Must admit i had a brain failure on how much eeprom there was in a microcontroller, for some reason i thought it was much larger.
A buck/boost (integrated switches) like the tps63061 or LTC3115-1 might be a good option, would allow operation from 2.7v up to over 12v.
I took your comment that generating the carrier on the processor was not feasible as a challenge lol. Got some parts on order to give it a try.
Back of the envelope calculations tell me it is possible (16 instruction per data bit. 8 consumed generating the carrier wave, 8 remain to calculate whether to pin toggle). would be ~1600 instructions of pure sequential code (not a single compare or branch).
