Does anyone know of any (reasonably low-cost) SoC which combines all of:

  • Microcontroller (any architecture, at least 4KB RAM/8KB flash)
  • Radio transceiver (433MHz - 915MHz or 2.4GHz)
  • Ethernet MAC + PHY

(For a wireless sensor application - connecting to low power sensor nodes)

I can find examples of micros with either peripheral, but not both:


Micro + ethernet:

LM3S9B9x = ARM Cortex-M3 + Ethernet MAC and PHY

PIC18F66J6x = PIC18 + Ethernet MAC and PHY

Micro + radio:

CC430 = MSP430 + Sub-1GHz radio

EM250 = XAP2b + 802.15.4/ZigBee

Please only answer this question if you can name a chip.

    \$\begingroup\$ I could give you a good example of two chips that would accomplish this but I know of none that do both. \$\endgroup\$ – Michael Eakins Oct 27 '10 at 13:42

    \$\begingroup\$ Maybe I should pull some strings with a friend at TI and have them post a fake part that is the CC430 with ethernet built in. \$\endgroup\$ – Kellenjb Nov 1 '10 at 14:46

    \$\begingroup\$ low power radio AND ethernet seems an odd combination. I don't think it's something that's common enough that there would be profit to be made to build a generic off the shelf part which combines them both. Pretty much any complex device is going to have multiple ICs in it, it's not something to avoid at all costs. \$\endgroup\$ – davr Nov 3 '10 at 4:56

The MediaTek RT3050 has what you need.

Both together I've never seen.

ST has STM32W that integrates a 2.4GHz transceiver and Freescale has MC1322x that integrates ARM7/Coldfire with 2.4GHz transceivers, but both don't have the ethernet PHY.

Not really a chip, but would a Digi ConnectPort be a turnkey solution for what you have in mind? You can run custom software (Python) on them to manage your wireless devices and communicate over Ethernet.
