How to choice the MCU?

Hi,

We have the project that require the function as following:

  1. Read/Write TF Card
  2. Play MP3 files read from TF card
  3. Read a string(10 characters) from UART, and searching the match in TF card (30000 * 10 characters)
  4. WiFi (or UART for WiFi)
  5. GPIO * 16 for LED

Which MCU and Evaluation Board are you recommend?

P.S. We use S12ZVCA for many years. I think S12ZVCA is no good for this project.

Best Regards,

Aaron

Hello,

There are a lot of devices that can fit for that description of project that you want to make,  I will suggest the following:

A) i.MX6ULL  --- This device would help with the MP3, SD Card and Wifi support, since it is a multimedia processor, the bad thing it is that you would need an Operating System to handle it, since it is a 32 bits ARM Cortex A9.

B)i.MXRT 1050.  --  This is a 32 bits Microcontroller with an ARM Cortex M7. Very fast for this kind of application, option to have an LCD, programming with an SDK like an Arduino API.

C)LPC55Sxx   This is an ARM Cortex M33 double core. Again the usage of the SDK and bareboard programming.

Hope this helps to take your decision.
