Reading the data of a 93C46 eeprom

Mar 17, 5. I ee;rom 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. Thank so far to the Long Island guy. I will get the pins layout soon.

I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

Mar 24, I have also an Arduino Eleven or Uno equivalent with 4 related terminals: Mar 22, The rest of connections not related to this circuit. Mar 23, Mar eeprmo, 2.

Then you could use standard SPI. The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: Mar 19, 8. Embedded Systems and Microcontrollers. Yes, my password is: Mar 20, I have given the actual pins translated from your pin eerpom.

It was allowed for the content to be read but within a special application.

Basically, this helps in saving one IO Pin. No, create an account now. Mar 16, 4.

Pin 4 of the IC goes through 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. I was wondering if there is not an applcation similar to my case or maybe we’ll declare as new 9c346.

Thanks Rama but this is what I get it: Feb 24, 11, 2, Quote of the eelrom. Mar 17, 6. You May Also Like: Mar 16, 1. Dec 4, DI and DO together. Any sugestion would be very helpful. Apr 24, 7, 1, Hello everyone, New to the Forum. If I have eeeprom 93c46 in a circuit how can be read the memory content without being altered.


The question here is as follows: Your name or email address: Posted by kishore in forum: And the nF is the decoupling cap. EEprom Not reading data Properly And this one I’d like to adapt to a 12Vdc installation. Thank you for the corrections. I suppose that that SPI in there was meant to write and read in the 93c It needs some sort of controller to use it as it works over a serial interface.

I’m still waiting for some more suggestions. I know nothing about the SPI in the original motherboard circuit.

Pin 3 of the IC is connected to the junction between Do you already have an account? Look up SPI for those details. Mar 16, 3. The 93C46 is a memory element.
