Skystars RC's Kramam KM55 AM32 4-In-1 ESC may be the first commercially available multirotor ESC released with the AM32 firmware. 

The AM32 firmware is designed for STM32 ARM processors to control a brushless motor (BLDC).  The firmware is intended to be safe and fast with smooth fast startups and linear throttle.  It is meant for use with multirotor aircraft and a flight controller.

AM32 is similar to BLHeli_32, except it is open-source.  Join the development at the AM32 Github.
