MR10Q010-EVAL1 MRAM Evaluation Board

The MR10Q010-EVAL1 MRAM evaluation board from Everspin is an acces-

sory board that is designed to work with the NUCLEO-L476RG MCU evalua-

tion board from ST Microelectronics.

The Evaluation Board

The MR10Q010-EVAL1 is populated with an Everspin 1Mbit Quad SPI

MRAM suitable for evaluating any of the following Everspin Ordering Part

Numbers:

Everspin OPN Density Temperature Grades Package

MR10Q010SC 1 Mbit Commercial (0 - 70°C) 16-SOIC

MR10Q010CSC 1 Mbit Industrial (-40 - 85°C) 16-SOIC

MR10Q010MB 1 Mbit Commercial (0 - 70°C) 24-BGA

MR10Q010CMB 1 Mbit Industrial (-40 - 85°C) 24-BGA

Host Board Support

The MR10Q010-EVAL1 Quad SPI MRAM Evaluation board is designed to connect to the MORPHO connec-

tors on the NUCLEO-L476RG evaluation board from ST. The NUCLEO-L476RG uses an STM32L476RGT6 ARM

Cortex-M4 CPU that includes a exible Quad SPI peripheral connected to the MORPHO connector pins.

The MR10Q010-EVAL1 board includes a high speed bi directional level translator (TXB0106PWR) in order to

shift the I/O level from 3.3V used by the STM32L476RGT6 to the 1.8V required by the MR10Q010. See Ap-

pendix A – MR10Q010-EVAL1 Schematic and Layout for more details.

Step 1: Download and Install the ST-LINK/V2 Driver

Host Board Link to Driver Download Page

NUCLEO-L476RG Link

First, plug the SPI Evaluation board into your MCU host board, then connect the

host board to your PC using the USB cable. The MCU host board will enumerate

as a composite USB device that includes a built in debugger, storage device and

a virtual com port.

A new drive will be created on your computer with a drive name as assigned by

the host board.

Besides the ST Micro MCU host board and the Everspin MR10Q010 Quad SPI Evaluation board, you will need:

• A computer with Internet access and a USB port.

• A USB cable, with standard A to mini B connectors.

Step 2: Plug in the Quad SPI Evaluation board and connect it to your computer via the USB

port.

Everspin Quad SPI MRAM Evaluation Board User Guide

1. Log in to developer.mbed.org. (If you do not already have an mbed account, you will need to cre-

ate one.)

2. After logging in, click on the Compiler button on the upper right section of the screen.

3. The mbed compiler will bring up the Workspace Management screen.

Step 3: Log in to ARM mbed and create a Workspace on your computer.

Setup (Continued)

MR10Q010-EVAL1

Everspin Quad SPI MRAM Evaluation Board User Guide

1. The button on the upper right of the Workspace Management screen will read No device selected

or, if you have previously loaded a platform, the name of the host board for that platform will appear,

as in the NUCLEO-L476RG case shown.

2. In either case, click on the button to open the available compiler platforms screen. Select the host

board platform you wish to load or, if it is not present, then select Add.

3. Adding a platform to your Workspace. If you selected Add, mbed will display a scrolling list of avail-

able platforms. Find the MCU host board you are using and click on the image.

Step 4: Load the platform for the host board you are using

Setup (Continued)

MR10Q010-EVAL1

4. mbed will open a new window as an information page for that host platform, such as the NUCLEO-

L476RG example here. To add this platform to your workspace, click on the Add to your mbed

Compiler button.

5. The platform will be added to your registered platforms list.

Setup (Continued)

Step 5: Import the Everspin MR10Q010-EVAL1 demonstration program from

www.mbed.org to the Program Workspace.

1. In your Workspace, click Import.

2. The Import a program dialog box will open. Click on the Programs tab.

3. Search for“MR10Q010-EVAL1” program, select it and click Import!

4. The demonstration program will now appear in the Program Workspace.

Setup (Continued)

MR10Q010-EVAL1

Step 6: Compile the binary le and and load to your MCU evaluation board.

1. Highlight the MRAM_MR10Q010-EVAL1 program folder in your Program Workspace tree in the left-

hand column.

2. Click Compile in the top menu.

3. The program will be compiled and the binary (.bin) le created will automatically be downloaded to your

computer’s designated download location.

4. Drag and drop the binary le into the host board drive that you created in Step 2. When the le is

dropped into the folder, your MCU host board will begin to program. The LED on you host board may

blink a few times to conrm that the program is loading. When the program is fully loaded, the binary

le will automatically delete from your MCU host board drive.

Setup (Concluded)

Step 1: Use a terminal emulator to run the demonstration.

1. Use your favorite terminal emulator. For this example, we used the Tera Term emulator from SourceForge

at http://en.osdn.jp/projects/ttssh2/releases/.

2. After installing, open Tera Term and select the serial port associated with your host board to create a new

connection.

3. Congure the serial port under Setup->Serial port with: 115200 baud, 8-N-1.

4. Press any key on the keyboard or the Reset button on your MCU host board to run the demonstration

and view the demonstration output on the terminal emulator.

5. The evaluation program demonstrates the following features of the MR10Q010 device:

• Read and decode JEDEC ID

• Tamper detection bits

• Nonvolatile test count

• Performance measurements of SPI, Quad SPI, QPI and XIP modes of operation

You may export the demonstration code to work with other ARM-based toolchains.

1. Once you have the Everspin MR10Q010-EVAL1 example program loaded into ARM mbed you may

export it for development in production ARM tool chains.

2. Right click on the MRAM_MR10Q010-EVAL1 program in the left column of the workspace and select

Export Program.

3. Using Export Target and Export Toolchain in the dialog box, pick the target MCU host board and

Toolchain for export and click on the Export button. The Everspin MR10Q010-EVAL1 example code

will be exported to the tool chain you selected.
