This embedded dude longs to use Erlang on his MCUs. Closest I can get to it is one of the embedded *nixes. Raspberry PIs are great for prototyping but not all that easy a sell on the BOM

There's a new mcu from microchip, that has 32mb dram, for ~$7. Might get you closer to your erlang dream.
It uses new , cheap multi-die assembly techniques, which microchip also used in their ~$1 Bluetooth chip. So I think with time, and with an attractive software ecosystem,we'll see interesting new mcu's and price points.

...and a long list of errata, some of them quite serious: http://ww1.microchip.com/downloads/en/DeviceDoc/80000736A.pd...
(note that if you look for it on Microchip website, the official link to the errata is also wrong at the moment!)
Some people also reported a few heat issues, since it's got to dissipate heat from the memory and heat from the MCU, which starts being a bit large and a bit fast (for an MCU). Nothing extreme, but it has has to be considered in some setups.
IMO, it's better to wait for other revisions of this chip, other versions in this family, or something else.
This is quite a list. There are so many "Module x is not functional. Workaround: None." its amazing. How did they manage screw up the VBAT pin?
~$1 Bluetooth chip, is that the ATBTLC1000?
