    I have purchased this item. I need to know how to program this item through microcontroller.

    FSK RF modules are similar to ASK. FSK modules use Frequency Shift Keying while ASK is Amplitude Shift Keying.

    So you can use the same circuit of ASK modules. You can refer this article, Wireless RF Transmitter and Receiver using ASK Modules.

    I hope that you already know about ASK modules and its usage. These FSK modules are commonly used for replacing traditional ASK modules for better noise immunity and performance.

    It is very easy to integrate with a microcontroller. If you check the circuit you can see that the inputs (to HT12E) and outputs (HT12D) are digital. So you can connect it to any microcontroller and do normal IO operations.

    Here you can see a sample project done using ASK modules. Same is applicable to FSK also, just by replacing the module.
