Replacement LPC2132/36

muhammad_rezan — Tue, 13 Nov 2018 08:02:30 GMT

The longevity of LPC2132/36 will be end at 2021.

Is it have other MCU which pin to pin compatible with LPC2132/36?

If no, is it in future NXP planned to produce replacement MCU for LPC2132/36 which pin to pin compatible?

Thanks.

Hi Muhammad,

There is an application note for migrating from LPC2xxx to a LPC17xx devices. You could refer to AN10878 at the following link:

https://www.nxp.com/docs/en/application-note/AN10878.pdf

However, the direct pin-to-pin replacements are for LPC2300/2400. In case of the LPC2132/36, which has up to 512KB Flash and up to 32KB RAM; an option could be considering the LPC5410x MCUs, based on Cortex M4 core at 100MHz (with optional secondary Cortex M0+ core), many peripherals, up to 512KB Flash and up to 104KB RAM, available on LQFP64 package:

LPC541XX|NXP

Hope this will be useful for you.
Best regards!
/Carlos

Hi Carlos,

Thank you for your information.

Unfortunately both are not suitable to direct replace LPC2132/36.

Is it NXP planned to do it in future?
