How to implement Ethernet interface using MSP430FG4619 controller.

MSP controllers don't have Ethernet as far as I know.

For Ethernet enabled MCUs, check the Stellaris

 

As Albert already mentioned, MSP430 MCU's do not have a integrated Ethernet controller.

However, there is a good App Report which describes in detail the implementation of an embedded Web server based on the MSP430 device. The solution consists of both hardware (schematic, parts list) and software (C source). A downsized TCP/IP protocol stack is used. Its functionality is encapsulated by an easy-to-use application programming interface (API). By using this API, creating new applications or modifying existing ones becomes an easy task. As an application example, a dynamic HTTP server is implemented.

Hope This helps,

Is there any MSP series controllers having inbuilt Ethernet support

No. Ethernet and its data sizes are beyond most MSPs capabilities to handle (ram size, speed).

This is very difficult, if possible at all. The MSP does not have an external memory bus like the ATMega or others. So attaching an ethernet controller is difficult and inefficient. I don't say it is impossible, but nobody seems to have bothered doing it.

MSP is ultra-low-power. Ethernet is definitely not. Also, the data storage capabilities of the MSP are so small that ethernet doesn't make any sense too.
