NXP® continues its leading position in I2C-bus devices, offering you a vast portfolio of I2C logic products used for communication and protocol conversion.Our I2C solutions are ideal for many systems using SMBus, AdvancedTCA (ATCA) IPMI, and PMBus. You can also choose from a comprehensive selection of other semiconductor ICs with I2C-bus interfaces.
NXP's new I2C Fast-mode Plus (Fm+) devices go from zero to 1 MHz so you can go to the next design level with higher data rates and up to 540 pF bus loading. In computing, telecom and networking systems architecture the trend is for greater use of I2C-bus as a maintenance and control bus, so more bandwidth and more devices on the bus is required.
The I2C-bus appears in virtually every application. In cellular handsets, LED blinkers and dimmers can control keypad, fun lighting and status LEDs. These ICs can also be used for more advanced status or illumination control while off-loading host processors in LCD displays. LCD segment or LCD matrix drivers with an I2C interface are ideal for cordless telephone handsets.
I2C serial EEPROM can store preset information in an MP3 player or large LCD display, where PAL or NTSC settings during manufacture are set using I2C DIP switches. For environmental sensing, I2C temperature sensors can monitor local temperatures: particularly important in wireless basestations, where I2C repeaters / hubs / extenders are also used, to isolate capacitance from the backplane.
