Reading the data of a 93C46 eeprom

Posted by kishore in forum: And the nF is the decoupling cap. It needs some sort of controller to use it as it works over a serial interface. Have you tried typing “Arduino SPI” into an interweb eperom engine? I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

93c46 Eeprom Writing/reading Help

Do you already have an account? Look up SPI for those details. Thank you for the reply. Mar 19, 8.


Mar 19, 9. The question here is as follows: EEprom Not reading data Properly For the reprom streams 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.

I have given the actual pins translated from your pin nos. It appears that you are reading mirror pins. Hello everyone, New to the Forum.

9346 have also an Arduino Eleven or Uno equivalent with 4 related terminals: Feb 24, 11, 2, I am looking for a link or a simple application to be used in reading the data of a eeprom type 93C46 circuit used for counting the number and duration of activations of a 12V DC power source.

Basically, this helps in saving one IO Pin.

Mar 16, 11 0. Mar 17, 6. And this one I’d like to adapt to a 12Vdc installation. Either the existing board was designed to allow the contents to be read or it wasn’t. I was wondering if there is not an applcation similar to my case or maybe we’ll declare as new descovery. I will get the pins layout soon.


I’m still waiting for some more suggestions. Reading the data eeeprom a 93C46 eeprom Reply to Thread. It was allowed for the content to be read but within a special application. If I have a 93c46 in a circuit how can be read the memory content without being altered. Any sugestion would be very helpful.

Mar 16, 4. Yes, my password is: Mar 18, 7. Pin 4 of the IC goes through I think it would be helpful for me to find a simple application using a SPI. I will try to reformulate the case. Mar 16, 93f46. I know nothing about the SPI in the original motherboard circuit.
