Notebook I/o Controller With Enhanced Keyboard And System Control

The FDC37N958FR is compliant with ACPI 1.0 and PC 97 and incorporates an 8051 based keyboard controller; a Flash Interface; four PS/2 ports; real-time clock; SMSC's true CMOS 765B FDC with advanced digital data separator and 16 byte data FIFO; two 16C550A compatible UARTs the second UART contains a Synchronous Communications Engine to provide for IrDA Ver 1.1 (Fast IR) compliance; one Multi-Mode parallel port which includes ChiProtect TM circuitry plus EPP and ECP support; 8584 style Access Bus interface; Serial IRQ peripheral agent interface; General Purpose I/O; Two independent pulse width modulators; on-chip 24 mA AT bus drivers and two floppy direct drive 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 EPP and ECP. The 8051 controller CAN also take control of the parallel port Interface to provide remote diagnostics or Flashing of the Flash memory. The FDC37N958FR has three separate power planes which allows it to provide instant on and system Power Management functions. Additionally, the FDC37N958FR incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The FDC37N958FRs configuration Register set is compatible with the ISA Plug-and-Play Standard (Version 1.0a) and provides the functionality to support Windows '95. Through internal configuration Registers each of the FDC37N958FR 's logical device's I/O address, DMA channel and IRQ channel may be programmed. There are 480 I/O address location options, 13 IRQ options, and 4 DMA channel options for each logical device. The FDC37N958FR does not require any external Filter components and is, therefore, easy to use and offers lower system cost and reduced board area. The FDC37N958FR is software and Register compatible with SMSC's proprietary 82077AA core. By Unkown
