93C46 EEPROM for Atari Jaguar cartridge PCBs

I’m still waiting for some more suggestions. The question here is as follows: I have also an Arduino Eleven or Uno equivalent with 4 related terminals: Embedded Systems and Microcontrollers.

Thank so far to the Long Island guy. Do you think should be another approach?

Hello everyone, New to the Forum. And the nF is the decoupling cap. Have you tried typing “Arduino SPI” into an interweb search engine? The 93C46 is a memory eepdom. I know nothing about the SPI in the original motherboard circuit. Mar 16, 1. Either the existing board was designed to allow the contents to be read or it wasn’t.

Then you could use standard SPI. 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.

Apr 24, 7, 1, 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!

No, create an account now.

I will try to reformulate the case. Thank you for the reply. The problem is still in the interface from 3 control pins to 4 control pins of Arduino Eleven. I suppose that that SPI in there was meant to write and read in the 934c6 No alteration to this circuit. I have given the actual pins translated from your pin nos.

Basically, this helps in saving one IO Pin. I think it would be eepro, for me to find a simple application using a SPI. Mar 17, 6. Any sugestion would be very helpful.

Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that. It needs some sort of controller to use it as it works over a serial interface.

DI and DO together. 933c46 circuit containing the IC should be re-usable as is.

I will get the pins layout soon. Mar 20, If I have a 93c46 in a circuit how can be read the memory content without being 93d46. Posted by kishore in forum: It appears that you are reading mirror pins. Mar 16, 3. Pin 3 of the IC is connected to the junction between Mar 19, 9.
