1-Wire bus is a communication system developed by Dallas Semiconductor. It is quite similar to I2C, except for the data rate, which is lower, the costs, which are very low, and the range, which is higher. The 1-Wire protocol allows the communication among several devices produced by Dallas Semiconductors/Maxim, such as:
* temperature, humidity, and pressure sensors, thermocouples
* LCD, counters
* eeprom and rom memory, encryption (IP protection)
* identification devices (electronic keys)
The main applications of 1-Wire devices are as follows:
* Print Cartridge ID
* Medical Consumable ID
* Rack Card Calibration and Control
* Printed Circuit Board (PCB) identification and authentication
* Accessory/Peripheral Identification and Control
* IP Protection, Secure Feature Control, Clone Prevention
* Consumer electronics
* Access control
* Electronic cash
* Gaming devices
