• Manufacturer Part Number: LPC47N227-MV
• Manufacturer: Standard Microsystems (SMSC)

Specifications of LPC47N227-MV

• Pin Count: 100
• Lead Free Status / RoHS Status: Compliant

100 Pin Super I/O with LPC Interface for Notebook Applications
separator technology allowing for ease of testing and use. The LPC47N227 supports both 1Mbps and 2Mbps data
rates and vertical recording operation at 1Mbps Data Rate.
The LPC47N227 also features a full 16-bit internally decoded address bus, a Serial IRQ interface with PCI nCLKRUN
support, relocatable configuration ports and three DMA channel options. Both on-chip UARTs are compatible with the
NS16C550. One UART includes additional support for a Serial Infrared Interface that complies with IrDA v1.2 (Fast
IR), HPSIR, and ASKIR formats (used by Sharp and other PDAs), as well as Consumer IR.
The parallel port is compatible with IBM PC/AT architectures, as well as IEEE 1284 EPP and ECP. The parallel port
ChiProtect circuitry prevents damage caused by an attached powered printer when the LPC47N227 is not powered.
The LPC47N227 incorporates sophisticated power control circuitry (PCC). The PCC supports multiple low power
down modes. The LPC47N227 also features Software Configurable Logic (SCL) for ease of use. SCL allows
programmable system configuration of key functions such as the FDC, parallel port, and UARTs.
The LPC47N227 supports the ISA Plug-and-Play Standard (Version 1.0a) and provides the recommended
functionaity to support Windows ‘95/’98 and PC99. The I/O Address, DMA Channel and Hardware IRQ of each
device in the LPC47N227 may be reprogrammed through the internal configuration registers. There are 192 I/O
address location options, a Serialized IRQ interface, and three DMA channels.
