1024-Bit, 1-Wire EEPROM

DS28E07

General Description

Beneﬁts and Features

● Partitioning of Memory Provides Greater Flexibility in

The DS28E07 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

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. The

communication follows the 1-Wire protocol with the ROM

ID acting as node address in the case of a multiple-device

1-Wire network.

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 Hysteresis and Filtering to Optimize

Performance in the Presence of Noise

• Communicates to Host with a Single Digital Signal

at 15.4kbps or 125kbps Using 1-Wire Protocol

• Reads and Writes over a Wide Voltage Range from

3.0V to 5.25V from -40°C to +85°C

Applications

● Accessory/PCB Identiﬁcation

● Medical Sensor Calibration Data Storage

● Analog Sensor Calibration Including IEEE P1451.4

Smart Sensors

● Ink and Toner Print Cartridge Identiﬁcation

● After-Market Management of Consumables

• ±8kV HBM ESD Protection (typ) for IO Pin
