It’s not Christmas yet, but: For a research project I’m currently evaluating a new microcontroller where I need a bit more leg room. Right on time I saw that there is a new board available which caught my interest: The Freescale FRDM-K82F :-). Without thinking too much about it, I have ordered that board from Mouser Thursday last week and I had it in my hand today 🙂 Time to put up a quick post about it:
New Box on the table
The board is prices around $50, so more than the $15 I’m used for the FRDM-KL25Z. Well, I’m getting some more for the money too:
- 150 MHz ARM Cortex-M4F
- 256 KByte SRAM
- 2x 32MBit (4 MByte) QSPI memory
- The ‘usual’ push buttons, RGB LED, accelerometer/magnetometer, …
I expected the usual FRDM box, but that board comes in a new (in my view better) box, suitable to put it into a shelf of board.
The package has the usual Quick Reference with a ‘getting started’:
FRDM-K82F Board Content
The board is in a normel anti-static bag (I always tell students to be aware of ESD!). Behind some cardboard, there is a micro USB cable for the board (finally there is such a cable included! I missed that USB cable in the previous FRDM board packages):
FRDM-K82F Box Content
The board has lots of features and most of the header mounted. On the right there are two rows of FLEXIO headers (for a camera? Hmm, thinking now using that board for my Quadrocopter?). On the left side of the CPU there are two QSPI Memory devices (2x32MBit).

FRDM-K82F Bottom Side
Beside of the Arduino headers, I see capacitive touch pads, header for serial bluetooth module, header for nRF24L01+ transceiver :-).
A factory-installed RGB LED demo is running on the board:

That’s it. Now I have the board, and I only need to find more time to actually using it ;-). I will try to find some cycles to explore it more. And I’m willing to borrow the board until then to anyone who is able to show up in my office :-).
Happy Boarding 🙂

What sort of things is the QSPI memory useful for?

I have to check the data sheet of the device first. But typically that kind of things is used for Linux systems too. You can store data and/or run code from it. So it is basically an extension of your program memory.

Hi Erich!
Wow how fast you’ve got it!!!
GND test-hook looks awesome and useful for different logic analyzers. I wish that processors have HS USB like it was in a preview info on frescale cite.
Example running a simple code from QSPIs would be very cool in learning purposes!!! I will wait inpatiently for that:)

Hello Alexey,
You have an example of that currently available in Freescale KSDK 1.3:

Hello Santiago,
Many thanks! Never checked examples for boards I have not got currently. Need to read readme-files better 🙂

Hi,
exist Sram with Quad SPI lowcost ?
thanks,
Carlos.

Depends what ‘low cost’ is for you. But for example there is the Microchip 23LCV1024 1MBit serial SRAM.

Hi Erich,
with 23LCV1024, can execute code with it?
thanks,
Carlos.

Hi Carlos,
I believe so, if you map it to the correct address space. But I have not done that yet. You might have a look at the Freescale TWR-K82 example code too.

You can also connect parallel SRAM memory using flexbus signals which should be available on the headers

Hi Greg, by any chance, is there somewhere a reference design or project for attaching SRAM? I ask because I have an early research project where I need lots of RAM 🙂

Hello Erich,
Did you know that Freedom boards used to feature the processor in a 45 degree angle to mimic Freescale logo? Perhaps today with NxP fusion that is no longer important.
Cheers!
Rafael.

Hi Raphael,
I don’t think this is because of the FSL logo: it is common practice to place devices with many pins in a 45° angle on the board to make it easier to route the pins to all directions.
