3 / 147 page SMSC DS – FDC37N869 Page 3 Rev. 11/09/2000 GENERAL DESCRIPTION The SMSC FDC37N869 is a 5v/3.3v PC 99-compliant Super I/O Controller with Infrared support. The FDC37N869 utilizes SMSC’s proven SuperCell technology and is optimized for motherboard applications. The FDC37N869 incorporates SMSC’s true CMOS 765B floppy disk controller, advanced digital data separator, 16-byte data FIFO, two 16C550 compatible UARTs, one Multi-Mode parallel port with ChiProtect circuitry plus EPP and ECP support, game port chip select logic and one floppy direct drive support. The FDC37N869 does not require any external filter components, is easy to use and offers lower system cost and reduced board area. The FDC37N869 is software and register compatible with SMSC’s proprietary 82077AA core. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/AT architectures and provides 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. The FDC37N869 supports both 1Mbps and 2Mbps data rates and vertical recording operation at 1Mbps Data Rate. The FDC37N869 also features a full 16-bit internally decoded address bus, a Serial IRQinterface with PCI nCLKRUN support, relocatable configuration ports and four DMA channel options. Both on-chip UARTs are compatible with the NS16C550. One UART includes additional support for a Serial Infrared Interface that complies with IrDA v1.2 (Fast IR), HPSIR, and ASKIR formats (used by Sharp, Apple Newton, and other PDAs), as well as Consumer IR. The parallel port and the game port select logic are compatible with IBM PC/AT architectures. The parallel port ChiProtect circuitry prevents damage caused by an attached powered printer when the FDC37N869 is not powered. The FDC37N869 incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The FDC37N869 also features Software Configurable Logic (SCL) for ease of use. SCL allows programmable system configuration of key functions such as the FDC, parallel port, and UARTs. |
