Product details

Automotive-grade 1Kbit EEPROM with 1-Wire interface

The Maxim Integrated DS2431P-A1+T is a 1Kbit serial EEPROM with a 1-Wire interface, organized as 256 x 4 bits. 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.

Frequently asked questions

Is DS2431P-A1+T RoHS compliant?

Yes, DS2431P-A1+T is RoHS3 compliant per the manufacturer's status.

Can DS2431P-A1+T be used with 3.3V logic?

Yes, the 1-Wire interface operates over a wide voltage range and is compatible with 3.3V logic. 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.

What is the closest pin-compatible alternative to DS2431P-A1+T?

The standard DS2431 (non-automotive grade) is pin-compatible but lacks AEC-Q100 qualification. For automotive applications, the DS2431P-A1+T is the correct choice; there is no direct automotive-grade second source from another manufacturer in the same package.
