Multi-Mode Parallel Port with ChiProtect - Standard Mode IBM PC/XT PC/AT, and PS/2 Compatible Bidirectional Parallel Port - Enhanced Parallel Port (EPP) Compatible - EPP 1.7 and EPP 1.9 (IEEE 1284 Compliant) - IEEE 1284 Compliant Enhanced Capabilities Port (ECP) - ChiProtect Circuitry for Protection Against Damage Due to Printer Power- On - 480 Address, Up to 15 IRQ and Three DMA Options !" ISA Host Interface - 16 Bit Address Qualification - 8 Bit Data Bus - IOCHRDY for ECP and IrCC - Three 8 Bit DMA Channels - Serial IRQ Interface Compatible with Serialized IRQ Support for PCI Systems - PCI PME Interface !" 100 Pin QFP Package GENERAL DESCRIPTION The FDC37B77x with advanced Consumer IR and IrDA v1.0 support incorporates a keyboard interface, SMSC's true CMOS 765B floppy disk controller, advanced digital data separator, two 16C550A compatible UARTs, one Multi-Mode parallel port which includes ChiProtect circuitry plus EPP and ECP, on-chip 12 mA AT bus drivers, one floppy direct drive support, and Intelligent Power Management including PME 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 NS16C550A. The parallel port is compatible with IBM PC/AT architecture, as well as IEEE 1284 EPP and ECP. The FDC37B77x incorporates sophisticated power control circuitry (PCC) which includes support for keyboard, mouse, modem ring and consumer infrared wake- up events. The PCC supports multiple low power-down modes. The FDC37B77x 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 FDC37B77x may be reprogrammed through the internal configuration registers. There are 480 I/O address location options, a Serialized IRQ interface, and three DMA channels. The FDC37B77x does not require any external filter components and is therefore easy to use and offers lower system costs and reduced board area. The FDC37B77x is software and register compatible with SMSC's proprietary 82077AA core. |
