Unless I'm missing something, you're missing something.


If you expand your searching to include up to qfn20 and probably even qfn24, you can have the footprint of a dip14 with 0.3" width pin spacing (assuming you only use up to 14pins).

I paid under $30 total for 100 of these boards from jlcpcb (plus 10 of another board about 4 times the size). Its only a good deal if I use use many of them, but it shows you can make your own adapter board, or skip the adapter phase, once you settle on something. To get to that point, you get a $10 dev board and see what you can do, and if it works out you can go to the next step, or if not, get another dev board and try again.

Ur right.  I claim to suffer from ADC DAC dyslexia. 

[cv007]

I have the same thing, but currently its limited to when I'm typing on the keyboard (in addition to normal typing problems). I'm losing finger sync, I guess.

...but their flagship is the MSP430G2553 in DIP 20 pins.

Cut the last 6 pins and keep them floating

I have made my projects with the Bluepill because it is a moderately powered 32-bit ARM processor in a DIP-40 package, so it can be mounted using pin header sockets into a PCB or a breadboard.  Not as small as you want, but cheap and readily available.

Hello, what chip is 40pin DIP ARM ?

Hello, what chip is 40pin DIP ARM ?

You got your 2.54mm pitch on 15.2mm centers. That will fit directly into any 40-pin DIP socket you can find. Just solder machine pin headers on it and close your eyes and pretend.

It's not a 40pin DIP package, it's an STM32F103C8 mounted on a small PCB with pins so it can be used on a breadboard (or DIP socket).   They are very cheap to buy, though it seems there are plenty of them using STM32 clones rather than genuine parts. Bluepill details.

Anyways the ports on other chips are different.
PORTC has 6 pins on other locations.

Yes. Because chips *are* different. If you want to use Port named "C", with same pins as PIC16F1704, then use (surprize!) PIC16F1704.

There are actually quite a number of Texas Instruments MSP430 series microcontrollers available in PDIP14 package here is a list with some PIC thrown in there too.

Happy reading.

Please read subject of this thread carefully. It says "faster". Unfortunately mentioned MSP430 mcu's are slower, 16MHz max.

Huh?!? I mentioned MSP430G series above as well. The original post mentions a 8MIPS 8bit microcontroller, thus a 16MIPS one is surely faster in most (if not all) scenarios.

PIC enhanced mid-range cores take 4 clocks per instruction cycle. The MSP430 I've looked at lately take 1 clock per instruction cycle.

Oh, Right. PIC is not RISC 1-cycle/instruction MCU, I forgot that. At 32MHz it is slower than 16MHz msp430. Anyway I do not agree suggesting just 2x faster MCU when it is not known - it will be enough for the task or not. Better learn some ARM chip where you have virtually unlimited performance upgrade path, if we ignore PDIP14 requirement for a moment. I doubt OP will live in the "DIP through-hole camp" for a long time..

I also still have windows XP.
If i stop DIP they will go broke.
Save DIP by buying.

[NorthGuy]

Measuring performance in MHz is not very good idea. What's important is what the MCU can do in the alloted time. This certainly depends on the clock speed, but this also depends on the instruction set and on what you're doing and how you do it.

Houston, we have a problem

[schmitt trigger]

Windows XP?

But....why?

[jhpadjustable]

Does anyone else feel a sudden urge to upgrade their home lab's capabilities to BGA/WLCSP levels?

[cv007]

Since there are no numbers attached to 'faster', maybe all you need is 'a little faster'. You can probably do a little overclocking to get a little faster. Not sure how the pll will feel about something >8MHz coming in, but it would probably be worth the 10 minutes to play around. You can start by going all the way- 16MHz internal w/pll 4x, then work your way down which then requires an external clock or crystal. Maybe 12MHz (Fosc/4) vs 8MHz is 'faster' enough. Maybe the pic does not like any of it. Easy enough to find out. (I have tested this on a newer/similar pic16f, but I don't remember what the result was)

If this was something important, then you don't have to even consider doing something like that, and there are plenty of other mcu's that can do the job 'faster'. But if not so important, why not.

[Jan Audio]

No i "upgraded" my DSPIC also with max finetuning, wouldnt reccomend, getting weird noises on the audio, dont know why.

It would be a nice non-solderable winter-upgrade for my new project if there was a faster PIC16 port & pin compatible.
Asking for stuff that dont exists is my normal behaviour.

Winter is to cold to solder, winter is programming time.

[NorthGuy]

Winter is to cold to solder ...

Soldering is warm, even hot

OK I am going to stand by my original recommendation to look through the MSP430 product set in PDIP-14.  I think it more than stacks up against the PIC-16 in that same package form factor that you are using now.

MSP430G2231IN14    62 nanosecond instruction cycle
PIC161704               125 nsec instruction cycle

From the datasheets.   Sure looks like the MSP430 part is a “faster DIP14” chip to me.  2X faster, since it takes half as long to execute an Instruction. Cycle time is what matters not clock speed. That and instruction width:  the MSP-430 is a 16-bit processor, your current Pic “16” is an 8-bit processor.

Not that speed is everything there is also the development stack, the depth of the user community, depth of technical  support by the manufacturer.  I happen to think TI wins there too, but others may differ.

Hope this helps and if it does, You’re welcome.
