2.5 MSP430FR2355 Microcontroller

The MCF8315RRYEVM includes the MSP430FR2355 low-power MCU (as shown in Figure 2-5) to communicate via I2C with the MCF8315 IC.

To program the MSP430FR2355, an external MSP430 FET programmer must be connected to the Spy-Bi-Wire (SBW) interface connector J4. Many MSP430 LaunchPads™ provide an onboard eZ-FET Debug Probe that can be jumper-wired to the MCF8315RRYEVM to flash the firmware into the onboard MSP430FR2355 microcontroller.

The user can use the Reset (RST) S4 button at any time to restart the MCU program. Two active-low LEDs, D6 and D7, can be used for debug purposes as well.

The 32-pin shunt jumper bridge J6 ties all signals between the microcontroller and MCF8315 IC. 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 MCF8315RRYEVM as a standalone gate driver with an external microcontroller.
