LPC1769 EOL?

danielholala — Thu, 04 Mar 2021 09:07:37 GMT

Hi,

the availability of LPC1769 is really bad at the moment. Mouser and Digikey have discontinued the part that I bought so far (LPC1769FBD100,551), Farnell even states that the device is no longer manufactured:

Mouser states that there's a replacement but it has a lead time of 52 weeks:

What is correct and what is the current production status of this device at NXP?

Thanks.

according to this

https://www.nxp.com/products/product-information/product-longevity:PRDCT_LONGEVITY_HM

lpc1769fbd100 has a longevity of 15 years from launch in December 2009...

I also did not expect its EOL until 2024, however, I think that a device not being available for a year is close to being EOL. At least this shortage of supply is very unexpected and motivates me to replace this processor on existing designs sooner rather than later.

You might want approach NXP or an official distributor directly, to get clarification.

Normally, silicon vendors are messaging their clients about impending EOL events and possible last-buy options. I am (i.e. my company) in the middle of one, for a MCU from the mid-90s. Quantities per type are in the 4-digit range, so not really huge.

Hello

The LPC1769 is not EOL, this part is in the longevity program so the part will not be EOL until the program ends.

If you have more questions do not hesitate to ask me.
Best regards,
Omar

@Omar_Anguiano Omar, thanks, can you please confirm that we calculated correctly and that the longevity program of LPC1769 will run until end of 2024?

What is the difference between LPC1769FBD100,551 and LPC1769FBD100K? The product data sheet is silent about the "K" part number.

Hello

You are correct, the LPC1769 will be at the longevity program until the end of 2024.
The difference between LPC1769FBD100,551 and LPC1769FBD100K is the packing.

Let me know if this answers your questions, if you have more questions do not hesitate to ask me.
Best regards,
Omar

Dear @Omar_Anguiano ,

I'm so glad that I ordered my share of LPC1769 devices end of January. Now about a month later, this device is not available any more. I do not dare to imagine what would have happened if I hadn't place my order then. It was sheer luck.

This device is not EOL as you confirmed, nevertheless, the lead time of 52 weeks is unexpected to me.

Is this usual to expect that NXP devices get out-of-stock for a whole year?

Can I count on NXP to make the device available in about a year again?

Thanks.
Dan

Your question about availability is understandable, given the overall industrial situation with supply of semiconductors. There are many analysis articles posted in many of the specialized publications about this, they are giving a good background about the initial trigger and dynamics that happened to our industry within the last year.

However, please understand that we will not discuss this in more detail here in the forum.
I apologize for not being able to answer your last questions.
Best regards,
Omar

Thanks, @Omar_Anguiano , for responding.

You write:

If not here in the forum, where can I get the answers to my questions?

As a customer to NXP products (albeit in relative low quantities) I think these a valid questions that deserve an answer. Especially, as other and more recent controllers from NXP (i.e., LPC552*) also have low availability. Going forward, I learned not to choose the controller based on technical features only but also on availability. Further, choosing the package might make a big difference in availability (i.e., move from HLQFP to VFBGA for better availability). I think to make the right decisions this needs to be discussed with someone with expert knowledge from NXP.

Cheers,
Dan

Distributers cannot get these parts either.

The situation is extremely bad.

You are correct, the LPC1769 will be at the longevity program until the end of 2024.

Hello @Omar_Anguiano ,

fast forward four years, it's now 2025 and LPC1769 has dropped out of longevity program according to product longevity page.

On the product page, it says the part is still "active". How long will NXP keep the LPC1769FBD100 available?

Thanks.
Daniel
