LPC47N237中文资料Super I/O Controller数据手册Microchip规格书

描述 Description

LPC47N237is a 3.3V (5V Tolerant) PC99a/PC2001 compliant Docking I/O controller. Thedevice implements the LPC interface, includes I/O functionality.LPC47N237’s LPC interface supports LPC I/O and DMA cycles. There is also anSMBus hosted GPIO Block. 



Thelegacy I/O included in the LPC47N237 are: a 16C550A compatible UART; oneMulti-Mode parallel port including ChiProtectTM circuitryplus EPP and ECP. The parallel port is compatible with IBM PC/ATTM architecture,as well as IEEE 1284, EPP and ECP. LPC47N237 incorporates sophisticated powercontrol circuitry (PCC) which includes support for PME. PCC supportsmultiple low power-down modes. The I/O Address, DMA Channel and hardwareIRQ of each logical device in the LPC47N237 may be reprogrammed throughthe internal configuration registers.
