製品の詳細
- Easily Add Traceability and Relevant Information to Any Individual System
- 1k-Bit EPROM with Page-Level Write Protection and Guaranteed Unique 64-Bit ROM ID Chip for Absolute Traceability
- 1024 Bits Electrically Programmable Read Only Memory (EPROM)
- Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code + 48-Bit Serial Number + 8-Bit CRC Tester)
- EPROM Partitioned into Four 256-Bit Pages for Randomly Accessing Packetized Data
- Each Memory Page Can Be Permanently Write- Protected to Prevent Tampering
- Device is an Add Only Memory Where Additional Data Can Be Programmed into EPROM Without Disturbing Existing Data
- Architecture Allows Software to Patch Data by Superseding an Old Page in Favor of a Newly Programmed Page
- 8-Bit Family Code Specifies DS2502 Communications Requirements to Reader
- Minimalist 1-Wire Interface Lowers Cost and Interface Complexity
- Reduces Control, Address, Data, Power, and Programming Signals to a Single Data Pin
- Directly Connects to a Single Port Pin of a Microprocessor and Communicates at up to 16.3kb Per Second
- Built-In Multidrop Controller Ensures Compatibility with Other 1-Wire Net Products o Presence Pulse Acknowledges When the Reader First Applies Voltage
- Low Cost TO-92, SFN, or 8-Pin SO, SOT-23 (3 Pin), TSOC and WLP Surface Mount Package
- Wide Voltage and Temperature Operating Ranges Provide Robust System Performance
- Reads Over Voltage Range of 2.8V to 6.0V at -40°C to +85°C
- Zero Standby Power Required
- Programs at 11.5V to 12.0V from -40°C to +50°C
