It needs some sort of controller to use it as it works over a serial interface. Any sugestion would be very helpful. And the nF is the decoupling cap.

Posted by kishore in forum: I’m still waiting for some more suggestions.

Reading the data of a 93C46 eeprom

Do you think should be another approach? Mar 16, 11 0.

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. Do you already have an account?

The problem is still in the interface from 3 control eeprpm to 4 control pins of Arduino Eleven. EEprom Not reading data Properly Thanks Rama but this is what I get it: Thank so far to the Long Island guy. The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: The circuit containing the IC should be re-usable as eerom. Mar 18, 7. I have also an Arduino Eleven or Uno equivalent with 4 related terminals: Thank you for the corrections.

Either the existing board was designed to allow the contents to be read or it wasn’t. I can not split the pins 3 and 4. I know nothing about the SPI eelrom the original motherboard circuit. Quote of the day. For the command streams sent to 93C46 all start, cmd or opcode, addrwhen they are not multiples of 8 bits, then you eeprom pad it up with 0 at the beginning.

The question here is as follows: I will try to reformulate the case.


Mar 17, 6. Deprom this one I’d like to adapt to a 12Vdc installation. Mar 16, 1. I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board. Mar 16, 2. It was allowed for the content to be read but within a special application. I need to identify each of the 8 pins of the other circuit and see what connections need to be done.

Mar 16, 4. No alteration to this circuit.

Pin 4 of the IC goes through Mar 19, 8. 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! I have given the actual pins translated from your pin nos. Mar 22, Mar 16, 3. Mar 17, 5.
