Description
●The DS28EC20 is a 20480-bit, 1-Wire® EEPROM organized as 80 memory pages of 256 bits each. An additional page is set aside for control functions. Data is written to a 32-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, blocks of eight memory pages can be write protected or put in EPROM-Emulation mode, where bits can only be changed from a 1 to a 0 state. The DS28EC20 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number. The registration number is used to address the device in a multidrop 1-Wire net environment.
