What is iButton Reading/Writing via 1-Wire Interface about?

This document discusses reading and writing to iButton devices via serial interfaces. iButtons are small data storage chips housed in stainless steel casings that communicate over a single data line plus ground. There are various iButton devices that differ in memory type (NVRAM, EPROM), capacity (512 bits to 64kb), and additional features like real-time clocks. To read iButtons, a 5kΩ pull-up resistor is used to supply power. Writing requires pulses between 15us and 60us for bits and up to 12V for programm
