Микросхема DS2433

DS2433

• 4096 Bits Electrically Erasable Programmable Read-Only Memory (EEPROM)
• Unique, Factory-Lasered and Tested 64-Bit Registration Number (8-Bit Family Code + 48-Bit Serial Number + 8-Bit CRC Tester) Assures Absolute Identity Because No Two Parts Are Alike
• Built-In Multidrop Controller Ensures Compatibility with Other MicroLAN Products
• Memory Partitioned Into Sixteen 256-Bit Pages for Packetizing Data
• 256-Bit Scratchpad with Strict Read/Write Protocols Ensures Integrity of Data Transfer
• 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 16.3kbps
• Overdrive Mode Boosts Communication Speed to 142kbps
• 8-Bit Family Code Specifies DS2433 Communication Requirements to Reader
• Presence Detector Acknowledges When Reader First Applies Voltage
• Low-Cost PR-35, SFN, Flip Chip, or 8-Pin SO Surface-Mount Packages
• Reads and Writes Over a Wide Voltage Range of 2.8V to 6.0V from -40°C to +85°C
