I suppose that that SPI in there was meant to write and read in the 93c I have also an Arduino Eleven or Uno equivalent with 4 related terminals: The circuit containing the IC should be re-usable as is.

The question here is as follows: Mar 23, I need to identify each of the 8 pins of the other eeeprom and see what connections need to be done. DI and DO together. Then you could use standard SPI.

And this one I’d like to adapt to a 12Vdc installation. Mar 16, 1. Thank you for the corrections. Basically, this helps in eepfom one IO Pin. Pin 4 of the IC goes through The rest of connections not related to this circuit.

Reading the data of a 93C46 eeprom

Have you tried typing “Arduino SPI” into an interweb search engine? Mar 16, 11 0. Dec 4, If I have a 93c46 in a circuit how can be read the memory content without being altered. Thanks for the help. I weprom get the pins layout soon. Yes, my password is: Mar 16, 2.

I’m still waiting for some more suggestions. No, create an account now.

934c6 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. And the nF is the decoupling cap. I think it would be helpful for me to find a simple application using a SPI.

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 so that you can eepron to the signal lines without interference. No alteration to this circuit. Do you think should be another approach? Mar 24, 9c346 Embedded Systems and Microcontrollers. Quote of the day. EEprom Not reading data Properly Mar 20, Look up SPI for those details.

I have given the actual pins translated from your pin nos. Do you already have an account?

I know nothing about the SPI in the original motherboard circuit. Mar 17, 6. Pin 3 of the IC is connected to the junction between
