Description
AI
The
SCH3221 is a 3.3V (5V tolerant) PC99/PC2001 compliant I/O controller with an
LPC interface. The SCH3221 includes 4 full-function serial ports, IrDA and
Consumer IR capability, GPIOs and extensive PME Wake support from these
features.
The SCH3221 is ACPI compatible and supports
multiple low power-down modes.
I/O
functionality includes four serial ports. The serial ports are fully
functional NS16550 compatible UARTs that support data rates up to 460 Kbps.
The PME Wake logic includes the ability to wake
from a watchdog timer, any of the UART Ring Indicator (RI) inputs, or GPIOs.
