    ATMEGA324P Eeprom reading

    Hi,

    I need to ask for help.
    I have an Atmel ATMEG324PA LCD controller.
    I want to read the contents of this into a .rom file.
    What kind of eprom reader would be good for it?
    I could borrow a Pickit v3 and a RT809F reader with PEB-1 from a friend of mine.
    Are these good for it? Unfortunately, I did not find an exact compatibility list for any of the readers.
    Does anyone have experience with this?

    Thanks in advance for the reply

      software should be AVRdude
      https://www.nongnu.org/avrdude/

      hardware, you can use a lot but i like USBasp - only $2 on ebay

      but only if the chip has not had its security bits set.

          T480 trouble reading thunderbolt eeprom - tips?
          by surprisedHacker
          Hi,

          I have a T480 which suffered a failed bios update. I can reliably read and flash the WInbond 25Q128 (U49) but it's still dead (no post, just musical beeps). Turned to the Thunderbolt eeprom (25Q80 in U15) but I can't read the same data from it twice in a row - it's different every time. I'm using a CH341G (same as on https://www.onetransistor.eu/2017/08...schematic.html) in exactly the same way, just moving the SOIC clip from one to the other (noting location of pin 1). Both are 3.3V devices.

          The coin cell backup battery is out, the main battery...

          93C46 and 93C56 EEPROM
          by SidneyCanadas
          I tore apart my instrument cluster for my 2008 Toyota Corolla made in 2007 in Cambridge, Ontario, Canada and pcb location: IC6=EEPROM is a surface mounted device with part # of 93C46W7, some claim the EEPROM out of a Camry part # 93C56 will allow odometer to roll over 299 999 KM or miles. The data sheet for both is below:

          https://cdn.badcaps-static.com/pdfs/...c6e42b20d3.pdf 2

          Anyone know if the Camry one will work on my Corolla?. And which EEPROM reader/writers do you all recommend I purchase that will allow me to read the old values of the old...

          Pioneer DEX-P99rs "No EEProm " diagnostic code.
          by dmccul2698
          Hello, My head unit developed strange behaviors so I ran the built-in diagnostic package which returned "No EEProm". The service manual says there is no EEProm connected. I approached Pioneer and they said to swap out the DSP board. All said and good but the DSP board is $860 USD. I am hoping someone can help me

          1). Understand the schematic and check the connections between the EEProm and DSP
          2). Check the functionality of the EEProm

          I don't know if this is the unit's problem but it's a place to start.

          I have little to no electronic experience...

          Programming KBC IT8987VG ASUS TUF FX506L RT809F+PEB
          by araxnido
          Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.

          When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which...
