Basically, this helps in saving one IO Pin.

It needs some sort of controller to use it as it works over a serial interface. You May Also Like: Do you already have an account? Do you think should be another approach?

Feb 24, 11, 2, Thank you for the reply. And this one I’d like to adapt to a 12Vdc installation. Mar 19, 9. The rest of connections not related to this circuit. Mar 23, I’m still waiting for some more suggestions.


And the nF is the decoupling cap. Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that. The 93C46 is a memory element. Thank you for the corrections. The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven. Mar 16, 3.

93C46 EEPROM for Atari Jaguar cartridge PCBs

Mar 16, 1. I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board. Thanks Rama but this is what I get it: I know nothing about the SPI in the original motherboard circuit.

Yes, my password is: Mar 16, 11 0. Mar 16, 4.

93C46 EEPROM for Atari Jaguar cartridge PCBs

I suppose that that SPI in there was meant to write and read in the 93c Look up SPI for those details. Hello everyone, New to the Forum. Thanks for the help. 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. Mar 17, 6. No alteration to this circuit.


Embedded Systems and Microcontrollers. Pin 4 of the IC goes through Mar 18, 7. I eerom get the pins layout soon. Have you tried typing “Arduino SPI” into an interweb search engine?

Reading the data of a 93C46 eeprom

DI and DO together. Mar 20, If I have a 93c46 in a circuit how can be read the memory content without being altered. I have also an Arduino Eleven or Uno equivalent with 4 related terminals:
