Chipcon/TI CC1110 radio transceiver


In early spring 2006 Chipcon (Texas Instruments today) announced a very promising ISM radio transceiver device. Today first people are getting hold of the CC1110:

cc1110f32

Nick Chernyy has taken a series of great shots of the CC1110. In his microblog he's doing silicon porn pics every friday (aka IC Friday).
All kudos go to Nick!

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.
