Serial IO

The I2C module in the LPC54100 is specifically designed for sensor applications. Each of the three I2C ports can operate at up to 3.4 Mega bits per second (Mbits/sec) in slave mode. This mode is especially useful in a system with an Application Processor. The I2C port can also wakeup the CPU on address match when it is operating in a slave mode. This feature is again useful in a system with an Application Processor. Finally, as discussed in the previous slide, the I2C module can operate separately from the CPU clock, further reducing the power consumption.
