I had designed a board for the transceiver back in last spring and am still awaiting the first samples. The CC1110 main features are:
315/433/868/915 MHz GFSK radio
8051 CPU @ 24 MHz (@1 instruction per cycle, not 12:)
128 bit AES coprocessor
32 kB flash
4 kB SRAM
5 channel DMA engine
The board I designed couples the CC1110 via a FTDI to a USB host PC. For the RF part I still need to design a power amp board, as I am targetting a small frequency slot between 869.40 and 869.65 MHz, where (atleast) in germany we're allowed to operate at 500 milliwatts ERP.
A far-in-the-future target of this spare time work will be an encrypted ad-hoc radio network layer.
If I made you curious, just wait for more to come.
If you're an enthusiastic developer, contact me, I may need your help.
