@ NorthGuy
It also makes sense in terms of inter-core communication that can be much faster and easier than with separate µCs.

Could be an Arm dual 32bit core in there handling the 16bit pic interface.
They have experience in multicore chip designs.
 
Would a Pickit 4 be needed?

A bit speculative: most likely we'll need the '4s for this new type of device. If we're very lucky, the '3s will be updated 😎

Yes, but you make more money if it doesn't work on the 3's.
 
I'll see what Dave from EEVBlog say on it is.
 
I found find this interesting.  Jack Ganssle.

Embedded world is here.
They already announced the PICKIT4 and the new Linux Modules..
 
What about the new dspics? any news?

Should be interesting with 1 core to handle interrupts.
 
10mm x 10mm x 1mm
That's a tiny chip.

At mouser, it has the datasheet, https://www.mouser.tw/dat..._dsPIC33CH-1371137.pdf

Interesting... old style-datasheet by the way :) better like this, I believe.
 
The Master-Slave interface looks good.
I was also taking a look at what is exactly "CAN FD"

Looks like the dsPIC33CH is the dual-core version of the dsPIC33CK, minus a couple of 5VT pins
and both seems to be pin-to-pin compatible with the dspic33EV, minus the voltage levels
 
**33CH has 2 timers 12 ccps instead of 1/9. even better. 4 ADCs/DACs instead of 3. 8 DMA (6+2) instead of 4.
if mouser pricing is correct, it's also incredibly cheap at 4.81 euro in singles
aw yes :)
 
let's just hope that the first errata doesn't contain
"CPU: Slave core is not functional" or something like that

It has some instructions that are not fully documentated.
Need DSC Programmer’s Reference Manual” (DS70000157)
 
DIV2 preserves w1:w0, maybe the results go on the stack.
FLIM instruction?
MAX instruction?
BREAK instruction? stop code execution, looks like it stops it dead.
 
LDSLV - I can see that instruction as useful.
VFSLV - and that.
LAC.D and SAC.D - new.
new bitfield instructions.
 
There should have been more flash memory since cpuM has to store the program/s for cpuS.
I think with an sd-card it would be possible to load code and send it on to cpuS.
 
Better than their new single core CK.
 
I want one for xmas.

What I would do with this litle beauty?
It's coming a bit late - I'm currently developing a SENT to (dual channel) analog converter based on a PIC16F17xx (dual 10-Bit DACs).
This one with HW SENT interface and 12-Bit DACs would have come handy - exempt for the 3.3 V supply. (I need 0..5 V analog outputs).
Now I have to go with a software SENT decoder on an 8-Bit core. Not impossible, but a bit of a nuisance.

If SENT to DAC only it should be no problem with PIC18 or even 16.. maybe you can miss a packet every few of them.. as you said, just a little nuisance..
 
why not dsPIC33EVxxxGM002? and use the high speed PWM as a DAC...
I wonder, are you converting a SENT sensor to an analog one to interface with older equipment?
 
I used the 33EV series for my SENT related tasks, then i went on and wrote my software emulation for the protocol (which, funnily, is currently running also on the 33EV, i'm not using the sent anymore...)
for 3V3 MCUs it was no issue, just use a 5VT pin, with the input filtering network as suggested in the standard. for the output, a logic level FET or a 5VT output pin configured as open drain, either one followed by the output network suggested in the standard...
