It is qualified to AEC-Q100. ## 2 µs access time — what it means for the bus The 2 µs access time is the interval from the end of the read command to valid data on the 1-Wire bus. ## Temperature range and environment Rated for -40°C to 125°C ambient, the DS2431P-A1+T covers automotive under-hood and cabin environments. ## Package and rework considerations Supplied in a 6-pin TSOC package (J-lead, SMD). ## Lifecycle and sourcing The DS2431P-A1+T is listed as Active, with no end-of-life notification. It is RoHS3 compliant.","metaTitle":"DS2431P-A1+T 1Kbit EEPROM, 1-Wire, 2 µs, AEC-Q100","metaDescription":"Maxim Integrated DS2431P-A1+T 1Kbit EEPROM, 1-Wire interface, 2 µs access time, -40°C to 125°C, AEC-Q100, 6-TSOC package.

The 1-Wire bus uses a pull-up resistor to the supply rail; the device's input thresholds are referenced to the supply voltage, so it works with any supply from 2.8V to 5.25V typically."},{"question":"What is the closest pin-compatible alternative to DS2431P-A1+T?","answer":"The standard DS2431 (non-automotive grade) is pin-compatible but lacks AEC-Q100 qualification.
