I was wondering if there is not an applcation similar to my eeeprom or maybe we’ll declare as new descovery. And the nF is the decoupling cap.

Reading the data of a 93C46 eeprom

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. Any sugestion would be very helpful. Mar 19, 8. Reading the data of a 93C46 eeprom Reply to Thread.

Thank you for the reply. And this one I’d like to adapt to a 12Vdc installation. Thanks for the help.


I suppose that that SPI in there was meant to write and read in the 93c I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board. Mar 22, The rest of connections not related to this circuit. Do you already have an account? Do you think should be another approach? I need to identify each of the 8 pins of the other circuit and see what connections need to be done. I can not split the pins 3 and 4.

93C46 – x8(1k) Serial CMOS EEPROM Technical Data

Mar 24, Pin 3 of the IC is connected to the junction between eeporm Posted by kishore in forum: Mar 16, 4. Mar 17, 6. I will try to reformulate the case. 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!

93c46 Eeprom Writing/reading Help

Basically, this helps in saving one IO Pin. Quote of the day. Apr 24, 7, 1, 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.


Embedded Systems and Microcontrollers. It appears that you are reading mirror pins.

The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: It was allowed for the content to be read but within a special application. Thanks Rama but this is what I get 93c446 I think it would be helpful for me to find a simple application using a SPI.

93C46 EEPROM for Atari Jaguar cartridge PCBs

Hello everyone, New to the Forum. I will get the pins layout soon. Also at using an Eepfom circuit as well might be a possibility to test but I’ll need more directions for that.
