1024-Bit, 1-Wire EEPROM

DS2431

General Description

Features

♦ 1024 Bits of EEPROM Memory Partitioned Into

The DS2431 is a 1024-bit, 1-Wire EEPROM chip orga-

nized 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 communi-

cates over the single-conductor 1-Wire bus. The commu-

nication follows the standard 1-Wire protocol. Each

device has its own unalterable and unique 64-bit ROM

registration number that is factory lasered into the chip.

The registration number is used to address the device in

a multidrop, 1-Wire net environment.

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 ( 8ꢀk

Contact, 15ꢀk ꢁir, ꢂypical)

♦ Reads and Writes Over a Wide koltage Range
