Overview

PC87338/PC97338 ACPI 1.
0 and PC98/99 Compliant SuperI/O November 1998 PC87338/PC97338 ACPI 1.
0 and PC98/99 Compliant SuperI/O General Description The PC97338 is a fully ACPI 1.
0 and PC98/99 compliant, ISA based Super I/O.
It is functionally compatible with the PC87338.
It includes a Floppy Disk Controller (FDC), two Serial Communication Controllers (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 "Hardware Design Guide for Microsoft Windows 95".
Differences between the PC87338 and PC97338 are indicated in italics.
These differences are summarized in Appendix A.
