I wonder about the future for the Rabbits. At distributors, a lot of the developemtn boards and RCMs are marked as “not recommended for new designs”.
Here at Digi, when looking at SBC evaluation boards, all Rabbit ones are marked “matured”, while none of the “featured” ones has a Rabbit.
Similar for the µC themselves: E.g. a Digi-Key, the Rabbit 2000 is marked “obsolete”, the Rabbit 3000 “not recommended for new designs”, the Rabbit 5000 is already missing. That only leaves Rabbit 4000 and 6000 as active parts.
Clearly, the Rabbits are rather expensive microcontrollers. I wonder if this is due to old process technology being used? Could a Rabbit 3000 manufactured using a more modern process be more cost-competitive with other µC?
