Device Overview

Summary

FDC37B72x provides an integrated keyboard interface, SMSC's true CMOS 765B floppy disk controller, one Multi-Mode parallel port (includes: ChiProtectTM circuitry plus EPP and ECP support), soft power management, SMI support, and Intelligent Power Management (includes: PME and SCI/ACPI support).

CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures in addition to providing data overflow and underflow protection. Both on-chip UARTs are compatible with the NS16C550A. The parallel port is compatible with IBM PC/ATTM architecture, as well as EPP and ECP. This product incorporates sophisticated power control circuitry (PCC) which provides support for multiple low power down modes. It includes keyboard, mouse, modem ring, power button support and other wake-up events.

The device provides for the recommended functionality to support Windows '95/’98 and PC98/PC99. Through internal configuration registers, each of the FDC37B72x's logical device's I/O address, DMA channel and IRQ channel may be programmed.
