It is functionally compat- ible with the PC87338. It includes a Floppy Disk Controller (FDC), two Serial Communication Control- lers (SCC) for UART and Infrared support, one IEEE1284 compatible Parallel Port, and two general purpose Chip Select signals for game port support. The device supports power management as well as 3.3V and 5V mixed operation making it particularly suitable for notebook and sub-notebook applications. The PC87338 and PC97338 are fully compliant to the Plug and Play specifications included in the "Hard- ware Design Guide for Microsoft Windows 95". Differences between the PC87338 and PC97338 are indicated in italics. These differences are summarized in Appendix A. Features s Meets ACPI 1.0 and PC98/99 requirements s Backward compatible with PC87338 s 100% compatibility with Plug and Play require- ments specified in the “ Hardware Design Guide for Microsoft Windows 95”, ISA, EISA, and Micro- Channel architectures s A special Plug and Play module includes: — Flexible IRQs, DMAs and base addresses — General Interrupt Requests (IRQs) that can be multiplexed to the ten supported IRQs November 1998 PC87338/PC97338 ACPI 1.0 and PC98/99 Compliant SuperI/O TRI-STATE® is a registered trademark of National Semiconductor Corporation.
