See all from this product rangeProduct Overview
DS2431P-A1+T is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256bits 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 write protected or put in EPROM-emulation mode, where bits can only be changed from a 1 to a 0 state. It 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 include automotive sensor identification and calibration data storage, automotive cable assembly identification, and accessory/PCB identification.
- 1024bits of EEPROM memory partitioned into four pages of 256bits
- Switchpoint hysteresis and filtering to optimize performance in the presence of noise
- IEC 1000-4-2 level 4 ESD protection (+8KV contact, +15KV air, typ)
- Reads and writes over a 4.5V to 5.25V voltage range from -40°C to +125°C
- Communicates to host with a single digital signal at 15.4kbps using 1-wire protocol
- Meets AEC-Q100 grade 1 qualification requirements
- Recovery time is 5µs min at RPUP=2.2Kohm
- EEPROM programming current is 0.8mA maximum
- 6 TSOC package
- Temperature range from -40°C to +125°C
