UCB1400

The UCB1400 is a stereo audio codec equipped with touch screen and power management interfaces. It integrates an AC '97 Rev. 2.1 interface for communication to an AC link host controller such as the Intel Xscale™ processor. The UCB1400 stereo audio codec inputs connect directly to a microphone or line level sources such as a CD player. The stereo audio codec outputs at line level and can drive a headphone directly. The UCB1400's touch screen interface connects directly to a 4-wire resistive touch screen. A built-in 10-bit analog-to-digital converter provides readout of touch screen and power management parameters. Ten general-purpose I/O pins of UCB1400 provide programmable inputs and/or outputs to the system.
