Board Space and Enhances Reliability
- Unique Factory-Programmed, 64-Bit Identification Number
- 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
- ±8kV HBM ESD Protection (typ) for IO Pin
- 6-Pin TDFN Package
The DS28E80 is a user-programmable nonvolatile memory 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 follows the 1-Wire protocol with a 64-bit registration number acting as node address in the case of a multiple-device 1-Wire network.
Applications
- Identification and Calibration Medical Tools/Accessories
- Identification of Medical Consumables

Evaluation System for DS28E80
Product Detail
The DS28E80 evaluation system (EV system) consists of a single evaluation kit (EV kit) that includes a package of five DS28E80 devices in a 6-pin TDFN package, a DS9120Q+ socket board with RJ11 cable, and a DS9481R-3C7+ USB-to-1-Wire®/iButton® adapter with USB cable for PC connectivity. This EV system provides the special hardware and software system to exercise the features of the DS28E80. The evaluation software runs under Windows® 8, Windows 7, Windows Vista®, and Windows XP® operating systems (32-bit and 64-bit versions). It provides a handy user interface to exercise the DS28E80 features.
