    Observe the following cautions and warnings as printed on the EVM board. HOT SURFACE: Caution Hot Surface! Contact may cause burns. Do not touch. Please take the proper precautions when operating. MCF8315EVM Evaluation Module SLLU362 – DECEMBER 2022 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated...
  • Page 3: Introduction

    This document serves as a startup guide to supplement the MCF8315EVM. It is intended for engineers to design, implement, and validate reference hardware for the MCF8315 device.
  • Page 4: Quick Start Guide

    3 Quick Start Guide The MCF8315EVM requires a power supply source, which has a recommended operating range from a 4.5-V to 35-V. To setup and power the EVM, follow the sequence below: 1. Connect motor phases to A, B, C on connector J8.
  • Page 5: Hardware And Software Overview

    4.2 Connection Details Figure 4-2 shows the connections made to the MCF8315EVM in order to spin a 3-phase sensorless Brushless- DC motor. An 4.5-V to 35-V power supply or battery is connected to the VBAT or VM and PGND terminals on connector J7.
  • Page 6 Figure 4-2. Connections from Motor to MCF8315EVM Figure 4-3 shows where the micro-USB cable is plugged into the MCF8315EVM to provide communication between evaluation module and GUI. The USB data and 5 V power from the USB is converted into UART data and 3.3 V power to power the MSP430FR2355 microcontroller.
  • Page 7: Msp430Fr2355 Microcontroller & User Interface

    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.
  • Page 8: Led Lights

    4.4 LED Lights The MCF8315EVM has 6 status LEDs implemented that provide the status of power supplies and functionalities of the evaluation module. By default, the VM LED and 3.3 V Buck LEDs will light up when the board is powered and the program has been flashed onto the microcontroller.
  • Page 9: User-Configurable Settings

    Hardware and Software Overview Figure 4-5. MCF8315EVM LEDs 4.5 User-Configurable Settings The MCF8315EVM includes a variety of user-selectable jumpers, switches, and resistors on the entirety of the evaluation board to configure settings. Table 4-2 summarizes all of these configurable settings.

  • Page 11: Hardware Setup

    Hardware Setup 5 Hardware Setup The hardware required to run the motor is the MCF8315EVM, a Micro-USB cable, and a power supply with a DC output from 4.5-V to 35-V. Follow these steps to start up the MCF8315EVM: 1. Connect the DC power supply to header J7. Connect to VBAT and PGND to apply reverse polarity protection and the pi filter to the EVM.
  • Page 12: Mcf8315 Gui Application

    6 MCF8315 GUI Application The MCF8315EVM includes a USB-UART interface, using a MSP430FR2355 microcontroller, that serves as a communication bridge between a host PC and the MCF8315 device for configuring various device settings and reading fault diagnostic information. A MCF8315A GUI is available to interface with and configure the MCF8315 using this communication interface.
