@alex_m1

i'm curious - what is their die size, and at what process are they made ?


Our die size will certainly vary based on the different chips we make, but we use both bonding wires and flip chip so the die size will be a fraction of the package size.   The chip used in the LED badge was made on 180µm.

 

And is there any chance we'll see silegon doing microcontrollers

The future is as much a mystery to you as it is to me.  There are a lot of companies doing really well in the microcontroller business, so we will most likely stick with our CMICs; however, tomorrow could bring anything!


Merry Christmas Alex

@Alex: ...with regards to the silegon GPAK, i'm curious...

Hi Alex -- I'll ask them to answer  your questions

Max ,with regards to the silegon GPAK, i'm curious - what is their die size, and at what process are they made ? And is there any chance we'll see silegon doing microcontrollers (some would guess they are not far from low end chinese mcu's in price and manufacturing  - but those lack support, distribution , only sell at huge volumes, etc) ?

@elizabethsimon

Cypress PSoC are similar in that they have a number of drive levels as options and a big thing is that I/O ports can have diferent drive voltages, the down side is the cheap dev boards all have their I/O ports tied to the same drive voltage. I suppose the answer is a resistor pack.

I am just waiting for my Kickstarter reward from iv-Robotics, First Resistors&Capacitor adapted to Breadboard to arrive and maybe my breadborads will support a few more external components without shorting out.LOL

@Luke

I've worked quite a bit with FPGAs and most of the ones I've worked with have some ability to set the drive levels (both current and slew rate) of the outputs. Not exactly the same as current limit resistors but very helpful in reducing overshoot and ringing.

I looked for information about this on the Lattice ICE40 (a nice low cost chip) but haven't found anything yet. I'm sure someone else on this forum would know if these parts have that feature. I haven't looked at the Cypress PsOC to know if they have that ability either...

@lukeT95001 The output drivers do max out at around 10-20ma, so I don't use resistors when I prototype with LEDs, but its not the best solution in the long term.


Thanks for that bit of advice I like the advances in programmable fabric

Not wishing to blow my own trumpet how far could these chips go to providing a Video timing and display answer in one chip without interrupts.

I have done it in another companies programmable fabric.

@Crusty1 I have no doubt that you can set a logic sequence in the GreenPAK chips that would give the same inputs to outputs as the MC14495, but do the GreenPAK chips have current limiters buit into the I/O pins like the current limit resistors built in to the MC14495 chip?

 

Hi Crusty1,  No, we dont have the 290Ω current limiting resistors onboard, you'd have to add them additionally.  The output drivers do max out at around 10-20ma, so I don't use resistors when I prototype with LEDs, but its not the best solution in the long term.

I've also never heard of cheap programmable fabric with these features...but they might be out there somewhere.  Cheers!

@Luke -- did you see Crusty's question where he asked:

"...do the GreenPAK chips have current limiters built into the I/O pins, like the current limit resistors built in to the MC14495 chip?"

@Luke: ...Hi Max, you got it all correct...

That's always music to my ears -- I'm currently running around my office giving myself "high fives" LOL

@Luke: ...we don't have any cicuitry controlling the rise and fall times of the outputs unfortunately.  And there are no settings to configure the input impedance...

This might be something to think aboout for the next generation -- at least to ask your users if they would find this useful...
