WPCN381UA0DG Description

Short technical summary and product information.

The Nuvoton WPCN381UA0DG is a member of the Nuvoton LPC Super I/O family, designed for legacy-reduced, ultra-light portable applications. This component is PC2001 and ACPI compliant, offering essential functions for modern notebook systems.

Key features include a Fast Infrared Port (FIR) that is software compatible with 16550A and 16450 standards and IrDA 1.1 compliant. It also provides two serial ports (SP1 and SP2), with SP2 usable when FIR is not needed, also compatible with 16550A and 16450. The device supports UART data rates up to 1.5 Mbaud.

With 11 General-Purpose Input/Output (GPIO) ports, including 6 with IRQ assertion capability, the WPCN381UA0DG offers flexibility. It utilizes an LPC bus interface based on Intel's LPC Interface Specification Revision 1.1. The device operates on a 3.3V supply, and its pins are 5V tolerant, except for the LPC bus pins. It is available in a 48-pin LQFP package.
