DS28E80 is a user-programmable nonvolatile memory chip. In contrast to 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 organised in blocks of 8 Bytes. Individual blocks can be write-protected, and each memory block can be written eight 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.
You can use the device for identification and calibration of medical sensors, tools and accessories, and identification of medical consumables.
