K32L2A31VLL1A Schematic/Sample Design

kapil_kesharvan — Tue, 12 May 2020 13:21:18 GMT

Hi,

I want to use the "K32L2A31VLL1A" MCU to develop the design for one of my products. I have gone through the below links.

1. K32L2A31VLL1A Product Information|NXP

2. https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/general-purpose-mcus/k32-l-series-cortex-m4-m0-plus/k32-l2-ultra-low-power-highly-integrated-mcu:K32-L2?fpsp=1&tab=Documentation_Tab

I have gone with some of the documents and evaluation boards but I was not able to get the proper design for the MCU.

Can someone suggest if they have the design for this MCU?

Your support in this regard will be highly appreciable. And Thank you so much in Advance.

Regards

Kapil

Hi Kapil Kesharvani,

Thanks for your interest in the NXP kinetis product, I would like to provide service for you.

K32L2A31VLL1A can refer to the FRDM-K32L2A4S:

FRDM-K32L2A4S Platform | Freedom Development Board | K32 L MCUs | NXP

But, it seems the design file still not put in the nxp website.

Anyway, I will help you to check it with our internal side,apply for upload the related schematic and the design file to the website.

Here I share with you one K32L2A4 schematic at first.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Kerry

Hello Kerry,

Thank you so much for your reply.

Since we are going to finalize this MCU. So it is possible to share the sample design/ Application for the same MCU as soon as possible. And we need some samples and evaluation boards. so how soon we can get this?

As mentioned before, I am going through the datasheet and try to understand the features that we are looking for. But for better clarification can you suggest which pins are good for the below features.

The main features that we are going to use are:

1. SPI (1 no.)

2. I2C (1 no.)

3. UART(1 no.)

4. JTAG Debug

5. GPIOs, (30/40 numbers)

6. Clock, Reset, etc...

Regards

Kapil

Hi Kapil Kesharvani ,

Please check the SDK code for FRDM-K32L2A4S from this link:

https://mcuxpresso.nxp.com/en/select

You will find all the related sample code for the perpherals.

Wish it helps you!

Hi Kerry,

Thanks for the reply. and sharing the inputs.

But my query was related to Schematic design.

it is possible to share the MCU (K32L2A31VLL1A) sample design (Circuit)/ Application design.

The main features that we are going to use are:

1. SPI (1 no.)

2. I2C (1 no.)

3. UART(1 no.)

4. JTAG Debug

5. GPIOs, (30/40 numbers)

6. Clock, Reset, etc...

And we need some samples and evaluation boards. what will be the lead time?

Regards

Kapil

Hi Kapil Kesharvani,

The K32L2A31VLL1A related circuit can refer to the FRDM-K32L2A4S schematic directly.

FRDM-K32L2A4S on board chip is K32L2A41VLL1A, your chip is K32L2A31VLL1A , even the package is the same, just the Flash and SRAM difference:

About the samples, you can apply it from the nxp.com:

You can find it is active now.

About the board, you can refer to the FRDM-K32L2A4S, you can use FRDM-K32L2A4S directly or change the on board chip to K32L2A31VLL1A.

About the peripheral hardware, the same as FRDM-K32L2A4S, you can refer to it directly.

1. SPI (1 no.)

2. I2C (1 no.)

3. UART(1 no.)

4. JTAG Debug

5. GPIOs, (30/40 numbers)

Check the fanout J1,J2, J3,J4 refer to your own design.

6. Clock, Reset, etc...

clock,

reset pin, 4.7K to 10K pullup, and 0.1uf capacitor to ground.

More details, check the FRDM schematic which I give you, you totally can refer to it.

Wish it helps you!

Kerry
