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 20, Embedded Systems and Microcontrollers.

I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board. I have given the actual pins translated eeprlm your pin nos.

No, create an account now. Mar 22, The problem is still in the interface from 3 control pins to 4 control pins of Eeprmo Eleven. I can not split the pins 3 and 4. Posted by kishore in forum: I will get the pins layout soon. 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 eperom a special application. And this one I’d like to adapt eeprom a 12Vdc installation. Mar 16, 1. Reading the data of a 93C46 eeprom Reply to Thread. Yes, my password is: Do you think should be another approach?

I think it would be helpful for me to find 93×46 simple application using a SPI. Then you could use standard SPI. Mar 16, 2. The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: Basically, this helps in saving one IO Pin.

Your name or email address: Do you already have an account?

Mar 16, 11 0. Feb 24, 11, 2, I eepom also an Arduino Eleven or Uno equivalent with 4 related terminals: Pin 3 of the IC is connected to the junction between I will try to reformulate the case.

Mar 16, 4. Have you tried typing “Arduino SPI” into an interweb search engine? The 93C46 is a memory element. Mar 19, 9. Any sugestion would be very helpful.

93v46 I have a 93c46 in a circuit how can be read the memory content without being altered. 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. Mar 18, 7. The circuit containing the IC should be re-usable as is. DI and DO together. Mar 16, 3.

Look up SPI for those details.

I’m still waiting for some more suggestions. The question here is as follows: Hello everyone, New to the Forum.

Reading the data of a 93C46 eeprom

Either the existing board was designed to allow the contents to be read or it wasn’t. Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that.

Thank so far to the Long Island guy. I suppose that that SPI in there was meant to write and read in the 93c Deprom of the day. Mar 17, 5.
