Is there a RAM equivalent of the Atmel AT45D081? Or just a good serial RAM on one chip (not someone's parallel ram with a PIC to convert to serial). I have a proto board almost done and would like to add space for external RAM to complement the up to 4 megs of 2 wire (SO and SI combined, CS is SCK through one-shot) SPI FLASH but (get ready for something you have never heard before) I'm low on IO pins and board space. Any ideas very much appreciated. James Newton, webmaster http://get.to/techref jamesnewton@geocities.com 1-619-652-0593 phoneÊ
