Maxim Integrated 1024-BIT 1-Wire EEPROM Part #DS2431X+U | IC | DEX

Maxim Integrated 1024-BIT 1-Wire EEPROM Part #DS2431X+U

The DS2431 is a 1024-bit, 1-Wire EEPROM chip organized as four memory pages of 256 bits each. Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, the four memory pages can individually be written protected or put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. The DS2431 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number that is factory lasered into the chip. The registration number is used to address the device in a multidrop, 1-Wire net environment.

Applications:

• Accessory/PCB Identification
• Medical Sensor Calibration Data Storage
• Analog Sensor Calibration Including IEEE P1451.4 Smart Sensors
• Ink and Toner Print Cartridge Identification
• After-Market Management of Consumables

Benefits and Features:

• Easily Add Traceability and Relevant Information to Any Individual System
• 1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits
• Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode (Write to 0)
• Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
• Minimalist 1-Wire Interface Lowers Cost and Interface Complexity
• IEC 1000-4-2 Level 4 ESD Protection (8kV Contact, 15kV Air, typ)
• Reads and Writes Over a Wide Voltage Range from 2.8V to 5.25V from -40C to +85C
• Communicates to Host with a Single Digital Signal at 15.4kbps or 125kbps
