DS2431-A1 Datasheet (Analog Devices)

DS2431-A1, 1-Wire EEPROM

The DS2431-A1 is an AEC-Q100 Grade 1 qualified version of the DS2431.

The logical behavior of both versions is identical.

The DS2431-A1 is a 1024-bit, 1-Wire® EEPROM chip organized as four memory pages of 256 bits each.

Data is written to an 8-byte scratchpad, verified, and then copied to the EEPROM

DS2431-A1 Features

* 1024 Bits of EEPROM Memory Partitioned Into Four Pages of 256 Bits

* Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode (“Write to 0”)

* Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise

* IEC 1000-4-2 Level
