SPI is becoming a darling boot source, it is only 2 wires, and the ROMs are physically much smaller, but are similar densities to PLCCs. SPIs right now are mostly SO-8s, and socketing SO-8s is an expensive thing to do (much more expensive than a PLCC socket). The SPI ROMs themselves, however, are cheaper than their LPC/FWH PLCC counterparts. That is what makes me think SPI will take over soon. Maybe that is wrong, and PLCCs will last 5 more years, who knows. (NAND may also be a near term option on some southbridges)
certainly in embedded soldered-on is attractive.
Our job will get harder, but I think we will have to work it out.
