via the 1-Wire protocol, which requires only a single data lead and a ground return.
FEATURES
1128 Bits of 5V EEPROM Memory Partitioned Into Four Pages of 256 Bits, a 64-Bit Write-Only Secret, and Up to Five General-Purpose Read/Write Registers
On-Chip 512-Bit ISO/IEC 10118-3 SHA-1 Engine to Compute 160-Bit Message Authentication Codes (MACs) and to Generate Secrets
Write Access Requires Knowledge of the Secret and the Capability of Computing and Transmitting a 160-Bit MAC as Authorization
Secret and Data Memory Can Be Write Protected (All or Page 0 Only) or Put in EPROM-Emulation Mode (“Write to 0”, Page 1)
Unique, Factory-Lasered and Tested 64-Bit Registration Number Assures Absolute Traceability Because No Two Parts Are Alike
Built-In Multidrop Controller Ensures Compatibility with Other 1-Wire® Net Products
Reduces Control, Address, Data, and Power to a Single Data Pin
Directly Connects to a Single Port Pin of a Microprocessor and Communicates at Up to 15.3kbps
Overdrive Mode Boosts Communication Speed to 125kbps
Low-Cost 6-Lead TSOC Surface-Mount Package or Solder-Bumped UCSP™ Package
Reads and Writes Over a Wide Voltage Range of 2.8V to 5.25V from -40°C to +85°C
