LPC553x MCUs

Seems like some nice parts, mixed signal and direct competition to STM32G4. Opamps, comparators, 16-bit ADCs. Anyone has seen anything or tried the dev board?

Edit: links may help:

They do seem nice, and I think I may get the dev kit some time just to play with it. I was waiting for their release ever since I saw the series listed on the LPC5500 series page. But the LPC55(S)3x product page, data sheets, dev kit and other documentation were made public only 20 days ago (April 1st). I haven't seen any stock of either the micro or the dev kit since, so I would be surprised if anyone has been able to try them yet. I suspect that may take a while.

Incidentally, the thing that I find a bit confusing is how the named the dev board. In the other LPC55(S)xx series they all have names like LPCXpresso55Sxx / LPC55Sxx-EVK. The S means the chip version has the optional security features. Except with the LPX55(S)3x series they somehow ended up naming the kit both LPXpresso55S36 and LPC5536-EVK (non-S). Then there is a "Getting Started with the LPC55S36 Evaluation Board" page that does talk about a LPC55S36-EVK (instead of LPC5536-EVK). I haven't yet found a clear statement in any of the documentation about which micro is actually mounted on the dev kit, the LPC55S36 or LPC5536. Or that they may have two version of the board.

LPC5534JBD64E, LPC5534JBD100E, LPC5536JBD64E and LPC5536JBD100E are available at Farnell.

Just an FYI:

The EVK's are delayed getting distribution due to the Shanghai CV19 lockdown. Some have been trickling through but more are on the way.

It is a very nice part.   I have an EVK and have been playing with the analog features.   

I have been writing some articles on the part:

I was going to do something w/ the EVK and post an article as soon as I get some time.

I just bought 2 OKdo E1 dev board ( LPC55S69JBD100). I have to say that they are very affordable and that was an easy way to get a LPC55. Haven't play with it yet, but I'm really looking forward to the powerquad feature.

I might write some feedback once I get some hours on it.

EDIT: I just realized that the LPC55S6x is another "family" than the LPC553x. Guess I was too focus on the 55… Sorry if I was out-of-context.

Regarding LPC5536, I just received my LPC5536-EVK and I have to say that I'm disappointed with its analog facilities.

Most of all the 16 bit ADC is nothing like 16 bit, see this report here:

Thanks.
