Replacement for LPC2378

[vivekpjohn]

Hi,

We are presently using LPC2378 in our custom board/product. While trying to procure the microcontroller recently, it was mentioned "product no longer manufactured". We need to know if any pin to pin compatible chip available for LPC2378. We have come across LPC1778 & 1788, which seems compatible. Please confirm whether LPC1778 or 1788 can be used as a direct replacement for LPC2378 without any hardware/board modification.

Hi,

Thank you for the reply. What about LPC1788? is it compatible with LPC2378? What is the longevity for LPC1788? 

Thank you

Hi

The LPC2378 is pin compatible to LPC1778.

However, please note the longevity of LPC1778 are less than 6 years left. We don’t have other pin to pin replacement longer than 6 years.

For other LPC parts, you can consider LPC546xx, LPC55xx. they are not pin to pin replacement, you need redesign your PCB.

Hope this helps,
