The question here is as follows: It appears that you are reading mirror pins.

Mar 19, 9. I know nothing about the SPI in the original motherboard circuit. Embedded Systems and Microcontrollers.

It was allowed for the content to be read but within a special application. The circuit containing the IC should be re-usable as is. Feb 24, 11, 2, Mar 24, I think it would be helpful for me to find a simple application using a SPI.

Thank you for the reply. 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. The 93C46 is a memory element. 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! Mar 16, 1. Do you think should be another approach?

It needs some sort of controller to use it as it works over a serial interface. DI and DO together. Thanks for the help. Basically, this helps in saving one IO Pin. If I have a 93c46 in a circuit how can be read the memory content without being altered.

Dec 4, I have given the actual pins translated from your pin nos. Mar 17, 5.


I suppose that that SPI in there was meant to write and read in the 93c 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 23, No alteration to this circuit. Any sugestion would be very helpful. You May Also Like: I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

I will try to reformulate the case. Your name or email address: No, create an account now.
