The SMSC FDC37C665IR has a 3 Volt Advanced High Performance Multi-Mode Parallel Port Super I/O Floppy Disk Controller ICs with Infrared Support utilize SMSC's proven SuperCell technology for increased product reliability and functionality. The FDC37C665IR is optimized for motherboard applications. Both devices support 1 Mbps data rates for vertical recording operation.
The FDC37C665IR 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 which includes ChiProtect circuitry plus EPP and ECP support, IDE interface, onchip 12 mA AT bus drivers and three 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. One UART includes additional support for a Serial Infrared Interface, complying with IrDA, HPSIR, and ASKIR formats (used by Sharp, Apple Newton, and other PDAs). 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 FDC37C665IR incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes.
The FDC37C665IR 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 FDC37C665IR is not powered.
The FDC37C665IR does not require any external filter components and are, therefore, easy to use and offer lower sy
