The LPC47N237 is a 3.3V (5V tolerant) Super I/O controller designed for docking stations and port replicators, compliant with PC99a/PC2001 standards. It features an LPC interface that supports LPC I/O and DMA cycles, along with a SMBus-hosted GPIO block comprising 32 general-purpose input/output pins. The device includes a full-function 16C550A compatible UART with a programmable baud rate generator and a Multi-Mode parallel port that supports EPP and ECP standards, ensuring compatibility with IBM PC/AT architecture and IEEE 1284. The LPC47N237 incorporates advanced power management capabilities, including multiple low power-down modes and support for PME. It offers extensive configuration options with up to 480 I/O address locations, three DMA channels, and a serialized IRQ interface, making it suitable for a variety of applications requiring flexible I/O solutions. The product is housed in a 100-pin TQFP RoHS compliant package.
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.
