4.3 MSP430FR2355 Microcontroller & User Interface

The MCT8329EVM includes the MSP430FR2355 low-power MCU (as shown in Figure 4-4) to communicates via I2C with the MCT8329.

To program the MSP430FR2355, an external MSP430 FET programmer 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 MCT8329EVM to flash the firmware into the MSP430FR2355 microcontroller.

The user can use the Reset (RST) button at any time to reset and restart the MCU program. Two active-low LEDs, D13 and D14, can be used for debug purposes as well.

Finally, a shunt jumper bridge on the 32-pin connector J9 ties all signals between the microcontroller and MCT8329. These jumpers can be inserted or removed as needed to isolate the microcontroller from the gate driver. This allows for microcontroller signal debugging or using the MCT8329EVM as a standalone gate driver with an external microcontroller.
