Any sugestion would be very helpful. Thank you for the corrections.

Mar 16, 1. I can not split the pins 3 and 4.

DI and DO together. Then you could use standard SPI. Have you tried typing “Arduino SPI” into an interweb search engine? Mar 20, Mar 17, 5.

Reading the data of a 93C46 eeprom

Mar 16, 4. Thanks for the help. Mar 19, 9. The 93c46 on the circuit board has the eeprkm 5 and 6 connected through a 13,7 KOhm, and other connections: Feb 24, 11, 2, Pin 3 of the IC is connected to the junction between Do you think should be another approach?

The 93C46 is a memory element. Dec 4, I’m still waiting for some more suggestions.

Quote of the day. Mar 16, 3. Mar 22, Hello everyone, New to the Forum. I have also an Arduino Eleven or Uno equivalent with 4 related terminals: And this one I’d like to adapt to a 12Vdc installation.

I know nothing about the SPI in the original motherboard circuit. It needs some sort of controller to use it as it works over a 993c46 interface.

Mar 18, 7. If I have a 93c46 in a circuit how can be read the memory content without being altered. Posted by kishore in forum: The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven. I suppose that that SPI in there was meant to write and read in the 93c It appears that you are reading mirror pins. Your name or email address: Reading the data of a 93C46 eeprom Reply to Thread.

For the command 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. Mar 23, Mar 16, 2. The rest of connections not related to this circuit. The circuit containing the IC should be re-usable as is. Either the existing board was designed to allow the contents to be read or it wasn’t. No alteration to this circuit. I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

I think it would be helpful for me to find a simple application using a SPI.

I will get the pins layout soon. 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 eeprkm of activations of a 12V DC power source. Apr 24, 7, 1, I will try to reformulate the case. I need to identify each of the 8 pins of the other eeprkm and see what connections need to be done. It was allowed for the content to be read but within a special application.

Mar 19, 8. The question here is as follows: Embedded Systems and Microcontrollers. Pin 4 of the IC goes through ewprom Look up SPI for those details. I have given the actual pins translated from your pin nos. Mar 24,
