AES 128 in hardware under a buck

AES 128 in hardware under a buck
I'm currently working with low power radios in consumer electronics.
Zigbee/RF4C, Bluetooth low energy, etc.

The interesting thing is that there are chips which contain a processor,
a 2.4GHz radio, and AES 128 in hardware.
For a few bucks or less. Going into things like TV remote controls.
Great for protecting your keystrokes on a qwerty remote control when
using TV like a computer. Makes you wonder about AES 128. ....
Also, adding a microphone (think Siri voice control) is becoming commonplace.
Which can be fun but the microphone is in a system which can be
manipulated.
As someone (DIRNSA ?) recently said, folks are bugging themselves.*
At least certain Sun workstations of old turned on an LED when the microphone
was enabled. ....
It is now trivial to make a bursted, encrypted audio bug the size of the
battery plus a little.
