I/O Controller 0.04A 128-Pin PQFP

The FDC37B72x incorporates a keyboard interface, SMSC"s true CMOS 765B floppy disk controller, one Multi-Mode parallel port which includes ChiProtectTM circuitry plus EPP and ECP support, soft power management and SMI support and Intelligent Power Management including PME and SCI/ACPI support. The true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures in addition to providing data overflow and underflow protection. Both on-chip UARTs are compatible with the NS16C550A. The parallel port is compatible with IBM PC/ATTM architecture, as well as EPP and ECP. The FDC37B72x incorporates sophisticated power control circuitry (PCC) which includes support for keyboard, mouse, modem ring, power button support and other wake-up events. The PCC supports multiple low power down modes. The FDC37B72x provides for the recommended functionality to support Windows "95/’98 and PC98/PC99. Through internal configuration registers, each of the FDC37B72x"s logical device"s I/O address, DMA channel and IRQ channel may be programmed.
