Optimized MCU

ASIC Success Story


An Industrial customer with a mature system needed to transition an off-the-shelf MCU into an optimized, low-cost and low-power ASIC with a reliable supply chain.  

No longer dependent on the whims of a big MCU supplier, the customer solidified a robust supply chain while also optimizing the silicon for exactly what was needed in the application.
