JEDEC standards

Recommended Posts

I don't get it.

What I want to do is design an 8051 system with 2 JEDEC approved 32K EEPROM modules, and a JEDEC approved 8K SRAM.  I want to do it on a single sided board.

It seems that the JEDEC approved standard, just does not work with my 80C51 chip.

Can anyone tell me why the JEDEC standard assigns certain pins to certain addresses and data on the rom instead of having the data pins all on one side of the chip and other pins address?

Membership for JEDEC costs at least $6000 and there is NO way I'm paying $6000 to find out this answer.
