Description

The FDC37C93xAPM(FDC37C935-QS / FDC37C935 ) incorporates a keyboard interface, real-time clock, SMSCs 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 and two floppy direct drive support, as well as ACCESS.bus, soft power management and SMI 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 SMSCs patented data separator technology, allowing for ease of testing and use. Both onchip UARTs are compatible with the NS16C550. The parallel port, the IDE interface, and the game port select logic are compatible with IBM PC/AT architecture, as well as EPP and ECP. The FDC37C93xAPM incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power down modes.
