Description

The FDC37C672 with Consumer IR and IrDA v1.1 support incorporates a keyboard interface, SMSC's true CMOS 765B floppy disk controller, advanced digital data separator, two 16C550 compatible UARTs, one Multi-Mode parallel port which includes ChiProtect circuitry plus EPP and ECP, on-chip 24 mA AT bus drivers, two floppy direct drive support, Intelligent power management and SMI support. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures in addition to providing data overflow and underflow protection.  The SMSC advanced digital data separator incorporates SMSC's patented data separator technology, allowing for ease of testing and use.  Both on-chip UARTs are compatible with the NS16C550.  The parallel port is compatible with IBM PC/AT architecture, as well as IEEE 1284 EPP and ECP.  The FDC37C672 incorporates sophisticated power control circuitry (PCC).  The PCC supports multiple low power down modes.

The FDC37C672 supports the ISA Plug-and-Play Standard (Version 1.0a) and provides the recommended functionality to support Windows '95.  The I/O Address, DMA Channel and Hardware IRQ of each logical device in the FDC37C672 may be reprogrammed through the internal configuration registers.  There are 480 I/O address location options, 8 parallel IRQs, an optional Serialized IRQ interface, and three DMA channels.

The FDC37C672 does not require any external filter components and is therefore easy to use and offers lower system costs and reduced board area.  The FDC37C672 is software and register compatible with SMSC's proprietary 82077AA core.
