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. 93f46 have given the actual pins translated from your pin nos.
93d46 name or email address: The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven. EEprom Not reading data Properly It was allowed for the content to be read but within a special application.
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 get to the signal lines without interference. And this one I’d like to adapt to a 12Vdc installation. I’m still waiting for some more suggestions. Dec 4, Posted by kishore in forum: Then you could use standard SPI.
Apr 24, 7, 1, I suppose that that SPI in there was meant to write and read in the 93c Thank so far to the Long Island guy. Do you think should be another approach?
No alteration to this circuit. Mar 16, 4. Mar 17, 6. I have also an Arduino Eleven or Uno equivalent with 4 related terminals: Basically, this helps in saving one IO Pin. Look up SPI for those details.

The 93C46 is a memory element. Mar 20, Thank you for the reply.
I can not split the pins 3 and 4. Mar 16, 2. Mar 18, 7. The circuit containing the IC should be re-usable as is.

Do you already have an account? You May Also Like: Mar 19, 9. The 93c46 on the circuit reprom has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: If I have a 93c46 in a circuit how can be read the memory content without being altered.
Thank you for the corrections. The rest of connections not related to this circuit. Hello everyone, New to the Forum. Mar 17, 5. It appears that you are reading mirror pins. I will try to reformulate the case. Mar 19, 8. Mar 23, Mar 22, And the nF is the decoupling cap. Thanks Rama but this is what I get it: DI and DO together. The question here is as follows:
