Hey All,
I'm working on this board which will bridge WIFI to Bluetooth Smart and I've decided pretty much on all the components except the microcontroller 
! I 've been contemplating on this for quite sometime and i could use some help in shortlisting/ finalizing on the microcontroller which could handly both (WIFI and BLE) the stacks and ya..it would help if the microcontroller is as cheap as it can get probably around 5$ or so. Kindly help me out.
The minimum specifications i would like to have on the uC would be:
1. 64 Kb Flash
2. 16 Kb RAM
3. 1Kb EEPROM (optional)
4. USB 2.0 pins (Can probably leave it out if it influences cost a lot)
5. I2C/SPI/UART
6. UltraLowpower
