I would recommend you using 4x 512kbyte devices. There is a big competition in this size and digikey lists a 70ns Toshiba part for $4.13, which together with the required PCB space and assembly costs make a good price. Good advice. Low chip count and size is a good thing but a savings of 80% is definitely worthwhile. Thanks, Craig Steiner |
