I2C Bus is the Inter-Integrated Circuit serial bus developed by Philips Semiconductor for inter-IC communications. Now, this highly efficient and cost effective communications link is being adopted by leading technology companies worldwide for chip, board, and system level communications.

An I2C Bus network can support up to 127 Master or Slave devices with a 2-wire serial interface. I2C devices can be as simple as RAM, EEPROM, or I/O devices, or have the full-blown processing power of an embedded microcontroller or microprocessor.

Start sending I2C messages in minutes using our Message Manager or Message Center applications included with each adapter.
