1024-Bit, 1-Wire EEPROM

for Automotive Applications

DS243-A1

General Description

Features

The DS2431-A1 is an AEC-Q100 Grade 1 qualified ver-

sion of the DS2431. The logical behavior of both ver-

♦ 1024 Bits of EEPROM Memory Partitioned Into

Four Pages of 256 Bits

sions is identical. The DS2431-A1 is a 1024-bit, 1-Wire

♦ Individual Memory Pages Can Be Permanently

Write Protected or Put in EPROM-Emulation Mode

(“Write to 0”)

EEPROM chip organized as four memory pages of 256

bits each. Data is written to an 8-byte scratchpad, veri-

fied, 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-conduc-

tor 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 fac-

tory lasered into the chip. The registration number is

used to address the device in a multidrop 1-Wire net

environment.

♦ 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 or 125kbps Using 1-Wire

Protocol
