Just ordered some free samples from Microchip , did anybody has ever gave a try to PIC32MZ2048 family ?
Took 2 of these : http://www.microchip.com/wwwproducts/en/PIC32MZ2048EFH064
Features Sounds huge even if package TQFP and price sounds low (-9€/pc)

I use these at work for testing, they’re nice enough chips. I’ve been meaning to use some for home projects for a while now, but haven’t gotten around to it yet.

Ok nice . I will give it a try for a new core/aout concepts, as well as i am going to receive some free samples of microcontrollers and D/A converters.

 : I am also looking for newer replacement for 74HC165/74HC595 digital shift registers, eg something adapted to the PIC32 Bus bandwith / speed. Maybe some additionnal DMA memory chips too ?
Maybe you have something to advice me or maybe a start point for some researchs ?

Nope, we’ve always used the 144 pin parts, so we’ve never had a problem with the amount of I/O.

 Ok thanks . Now i’ve ordered the 64 pins version i think i will try to stick to it . I was thinking about “simple” high speed digital mux/ demux if you may advice me something ?
What about aditionnal external memory ? Maybe sticking to 144 pins version?
Thanks again for your answers :slight_smile:

I’m afraid I can’t really help much more - I use the board as a reference platform for developing our in-house RTOS and hypervisor products. We have been considering getting some boards made up with CellularRAM attached to the external RAM interface. These are basically DRAM+controller, packaged to behave like SRAM.

thank you  for everything,that’s already a lot =)
I also have to make searchs by my side !
