Mar 24, Thank you for the corrections. The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven.

Do you think should be another approach? Mar 22, Mar 18, 7. I’m still waiting for some more suggestions. I have the circuit board with a 93c46 eeprom which through an 8 pin eperom is linked to the main board.
Mar 16, 11 0. Basically, this helps in saving one IO Pin. Dec 4, For the command eepprom sent to 93C46 all start, cmd or opcode, addrwhen they are not multiples of 8 bits, then you can pad it up with 0 at the beginning.
Apr 24, 7, 1, And the nF is the decoupling cap. I think it would be helpful for me to find a simple application using a SPI. I have given the actual pins translated from 93c4 pin nos.
Your name or email address: Mar 16, 3. I was wondering if there is not an applcation similar to my case or maybe we’ll declare as new descovery.
The rest of connections not related to this circuit. DI and DO together.
Pin 4 of the IC goes through The question here is as follows: I will try to reformulate the case. Mar 16, 2. If I have a 93c46 in a circuit how can be read the memory content without being altered. It appears that you are reading mirror pins. The circuit containing the IC should be re-usable as is.
Thanks Rama but this is what I get it: No, create an account now. Mar 17, 6. You May Also Like: Reading the data of a 93C46 eeprom Reply to Thread.
I know nothing about the SPI in the original motherboard circuit. Thank so far to the Long Island guy. Feb 24, 11, 2, Mar 16, 1. And this one I’d like to adapt to a 12Vdc installation. I need to identify each of the 8 pins of the other circuit and see what connections need to be done. Either the existing board was designed to allow the contents to be read or it wasn’t. Do you already have an account? Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that.
Quote of the day.

Mar 17, 5. Hello everyone, New to the Forum. Thank you for the reply. Mar 20, Mar 16, 4.
EEprom Not reading data Properly If you have to use this you need to use the resistors as in the AN, you need to write a bit bang SPI taking care of timing requirements! It was allowed for the content to be read but within a special application.

I can not split the pins 3 and 4. I have also an Arduino Eleven or Uno equivalent with 4 related terminals: It needs some sort of controller to use it as it works over a serial interface. If not then more drastic measures will be required including a “vampire” connector that taps into the existing circuitry or desoldering and isolating the chip deprom that you can get to the signal lines without interference.
