LPC47N267-MV - Brand New Microchip Technology Interface - Specialized
-
GENERAL DESCRIPTION
The SMSC LPC47N267 is a 3.3V PC 99 and ACPI 1.0 compliant Super I/O Controller. The LPC47N267 implements an LPC interface, a pin reduced ISA interface, for supported I/O and DMA cycles. In addition, this part includes an XBus interface that may be accessed through the LPC interface for supported I/O cycles (memory cycles are not supported by this device). The X-Bus interface supports as many as four external components and it offers three different modes of operation for interfacing with these components. The X-Bus interface has an added “Write Protect” feature that ensures that the Base Address and disable bit for each component can only be set by the BIOS to prevent corruption by any virus software. This part also includes 29 GPIO pins.
