Status: In Production
LPC47B272 (AMI Keyboard BIOS version of the LPC47B27x) is a 3.3V PC98/PC99
compliant Super I/O controller. It implements the LPC interface and provides
fan control through two fan speed control output pins and two fan
tachometer input pins.
Its true CMOS 765B core provides 100% compatibility with IBM PC/XTTM and PC/ATTM architectures in addition to providing data overflow and underflow protection. Sophisticated power control circuitry (PCC) incorporated for keyboard, mouse and consumer infrared wake-up events support, as well as multiple low power-down modes. Software Configurable Logic (SCL) is incorporated by the FDC37C669 Floppy Disk Controller for ease of use, which doesn’t require any external filter components.
Software and register compatible with SMSC's proprietary 82077AA core. The parallel port is compatible with IEEE 1284, EPP, and ECP. The I/O Address, DMA Channel and hardware IRQ of each logical device in the LPC47B272 may be reprogrammed through the internal configuration registers.
The recommended functionality to support Windows '95 is provided.
