Table 2-9. Communication modules
Module
Description
USB 2.0 compliant module with support for host, device, and On-The-Go modes.
Includes an on-chip transceiver for full and low speeds.
Up to 5 V regulator input typically provided by USB VBUS power with 3.3 V
regulated output that powers on-chip USB subsystem, capable of sourcing 120 mA
to external board components.
Serial peripheral interface (SPI)
Synchronous serial bus for communication to an external device
Inter-integrated circuit (I2C)
Allows communication between a number of devices. Also supports the System
Management Bus (SMBus) Specification, version 2.
Universal asynchronous receiver/
transmitters (UART)
Asynchronous serial bus communication interface with programmable 8- or 9-bit
data format and support of ISO 7816 smart card interface
The I
2
S is a full-duplex, serial port that allows the chip to communicate with a
variety of serial devices, such as standard codecs, digital signal processors
(DSPs), microprocessors, peripherals, and audio codecs that implement the inter-
IC sound bus (I
2
S) and the Intel
®
AC97 standards
Low power UART module that retains functionality in stop modes.
