PC87382 is an LPC to LPC switch for docking stations, supporting infrared and serial port.
The PC87382 is an LPC‑to‑LPC switch designed for docking stations, offering hot‑plug capability, a fast infrared (IrDA 1.1) port, a serial port compatible with 16550A/16450 UARTs, and eight general‑purpose I/O ports. It supports PC2001 and ACPI compliance and provides configurable clock sources and protection features such as GPIO lock and pin‑configuration lock.
The document includes a full pin‑out diagram, detailed signal descriptions, power‑up reset sequences, clock domain information, testability options (XOR tree, tri‑state), and extensive electrical characteristics, including timing parameters and package dimensions for the 48‑pin LQFP package.
