CC2530

The CC2530 is an SoC (System on Chip) radio.  It has an 8051 micro processor built into it to control the radio.  You cannot control the radio directly from a host processor, you must write code on the 8051 to manage communications between the host processor and the CC2530 radio.  The interface can be either RS232 or SPI.

The TX and RX functionality will be what ever your 8051 code provides to the host processor.  If that is all you need then that is all you need to implement.

You should be able to interface it to any ARM processor which has an RS232 UART or SPI port to hook up to the CC2530.

If you don't want to write code on the CC2530's 8051 processor, you might try the CC2520 RF front end.  This part has no micro processor built into it and all the radio control is accomplished via a SPI bus and the radio operations are managed on the host processor.
