    Chip identification

    Hello everyone.

    I picked up a cheap kitchen liquidiser at the local flea market which perhaps unsurprisingly doesn't work. It has a remarkably sparse control board with one SOP 20 controller in the middle, which I cannot find any info on.

    If I'm not mistaken the number is TG49141AX07 with ATL1000 and 01 12 19 (date?).


    Any ideas as to where a datasheet might be found?


    Thanks in advance

      Have you measured anything? Can you tell us the Vcc voltage? (between pins #20 and #10 ?)

      Does this appliance have a transformerless power suply?

          I haven't measured any voltages but yes, it has a transformerless power supply.

          The next thread was actually going to cover this

              Common SPI bios chip programming Questions and Answers
              ----------------------------------------------------------

              Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

              A: If you can`t read from it how do you expect to write to it ?.

              Q: Why is my bios chip unreadable ?.

              A: The programmer is faulty or has a worn or broken zif socket.

              The USB cable is frayed,connector pins worn or some other physical damage.

              Not enough amperage or voltage to power the programmer properly.

              Asus Chromebox CN62 - wrong chip put on BIOS reader
              by BMCappelletti
              Long story short:
              - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
              - gave the computer to his son a couple years later
              - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
              - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
              (seems like the story was not that short)

              He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

              Help EZP2023+ updated chip database for w25q256jveq?
              by Troystain
              Hello, anyone here have updated ezp2023+ chip database in .dat file format.

              I need to add w25q256jveq chip but I do not know what data should I type.

              I'm using the ezp chip dabase editor posted from here https://www.badcaps.net/forum/troubl...ro-programmers

              The currenty unit model that I am trying to detect is HP elitebook 640 g9 which is currently locked on admin bios....

              Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
              by acedogblast
              This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

              There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

              2012 Mac SSD (SanDisc Wide One) burnt chip identification
              by abajor
              I have an SSD from a 2012 to early 2013 Macbook pro, the SanDisk model SD5SL2-512G-120SE

              Attached is a photo of the burnt chip. I'm assuming it's some sort of voltage regulation chip. The numbers are obscured by the damage.
              I am attempting to recover data from this SSD, obviously this chip needs to be replaced before anything can be done.

              Is there anything else I should check to verify the health of the NAND?
              Thanks if anybody knows what part I'm looking for....
