MK20DX256VLH7 alternate

amitghosh — Fri, 17 Apr 2015 05:33:24 GMT

We are currently looking for a drop in replacement for Kenetics series K20D,256KB,64pin part in K22 series processor.

It would be great if somebody suggests us for the same.

Hello Amit,

it is hard to choose alternate for MK20DX256VLH7 in K22 series, because there are differences with frequency and processor.

But if you find only processor, which will meet the conditions for 256KB and 64pin and will be from K22 series,

I have two candidates for you. Just for information you mentioned MK20DX256VLH7 - LQFP 64pin package, 256KB and 72 MHz.

MK22FN256VMP1 - there is MAPBGA 64pin package, 256KB, but different processor and 120MHz

MK22FN256VLH12 - there is LQFP 64pin package, 256KB, but different processor and 120MHz

I hope this helps,

Best Regards,

Iva

Hi Iva,

Thanks for your prompt help.

Both the K22 series processor suggested as replacement are seems to be promising.

It would be great if you could provide comparison for pin mapping/functioning of MK20DX256VLH7 with MK22FN256VLH12.

Regards,

Amit

Hello Amit,

I'm sorry for the delay, I was out of office.

I attached you the pinouts comparison for MK20DX256VLH7 and MK20DX256VLH7.

I hope it helps you,

Best Regards,

Iva
