Mar 16, 4. No, create an account now. Mar 24, You May Also Like: Look up SPI for those details. Basically, this helps in saving one IO Pin. It was 93cc46 for the content to be read but within a special application. I can not split the pins 3 and 4. Any sugestion would be very helpful. I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board.

Thanks for the help. I have given the actual pins translated from your pin nos.

It needs some sort of controller to use it 93c64 it works over a serial interface. Mar 19, 9. I will get the pins layout soon. Mar 17, 6. Thank you for the reply.


The circuit containing the IC should be re-usable 93f46 is. I suppose that that SPI in there was meant to write and read in the 93c 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. Thank you for the corrections.

93C46 EEPROM for Atari Jaguar cartridge PCBs

Do you think should be another approach? Mar 23, Thanks Rama but this is what I get it: I will try to reformulate the case. 933c46 need to identify each of the 8 pins of the other circuit and see what connections need to be done. Reading the data of a 93C46 eeprom Reply to Thread.

No alteration to this circuit. Thank eepro far to the Long Island guy. 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.


If I have a 93c46 in a circuit how can be read the memory content without being altered. The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven. Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that. And this one I’d like to adapt to a 12Vdc installation.

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

Yes, eeproom password is: Embedded Systems and Microcontrollers. Have you tried typing “Arduino SPI” into an interweb search engine? The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: Mar 22, The question here is as follows: Mar 16, 2.

Either the existing board was designed to allow the contents to be read or it wasn’t. And the nF is the decoupling cap.
