1 / 3 page © 2006 Winbond Electronics Corporation www.winbond.com Product Brief December 2006 Revision 1.0 WPCN385L LPC-to-LPC Switch, Fast Infrared Port, Serial Port and GPIOs General Description The WPCN385L, a member of the Winbond LPC SuperI/O family, is targeted for a wide range of portable applications. The WPCN385L is PC2001 and ACPI compliant, and fea- tures an LPC-to-LPC Switch with hot plugability, a Fast Infra- red port (FIR, IrDA 1.1 compliant), Serial Port and General- Purpose Input/Output (GPIO) support for a total of 18 ports. The WPCN385L enables glueless implementation of an LPC-to-LPC Switch between the motherboard LPC bus and the Docking Station, and supports hot insertion and hot re- moval. Outstanding Features ■ Pin and software compatible with the Winbond 87382 ■ LPC-to-LPC Switch with hot plugability, enables LPC devices in the Docking Station to be connected to the Main LPC Bus, thus reducing the number of signals re- quired through the Docking Station connector ■ Fast Infrared Port (FIR) ■ Serial Port ■ LPC bus interface, based on Intel’s LPC Interface Specification Revision 1.1, August 2002 (supports CLKRUN and LPCPD signals) ■ PC2001 and ACPI Revision 3.0 compliant ■ 18 GPIO ports, including 11 with IRQ assertion capa- bility ■ Two testability modes (XOR Tree and TRI-STATE® device pins). ■ 5V tolerant and back-drive protected pins (except LPC bus pins) ■ 48-pin LQFP package LPC Bus South Bridge TPM SIO Portable Platform Docking Station Docking LPC Bus I/O Ports EC DCLKOUT Serial Interface WPCN385L FIR Interface (WPCN8738xU, 8739x) (WPC876xL) (WPCT200) System Block Diagram |
