DS28E80

DS28E80 EVALUATION KIT AVAILABLE Gamma Radiation Resistant 1-Wire Memory General Description 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.
