LPC47M107S-MS

Product Summary

The LPC47M10x* is a 3.3V (5V tolerant) PC98/PC99 compliant Super I/O controller. The LPC47M10x implementsthe LPC interface, a pin reduced ISA bus interface which provides the same or better performance as the ISA/X-buswith a substantial savings in pins used. The LPC47M10x provides fan control through two fan speed control outputpins and two fan tachometer input pins. It also provides 37 general purpose input/output (GPIO) pins, a dual gameport interface and MPU-401 MIDI support.The LPC47M10x incorporates a keyboard interface, SMSC's true CMOS 765B floppy disk controller, advanced digitaldata separator, two 16C550A compatible UARTs, one Multi-Mode parallel port which includes ChiProtect circuitry plusEPP and ECP, on-chip 12 mA AT bus drivers, one floppy direct drive support, and Intelligent Power Managementincluding PME support. The true CMOS 765B core provides 100% compatibility with IBM PC/XT and PC/ATarchitectures in addition to providing data overflow and underflow protection. The SMSC advanced digital dataseparator incorporates SMSC's patented data separator technology, allowing for ease of testing and use. Both on-chip UARTs are compatible with the NS16C550A.
