It's not exactly a consumer part, but anyway:
At university we are using a transparent RS-232 RF-Transceiver. It has got
an AT90S8515 on it.
But I really think that is going out at low volumes. I don't recall the
price, but it was certainly more expansive than a walky-talky ;-(
I also believe that they are putting much more money in programming the
firmware than in the parts. And they should be in need of fixing wrong
software without ripping everything apart.
Keyboards and mice are using some controller, but they are certainly OTP or
with ROM-mask. Flash/EEPROM is expensive.
Though it should be cool to make a firmware update on your keyboard ;-)))
So now I'm going to open my Logitech wireless mouse
Motorola LSC429124, google didn't find anything, seems to be custom
No programming socket either ;-)
