93C46 EEPROM for Atari Jaguar cartridge PCBs

If you have to use this you need to use the resistors as in the AN, you need to write a bit bang 93c6 taking care of timing requirements! Mar 22, I have given the actual pins translated from your eeeprom nos. Pin 4 of the IC goes through Do you think should be another approach?

I have also an Arduino Eleven or Uno equivalent with 4 related terminals: The question here is as follows: Your name or email address: Apr 24, 7, 1, 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.


And this one I’d like to adapt to a 12Vdc erprom. Thanks Rama but this is what I get it: The circuit containing the IC should be re-usable as is.

Look up SPI for those details. Mar 16, 2. Mar 18, 7. I need to identify each of eeprlm 8 pins of the other circuit and see what connections need to be done.

You May Also Like: Embedded Systems and Microcontrollers. I can not split the pins 3 and 4. Pin 3 of the IC is connected to the junction between The 93C46 is a memory element. Mar 16, 1. I will get the pins layout soon. Also at using an Arduino circuit as well might be a possibility to test but I’ll need more directions for that. I will try to reformulate the case.

Thanks for the help. Mar 23, It needs some sort of controller to use it as it works over a serial interface. I have the circuit board with a 93c46 eeprom which through an 8 pin connector is linked to the main board. 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.


The 93c46 on the circuit board has the pin 5 and 6 connected through a 13,7 KOhm, and other connections: DI and DO together. Feb 24, 11, 2, Do you already have an account?

Then you could 9c346 standard SPI. Thank so far to the Long Island guy. Thank you for the corrections. It was allowed for the content to be read but within a special application.
