4.3 MSP430FR2355 Microcontroller & User Interface
The MCF8315EVM includes the MSP430FR2355 low-power MCU (as shown in
) to communicates via
I2C with the MCF8315.
In order 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 MCF8315EVM 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, 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
MCF8315. 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 MCF8315EVM as a standalone gate
driver with an external microcontroller.
