i want to trace ( micro controller no .) who micro controller to use in ckt .
pin no 4 has use - ve supply & pin no 10 has use + ve (5 volt ) supply. total pin count no 14 .
googled more time , but not found .
pl help me .
No number is on the micro controller. Bcoz number is erased on micro controller by manually.
So its resion I want to trace the number . I has Google which Micro controller have pin number 4 - ve & pin number 10 + ve (+5 volt ). But not found .
Ok again, what type of equipment is it used in. Are you sure its a microcontroller ?
Since it has only 14 pins I suggest you try to trace out the rest of the circuit to get a better idea of what it is.

I'm 100% sure its a MCU. Bcoz there are one pin for two function . Its possible only in MCU , not any other analog IC . Its use one inverter control card . I want its residing . Bcoz its production cost very low.
How can you tell the difference? Is this some super secret industrial espionage project? Please tell us what you know, so we don't have to play guessing games.
The real question is whether it is an MCU or a logic chip. I hope the OP addresses that assignment with more information than is given in post #7. I (almost) never give up, but my time is running short.
What you ask is the same as if ask you, what chip is my device. it has 14 pins and p1 and p14 is power and gnd.
You need to be more specific and answer some of the questions as well to give more info.
This is not a 1 million dollar guessing game the we kompeet in.
