The DS28E05R+U is a 1-wire EEPROM in 3 pin SOT-23 package. It is a 112-byte user-programmable EEPROM organized as 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. Each part has its own guaranteed unique 64bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E05 communicates over Maxim's single contact 1-wire interface at overdrive speed with the ROM ID acting as node address in the case of a multiple-device 1-wire network.
Supply voltage range is 2.75V to 3.63V
Operating temperature range from -40°C to 85°C
Single contact 1-wire interface
Programmable write protection and OTP EPROM emulation modes for user memory
