Digital IC Tester
Thursday, November 20th, 2008An Integrated Circuit tester (IC tester) is used to test Integrated Circuits (ICs). We can easily test any digital IC using this kind of an IC tester. For testing an IC, we need to use different hardware circuits for different ICs; like we need a particular kind of tester for testing a logic gate and another for testing flip flops or shift registers which involves more complication and time involved will also be more. So here’s an IC tester to overcome this problem. Unlike other IC testers, this is more reliable and easier since we don’t need to rig up different kind of circuits for different kind of ICs, each time we need to test them.
Unlike the IC testers available in the market today which are usually expensive, this IC tester is affordable and user-friendly. This IC tester is constructed using 8951 microcontroller along with a keyboard and a display unit. It can test digital ICs having a maximum of 24 pins. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This IC tester can be used to test a wide variety of ICs which includes simple logic gates and also sequential and combinational ICs like flip-flops, counters, shift registers etc. It is portable and easy to use.
The block diagram of the programmable digital IC tester is as shown in below. It consists of two 8951 microcontroller ICs, a 24-pin IC socket, a keyboard unit, a display unit and indicators.
To test a particular digital IC, one needs to insert the IC into the IC socket and enter the IC number using the keyboard and then press the “ENTER” key. The IC number gets displayed in the 7-segment display unit.
Four LEDs are provided as indicators. If the IC being tested is a logic gate, then each of the 4 indicator LEDs correspond to the 4 gates of the IC. In any other case wherein the inserted IC is not a logic gate, all the 4 LEDs work as a single indicator.

sir This project is very usefull to me.I want hex code for ur program.
January 9th, 2009 at 6:46 pm
sir,we would like to do digital ic tester as our mini project..but when both the programs are build using keil(simulation software) a lot of errors are seen and was unable to create the hex file.could you please correct the same and mail me.
January 18th, 2009 at 11:37 am
sir i am chethan studying in final year diploma we are doing the project that you have submitted on this website but we are not sure that it will work for every ic’s so can you tell me if it suit for all the ic’s & tell me the total cost required for this project………. please……..
January 20th, 2009 at 2:24 pm
Hi,
@keerthik
Pls let me know where exactly u r getting errors.
@chethan
I have written code to test only few gate Ic’s AND, OR, NOT, NAND
You can write code to test any Digital Ic’s.

hi sir,
i want to do same project but using pic 18f452 and i want to make use of memory card too .
basically i want to use memory card to store tests for all kinds of ICs.and while testing when we hit the number of ic using keypad. i want pic to search for that program in the memory card. if memory card had that program then it should send it to pic and pic will perform function to test ic. and then pic shall b able to display result on LCD.
could you tell me is that possible. i will be thankful to you if you can help me with this

Thanks for posting this! It gave me a clue how to parallel interface microcontrollers. I currently working on the same project but with a PIC micro.
Funny how most of the “graduating” students above dont even have a clue and are basically wanting to be spoon fed the answer.
Do some research and testing boys, that’s what engineers do.
Sorry for the rant.
Again, thanks for the valuable info, Sir!

Good Project……….But what if the IC is not properly configured and what if it does not work before it is being tested.
An IC tester should be that whether it is in a working condition or not is also has to be tested …….prior to knowing that it is a particular IV like a NAND,NOR gate etc

Hi,
I think,
1)setb a.0 is wrong instruction,Instd of tht u can use=>
mov a,#01h..
2)LED disply will show only 2 digits,like 04/32/86..Then y 5 seven segmentLED are used?
Also for 4LED’s u could hav used remaining pins of P3 port of master IC with the help of some minor changes in code..
Comment/reply expected asap..

hi all,
I am an civil engineer and having a keen interest in electronics. my daughter is in Final year BE(IC) and she has selected this project (Digital Ic Tester) for her final year presentation. We have decided to build this project at own. we have finished the circuitery part as well as 89c51 programming. But the project is not upto the mark.we r in confuse ,wether it has hardware error or programming error. when i give 5 volt to circuit ,some 7-seg start to blink.but not keypad operation succed.i used wellon ic programmer. but it only accept .obj or .hax file.and our code is in assaambly. i had tried lot off software available on net. but no results. it gives lot off error like illegal oerand error,etc. will any one give me the .hax file. otherwise all our works will be in dustbin. I have knowledge of c and vb, but not femilier with assambly language.can anyone help.It is alredy passed the due date for her presentation.but no result.my email is vu3jpd@yahoo.com
May 10th, 2010 at 1:39 pm
I have corrected the code but hardware does not working. It seems it require more component in circuit or design is incomplete. It is vsry sad to inform that we have selected this project for final year.all the documentaion is alraedy prepared but hardware does not work after many many consultation till today. And my daughter is going to submitte her project which is not working. It is vary sad that i have trust on this site and choose the project but it does not working. Code itself has very much error and hardware design is also incomlete. I have realy very much ashame that i have select this project from this site and played with the carreer of my daughter.
May 19th, 2010 at 2:28 am
sir
i like this idea and would like to implement it as my final year project.
i would be grateful if u can provide me following things..
1]Complete description on how we can interface keyboard and indicator to the 8951 microcontroller
2] Is this keyboard different from the keyboard of computer, if yes How can I design it?
3]You have said that this digital IC tester is used to test any ICs and to test a particular digital IC, one needs to insert the IC into the IC socket and enter the IC number using the keyboard and then press the “ENTER” key. The IC number gets displayed in the 7-segment display unit.Here, what part of the IC is tested?
4]detailed circuit diagram and details abt the project.
5]PCB layout of the project.
6]how it tests the IC that is how it checks the IC.what is the logic ?
7]why to use 2 microcontrollers?
also if u have any links or other material which supports this poject .
thanking you in advance..!!
May 20th, 2010 at 4:48 pm
Hello,
Integrated circuits can fail because of internal shorts. I have seen chips smoke, explode, and melt plastic breadboards. I see that you do not protect the 8951 chips from high currents. Is this not necessary?
Thanks

I think Bigfoot is blurry, that’s the problem. It’s not the photographer’s fault. Bigfoot is blurry, and that’s extra scary to me. There’s a large, out-of-focus monster roaming the countryside. Run, he’s fuzzy, get out of here.

Hi Ranjith
I would be very interested to know what assembler you use to compile the code give on pages 3 & 4.
After trying your code in Metalinks ASM51 assembler I find it impossible to build an Intel HEX file from the data you supplied.
I know from reading your blogg that you are not a very good responder to commenters queries! Therefore I will respond with the reasons why the code you give will not compile.
