Device Overview

Summary

LPC47N237 is a 3.3V (5V Tolerant) PC99a/PC2001 compliant Docking I/O controller. The device implements the LPC interface, includes I/O functionality. LPC47N237’s LPC interface supports LPC I/O and DMA cycles. There is also an SMBus hosted GPIO Block. 

The legacy I/O included in the LPC47N237 are: a 16C550A compatible UART; one Multi-Mode parallel port including ChiProtectTM circuitry plus EPP and ECP. The parallel port is compatible with IBM PC/ATTM architecture, as well as IEEE 1284, EPP and ECP. LPC47N237 incorporates sophisticated power control circuitry (PCC) which includes support for PME. PCC supports multiple low power-down modes. The I/O Address, DMA Channel and hardware IRQ of each logical device in the LPC47N237 may be reprogrammed through the internal configuration registers.
