LPC47B272中文资料Super I/O Controller数据手册Microchip规格书

描述 Description

TheLPC47B272 (AMI Keyboard BIOS version of the LPC47B27x) is a 3.3V PC98/PC99compliant Super I/O controller. It implements the LPC interface and providesfan control through two fan speed control output pins and two fantachometer input pins.Itstrue CMOS 765B core provides 100% compatibility with IBM PC/XTTM andPC/ATTM architectures in addition to providing data overflowand underflow protection. Sophisticatedpower control circuitry (PCC) incorporated for keyboard, mouse andconsumer infrared wake-up events support, aswell as multiple low power-down modes. Software Configurable Logic (SCL) is incorporatedby the FDC37C669 Floppy Disk Controller for ease of use, which doesn’t requireany external filter components. Software and register compatible withSMSC's proprietary 82077AA core. The parallel port is compatible with IEEE1284, EPP, and ECP. The I/O Address, DMA Channel and hardware IRQ ofeach logical device in the LPC47B272 may be reprogrammed through theinternal configuration registers. Therecommended functionality to support Windows '95 is provided.Family partsLPC47B272-MS
