External RAM on KL25Z

Hello,

I need help to interface an external RAM in KL25Z.

I need to build a buffer with 64kB.

Can anyone help me?

Thanks.

As you know, KL series product has not Flex bus, so it is not suitable to do your application. We recommend Kinetis K series product for you. If you have to use KL25, I think it depends on which function you need. If you need to store data temporary, I think you can use GPIO to simulate. If code, KL25 cannot use in this way.

Hi Monica,

My project is summarized in a speech delay, with the internal memory has managed to make it work for 1 sec.

I need more time, nearly 5 seconds I think to use RAM SPI 23LC1024 to do this, but I have not found in the local market, so I can report the results.
