5 MSP430FR2355 Microcontroller & User Interface

The MCF8316DEVM includes the MSP430FR2355 low-power MCU (as shown in Figure 5-1) to communicate via I2C with the MCF8316. The MSP430FR2355 is, by default, flahsed with the firmware required to enable communication between the GUI and MCF8316.

To program the MSP430FR2355, an external MSP430 FET programmer, like the eZ-FET Debug Probe, must be connected to the Spy-Bi-Wire (SBW) interface connector J4. Many MSP430 LaunchPad™ provide an onboard eZ-FET Debug Probe that can be jumper-wired to the MCF8316DEVM to flash the firmware into the MSP430FR2355 microcontroller.

The Reset (RST) button at any time to reset and restart the MCU program. Two active-low LEDs, D6 and D7, can be used for debug purposes as well.

Finally, a shunt jumper bridge on the 32-pin connector J6 ties all signals between the microcontroller and MCF8316D. These jumpers can be inserted or removed as needed in order to isolate the microcontroller from the gate driver. This allows for microcontroller signal debugging or using the MCF8316DEVM as a standalone gate driver with an external microcontroller.
