CMI 110: ACT8870QJ110-T

CMI 110 is optimized for the Starblaze STAR1000/STAR1000P M.3, U.2, and AIC form factor solid state disk (SSD)

drive controllers. It is designed to operate from a 3.3V input voltage.

STAR1000 Configuration

The following table shows how to connect the ACT8870QJ110 outputs to the STAR1000/STAR1000P.
