The DS1961S-F5+ is a specialized iButton device from Analog Devices / Maxim Integrated, designed for secure data storage and authentication. It incorporates 1128 bits of EEPROM memory, partitioned into four pages, along with a 64-bit write-only secret and up to five general-purpose read/write registers.
This iButton features an on-chip 512-bit SHA-1 engine for computing 160-bit MACs and generating secrets, enhancing security for write access which requires knowledge of the secret and a valid MAC. Data integrity is further protected by an on-chip 16-bit Cyclic Redundancy Check (CRC) generator.
Operating over a wide voltage range of 2.8V to 5.25V and an industrial temperature range of -40°C to +85°C, the DS1961S-F5+ is built for demanding environments. It communicates using the single-digital-signal 1-Wire protocol at standard speeds of 14.1kbps, with an overdrive mode boosting communication to 125kbps. The device offers a minimum of 10 years of data retention at +85°C.
