Any news of when PIC18(L)F57K42

[soonc]

Does anyone have any new of when PIC18(L)F57K42 will be available ?

Some limited samples already are.
You need to talk directly to Microchip.
They were showing sample devices at a recent seminar, but these were engineering samples, and may well have a lot of bugs.

CCS won't add support till it is released for a while though.

There is always the increased danger on new devices that you will be the one spending time debugging faults.

I took a glance at the PDF, and aside from x2 memory and x2 RAM what's it got that the 46k22 doesn't?

Just curious as I've used the 46k22 for years and it's 'stable'.

There are several features:

I can eliminate a SOIC-8 and it's crystal, caps etc. with the NCO.... Very important for my work.

Memory is important and 8192 Bytes of SRAM is needed, although I have managed with outboard FRAM it's another SOIC-8 I can dump....

Hardware interrupts are claimed to have "Faster interrupt response time".

That's about it.

The interrupt response times won't happen, till new features are added to the compiler. Initially to get them, you would have to use your own handling.
The NCO is a great feature, but depending on what frequency you actually need, a PWM on a PIC24 might well be able to do this.
Problem is I can see the new features taking a lot of time to actually develop code for.
Honestly there are PIC24's that give all the features but this.
Also if you need 8K of RAM, remember how much will be used already. To get 8K useable, you need a PIC giving at least 10K....

If you are designing a product with a target finish data a year down the train, then it might be worth considering these. However if you only have six months, then think of other solutions. I've used 'leading' chips before, and as a result am a bit cynical....
