MDT 10F684 16 pin IC

[Abdullah]

Hello everyone
I used Chinese IC MDT 10F684 this is available in 8 pin, 14 pin and 16 pin The 14 pin are same to PIC 16F684 I make any code in positron and upload in MDT IC 10F684 using MDT writer yS pring pro, IC working good but how to add 16 pin IC and make a code in positron 8

First, a manufacture giving all three devices the same part number even though they have different pin counts is idiotic & confusing as it is can be unclear as to which version someone is referring to.

Second, although you seem to have been able to make it work using Positron by finding an equivalent Microchip part, there is no guarantee that would always work, best to stick with Microchip parts to be certain as those are what Positron is written for and tested on.

There are only two ways I can think of...

• Do as you have already done and find an equivalent Microchip part and use that part number (try the parametric search tool), try entering the values for the PIC 16F684 but change the pin count to 16 or
• Copy all the relevant PIC 16F684 files, Rename them as say PIC16F684_16 and modify them to include the mapping for the two additional PortC pins, you should be able to work out from the existing file data how to do that.

However, the first will only work if all the register addresses and their corresponding bits match and the second may require more than simply editing the .PPI and .def files and so neither of those may work.

Yes I agree, using the same part number for a device with more pins than the original 16F684 part is confusing to say the least.

I have only been able to find a Chinese datasheet so couldn't see whether the manufacturer offers software support so I don't know how a customer is supposed to use these devices unless they use the Microchip assembler etc.

I also agree that using genuine Microchip parts would be better until you become an expert. Only then would be the time to experiment with cheap clones.

Do they offer other Microchip PIC device clones?

Yes, the 14-pin MDT IC has no difference; it's fully equivalent to PIC in every way. The main reason for using MDT is the lower price — you get five MDT chips for the price of one PIC. The only issue is the 16-pin version: I don't know how to work with it. It has its own IDE called MDT IDE, but it uses the C language, which I don't know.

I do not think we should be promoting obviously counterfeit products on the forum.

Sorry Sir I'm started this topic for knowledge about defiance between 14 pin and 16 pin not for promoting any platform
