DS28E80Q+T

DS28E80Q+T is a gamma radiation-resistant 1-wire memory. It is a user-programmable non-volatile 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 248bytes of user memory that are organized in blocks of 8bytes. 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. The 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 a node address in the case of a multiple-device 1-wire network. Typical applications include identification of medical consumables, identification and calibration medical tools/accessories.
