DS28E80

Gamma Radiation Resistant 1-Wire Memory

General Description

Features and Beneﬁts

● High Gamma Resistance Allows User-Programmable

Manufacturing or Calibration Data Before Medical

Sterilization

The DS28E80 is a user-programmable nonvolatile mem-

ory chip. In contrast to the floating-gate storage cells,

the DS28E80 employs a storage cell technology that is

resistant to gamma radiation. The DS28E80 has 248

bytes of user memory that are organized in blocks of

8 bytes. Individual blocks can be write-protected. Each

memory block can be written 8 times. The DS28E80

communicates over the single-contact 1-Wire® bus at

standard speed or overdrive speed. Each device has its

own guaranteed unique 64-bit registration number that is

factory programmed into the chip. The communication fol-

lows the 1-Wire protocol with a 64-bit registration number

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

1-Wire network.

• Resistant Up to 75kGy (kiloGray) of Gamma Radiation

• Reprogrammable 248 Bytes of User Memory

● Lower Block Size Provides Greater Flexibility in

Programming User Memory

• Memory is Organized as 8-Byte Blocks

• Each Block Can Be Written 8 Times

• User-Programmable Write Protection for Individual

Memory Blocks

● Advanced 1-Wire Protocol Minimizes Interface to

Just Single Contact

● Compact Package and Single IO Interface Reduces

Board Space and Enhances Reliability

• Unique Factory-Programmed, 64-Bit Identiﬁcation

Number

Applications

● Identiﬁcation of Medical Consumables

● Identiﬁcation and Calibration Medical Tools/Accessories

• Communicates at 1-Wire Standard Speed

(15.3kbps max) and Overdrive Speed (76kbps max)

• Operating Range: 3.3V ±10%, -40°C to + 85°C

Reading, 0°C to +50°C Writing

1-Wire is a registered trademark of Maxim Integrated Products, Inc.

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

• 6-Pin TDFN Package
