DS28E07 - 1-Wire EEPROM

General Description

The DS28E07 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.

Key Features

  • Partitioning of Memory Provides Greater Flexibility in Programming User Data.
  • 1024 Bits of EEPROM Memory Organized as Four Pages of 256 Bits.
  • Individual Memory Pages Can Be Permanently Write Protected or Put in EPROM-Emulation Mode (Write to 0).
  • Advanced 1-Wire Protocol Minimizes Interface to Just Single IO Reducing Required Pin Count and Enhancing Reliability.
  • Unique Factory-Programmed, Unalterable 64-Bit Identification Number.
  • Switchpoint Hysteres.

1024-Bit, 1-Wire EEPROM Evaluation Kit Available Design Resources Support Click here to ask an associate for production status of specific part numbers. DS28E07 General Description The DS28E07 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 user 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. Each device has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip.
