Can anyone suggest controller pin to pin compatible to NXP LPC1124?

Hello,

One of our products is using NXP LPC1124 controller. We would like to add some cryptographic features in that product. Controller is running out of memory.

I am looking for a controller compatible (pin to pin) with LPC1124 with minimum footprint of 64KB of flash and 45KB of RAM.

Can anyone suggest the controller?

Thanks a lot!!

There is no pin to pin replacement for LPC1124.

According to your cryptographic features and memory requirement, I suggest you choose LPC551x or LPC552x

Have a great day,
Jun Zhang

Thank you for your prompt reply.

Is there any compatible controller(pin to pin) for NXP LPC1112FHN33_201 with more footprint?

Best Regards,

Arti

No. there is no pin to pin compatible part for LPC11xx

Hi Jennie,

I want to use mbedtls for asymmetric keys generation(using ECC), hashing (SHA256) and signature creation and verification.

Will LPC551x controller fulfill the requirement?

Does it come with mbedtls library? It will be really helpful if you could provide application note or any relevant document.

Really appreciate your help.

Best Regards,

Arti

LPC551x doesn't support mbedtls library

but LPC55S1x does.

Have a great day,
