I2C-bus Controller and Bridge ICs

Continuing our leadership in I2C-bus devices, we offer a vast portfolio of I2C logic products for communication and protocol conversion. These solutions support many systems using SMBus, AdvancedTCA (ATCA) IPMI, and PMBus. These I2C-bus Controllers and Bridges work with I2C, SPI, UART and 8-bit parallel interfaces for applications such as: hardware protocol conversion, when there is no hardware master, or there is a need for a second hardware master.
