The MCT8316A family of devices supports two different interface versions, I²C (MCT8316AV) and hardware (MCT8316AT) to provide end application design suited for either flexibility or simplicity. The two interface versions share the same 40-pin VQFN package with significant overlap in power and certain I/O pins (like FG, nFAULT, DIR, BRAKE, SPEED/WAKE) positions - this compatibility lets application designers evaluate with one interface version and potentially switch to another with minimal modifications to their design. The I²C version (MCT8316AV) allows controlling the motor operation and system through BRAKE, DIR, DRVOFF, EXT_CLK, EXT_WD and SPEED/WAKE . MCT8316AV also provides different signals for monitoring algorithm variables, speed, fault and phase current feedback through DACOUT1, DACOUT2, FG, nFAULT and SOX. The hardware version (MCT8316AT) allows controlling the motor operation and system through BRAKE, DIR, SPEED/WAKE, DRVOFF and allows configuring system/algorithm parameters through CONFIG_1, CONFIG_2, CONFIG_3, LDANGLE, ILIMIT, RMP_1, RMP_2, SLEW_RATE. MCT8316AT also provides different signals for monitoring speed and fault feedback through FG and nFAULT.
