Mar 16, 2. I have the circuit board with a 93c46 eeprom which eepprom an 8 pin connector is linked to the main board.

I will get the pins layout soon. And this one I’d like to adapt to a 12Vdc installation. 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.

Quote of the day.

The circuit containing the IC should be re-usable as is. The rest of connections not related to this circuit. Reading the data of a 93C46 eeprom Reply to Thread. It was allowed for the content to be read but within a special application. It appears that you are reading mirror pins. If I have a 93c46 in a circuit how can be read the memory content without being altered.


Thanks Rama but this is what I get it: EEprom Not reading data Properly Mar 16, 11 0. 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!

Have you tried typing “Arduino SPI” into an interweb search engine? No alteration to this circuit. Thank so far to the Long Island guy. Mar 23, I will try to reformulate the case. Look up SPI for those details.

Do you think should be another approach? Dec 4, The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven.

I was wondering if there is not an applcation similar to my case or maybe we’ll declare as new descovery.

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 16, 4. Mar 24, I need to identify each of the 8 pins of the other circuit and see what connections need to be done. No, create an account now.


Embedded Systems and Microcontrollers. Pin 4 of the IC goes through Do you already have an account?

Any sugestion would be very helpful. Mar 16, 1.

Your name or email address: Mar 17, 5. Mar 19, 9. Posted by kishore in forum: DI and DO together.

Basically, this helps in saving one IO Pin. Mar 18, 7. Thank you for the reply. Mar 17, 6. Then you could use standard SPI. Also at using an Arduino circuit as well might be a eerom to test but I’ll need more directions for that.

For the command streams sent to 93C46 all start, cmd or opcode, addrwhen they are not multiples of 8 bits, eepfom you can pad it up with 0 at the beginning. Mar 19, 8.

Pin 3 of the IC is connected to the junction between
