3 / 152 page 3 GENERAL DESCRIPTION The SMSC FDC37C665GT and FDC37C666GT Advanced High Performance Multi-Mode Parallel Port Super I/O Floppy Disk Controller ICs utilize SMSC's proven SuperCell technology for increased product reliability and functionality. The FDC37C665GT is optimized for motherboard applications while the FDC37C666GT is oriented towards controller card applications. Both devices support 1 Mb/s data rates for vertical recording operation. The FDC37C665GT is hardware compatible with the FDC37C651 and FDC37C661 in the Standard and Enhanced Parallel Port Modes. The FDC37C665GT and FDC37C666GT incorporate 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 which includes ChiProtect circuitry plus EPP and ECP support, IDE interface, on-chip 24 mA AT bus drivers, game port chip select (FDC37C666GT only), general purpose address decoder and four 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 NS16C550. The parallel port, the IDE interface and the game port select logic are compatible with IBM PC/XT and PC/AT architectures, as well as EPP and ECP. The FDC37C665GT and FDC37C666GT incorporate sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes. The FDC37C665GT Floppy Disk Controller incorporates Software Configurable Logic (SCL) for ease of use. Use of the SCL feature allows programmable system configuration of key functions such as the FDC, parallel port, and UARTs. The parallel port ChiProtect prevents damage caused by the printer being powered when the FDC37C665GT or FDC37C666GT is not powered. The parallel port backdrive current protection prevents the FDC37C665GT or FDC37C666GT from sinking current when the device is powered off and the printer is left powered on. The FDC37C665GT and FDC37C666GT do not require any external filter components and are, therefore, easy to use and offer lower system cost and reduced board area. The FDC37C665GT and FDC37C666GT are software and register compatible to the 82077AA using SMSC's proprietary floppy disk controller core. IBM, PC/XT and PC/AT are registered trademarks and PS/2 is a trademark of International Business Machines Corporation.
