DS2431-A1 - 1-Wire EEPROM

General Description

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.

Key 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 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.

DS2431-A1 Rev 1; 3/08 1024-Bit, 1-Wire EEPROM for Automotive Applications General Description 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 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. The DS2431-A1 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol.
