TheSCH3221-7U is a 3.3V (5V tolerant) PC99/PC2001 compliant I/O controller with anLPC interface. The SCH3221-7U includes 4 full-function serial ports, IrDA andConsumer IR capability, GPIOs and extensive PME Wake support from thesefeatures.The SCH3221-7U is ACPI compatible and supportsmultiple low power-down modes. I/Ofunctionality includes four serial ports. The serial ports are fullyfunctional NS16550 compatible UARTs that support data rates up to 460 Kbps. The PME Wake logic includes the ability to wakefrom a watchdog timer, any of the UART Ring Indicator (RI) inputs, or GPIOs.
