Difference between PK20DX256Vll7 and MK20Dx256VLL7 MCU part nos?

Dear All,

What is the difference between PK20 and MK20 MCU? the datasheet of MK20DX MCU of 100pins states "it is only the Qualification stage of MCU, P => Pre-qualification stage at the time of mfg/ production and M => fully qualified at the time of mfg/ production", is this the only difference?

Hello Riki patel,

     PK and MK is the same for the internal module, especially with the same mask set number. If the mask set number is different, you just need to refer to the according errata:

ARM Cortex-M4|Kinetis K20 72 MHz 32-bit USB MCUs|NXP 

    When you create a new project on MCUXpresso, you need to select MK20DX256VLL7.

   The latest mask set for MK20DX256VLL7 is 3N36B

    More details, please refer to this link:

  If you are using 1N36B, just need to take care the 1n36b errata:

Wish it helps you!

Have a great day,
Kerry
