18F16Q41 supported? Cannot compile a simple prog

[TimB]

Hi all

I'm looking at a device with more ram to replace a 18f13k22.

Adding device 18F16Q41 and Positron studio seems to show it supported. Searching the forum it is mentioned a few times.

I tried a simple

device 18F16Q41

Dim A as Byte

while 1 = 1

Inc A

Wend

But it fails to compile with no reason why and Positron studio has no fuses for it

Any pointers

Thanks

Tim

Ok I saw a thread that they are not supported yet. I will wait or look for another device

Microchip suggest the 18F24Q10 as an alternative (newer) product.

Bonus, there are some available: https://www.findchips.com/search/PIC18F24Q10

Careful with some of the 24q10 parts. We had an issue with some being the first release and had errata issues.  Just try to make sure they are the latest rev.

I looked seriously at the 18F24Q10 but the chip has more pins than I need and my PCB space is limited. I could use the QFP but that is tiny and the next biggest is a pain to hand solder.

So looked at the 18F16Q41 I will keep looking there are a number of new devices that might work like the PIC18F14Q41

Hi Tim,
sorry I should have checked that Microchip's suggested alternative was sensible. It clearly wasn't.

The trouble is that any of the new 18F devices require using a new assembler (PIC-AS), or at least a modification to MPASMX like the folks at Swordfish have done.

The Q10 and Q43 were the last ones that are still supported by the stock version of MPASM v5.87.
The Q84 was supposed to be but that doesn't actually work (and was obviously never tested).

Thanks tumbleweed

Very informative and has solidified my future pic choices.

Appreciated

Thanks also to the other posters
