Thanks all for helping me
Well, I'm still trying. It's possible that I'm causing the problem but I'm not sure. ID is not the problem, it's 01 20 on every 29f010 I have.
Sector protection is also disabled on all sectors, so it can't be a problem either.
Tried today a SST 49LF002A with the same PLCC32 socket adapter and it worked right. I know it doesn't prove much since the required pins are not the same but...
Have you checked the PLCC32 adaptor pin-pin continuity? Also, have you checked the programming voltage is ok? Find the pin on the data sheet and measure it when writing.
Hello there,
I am newweb here, and am desperate to know how to short the pin C22 without damagin the programmer!
I appreciate uour help guys!
Thanks!

Yes, continuity checks out good in every pin. Also checked with a scope with the probe tip on eeprom legs, got "good" waveforms in every address and data pins with high side around 4volts. But found that Write Enable pin is left HIGH for some reason, from my understanding it should be low during write, maybe it's part of the problem. Any guesses?
Somebody help me, please with post #854!!!
Hello guys,
I own a TL866CS and for the first time i will need to read and write a ATMEGA its the ATMEGA32A in TQFP-44 package.
What would be the best way to do it? I don't think there is a adapter is there?
Thanks!

You need to convert your TL866CS in A version, and then program your atmega via ICSP connection.
Note that using this method (via ICSP) you can't programm your device in "parallel programming interface" mode, so you can't program all fuse and, if IRC, you need also an external oscillator.
Otherwise you should build an adaper and solder all the needed wires and connect them to the 40 pin programmer zif socket. Atmel...
geeezz...
all because i have the atmega with a input pin in short circuit.
The idea is to copy this one to a brand new.
Nothing complicated...
To convert the tl866 you can use radioman's tool, after that you have to solder the icsp wires and the crystal (don't forget the 22pf condensators) to the atmega and, hopefully the atmega it's not protected, you can dump & write the HEX.
With atmel you have to know the fuses because the values are not present in the main HEX.
I'm trying to program some am29f016b chips. It is the 48 pin tsops, I have it on a 40pin board as the 2 pins on each corner are NC.
I know that people have had success doing this as I seen in done on a foreign forum. Similiar to this picture, not mine.
I try programming it but I keep getting errors like this one. Could anyone shed some light on what could be going wrong
Hi,
one of the external images that you have linked randomly disappear...
BTW it's something that has to do with a console cartridge?
Have you tried to burn the chip itself alone without the dip adapter?

Please give an explanation about this capacitor named above? because I want the program to reach a atmega644pa and so I do not catch on to do. I drip on board ICSP working ATMEGA. I must add this capacitor ??
First i'm very sorry if my english it's not the best.
I'm even don't know very well how atmel works. But i will try to help you...
After you have TL866 "A" version you can do also ICSP programming. Select your device and click in the "set interface" menĂ¹ "ICSP port" option.
After that you can click on the information TAB and you should see the interface schematic. The capacitor that i'm talking should be added in parallel to each pin of the external crystal. 22pf are enough.
You can look at this image to show you what i'm talking about:
click me Do you see in the left the two 22pf capacitors?
IIRC atmel need external oscillator when you use ICSP programming interface
Do you have an icsp port on that board?
If not, you have to desolder the chip from the borard and solder the six icsp wires plus the external osc.
I'm sorry but i can help you more... Maybe without the ext osc you can program the chip the same, but i'm pretty sure you can't set some fuses

I've definitely. please read my post to understand the problem I have:https://www.eevblog.com/forum/blog/eevblog-411-minipro-tl866-universal-programmer-review/msg868933/#msg868933
So you have reading problem with ICSP port of your TL866?
This
comment can help you?
I'm sorry, but i have any other ideas...
I don't think it's a system problem, i think the problem it's in the TL866. Can you test the icsp programming with other devices like PIC mcu?

Thank you anyway for more trouble you did to help me. and I believe that the problem have only ICSP connection. while various EEPROM in the basement of tl866 I programmed several times and everything is ok. the right to say more necessary for my work I MCU programming, anyway, will owe to buy any other programmer.
Hi,
Wondering if I may need to convert to TL866A
I am trying to ID a PLCC44 chip that has had the top numbers burnished off by the manufacturer!
I am guessing it's an Atmel MCU, AT89C51 or the likes, but so far the TL866CS cannot deal with the Chip ID box checked during READ. Any help would be greatly appreciated. the chip was getting a Firmware update in-circuit, it went through the routine, and gave a checksum error at the end! I do have another chip I could capture the code off of, if I could correctly ID this.
Thanks in advance!
Made a little headway... I can read the device using Philips/Intel/NXP device 87C52 (C54) (C58). If I save it to a HEX file, and then try to program the device I get an error (can't write it).
The Atmel parts listed are only AT prefixed, and the Atmel 87C52 series start with T. Not sure why those are not listed. I'm still betting it's an Atmel device by the looks of the Lot code / Date code that is still on the IC, compared to what I see in Google search images of Atmel PLCC44 devices. Pretty sure this is not an OTP part, since there is a rs232 port and programming switch on the chassis.
but... maybe it is a OTP part. Those are a much cheaper solution for the Mfg'r, but they screwed the end user if they made that decision before they shipped this product.
Will find out soon enough.
Anyone know why Atmel series AT89Cxx are not listed? Philips, Intel, SST, seem to have equivalent series listed.
Thanks in advance!
