DS2431P+

The DS2431P+ is a 1024bit, 1-Wire EEPROM in 6 pin TSOC package. This EEPROM chip is organized as four memory pages of 256 bits each. Data is written to an 8byte scratchpad, verified and then copied to EEPROM memory. The four memory pages can individually be write protected or put in EPROM emulation mode where bits can only be changed from 1 to 0 state. The DS2431 communicates over single conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64bit ROM registration number that is factory lasered into chip. The registration number is used to address device in a multidrop, 1-wire net environment.

• Easily add traceability and relevant information to any individual system
• Switchpoint hysteresis and filtering to optimize performance in presence of noise
• 1-wire interface lowers cost and interface complexity
• IEC 1000-4-2 level 4 ESD protection (±8KV contact, ±15KV air)
• Reads and writes over wide voltage range from 2.8V to 5.25V from -40°C to 85°C
• Communicates to host with single digital signal at 15.4Kbps or 125Kbps
• Operating temperature range from -40°C to 85°C
• Accessory/PC Board Identification; After-Market Management of Consumables; Analog Sensor Calibration Including IEEEP 1451.4 Smart Sensors;
• Ink and Toner Print Cartridge Identification; Medical Sensor Calibration Data Storage
