Description

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
