4.7 MCT8316Z0R Compatibility

The MCT8316ZTEVM is also compatible with the MCT8316Z0R (SPI variant) as the featured motor driver IC to spin a three-phase Brushless-DC motor. The MCT8316Z0R replaces the MODE, ADVANCE, SLEW, and VSEL_BK pins with four SPI pins (SDI, SDO, SCLK, nSCS) to configure control registers and read status registers. When using the MCT8316Z0R:

  • SPI enable resistors in the “Depop. if H/W” silk screen box are to be populated (R13-R16)

  • "Pop. If H/W" resistor (R17) is to be depopulated

  • Resistor dividers in the “Hardware Variant Resistors” silk screen box are to be depopulated (R19-R22, R26-R29).

Table 4-4 and Figure 4-7 show the status of populated and DNP resistors for the two compatible MCT8316Zx variants.
