EMIF device speed
The rated EMIF speed, referring to both EMIFA and EMIFB, of these devices only applies to the SDRAM
interface when in a system that meets the following requirements:
− 1 chip-enable (CE) space (maximum of 2 chips) of SDRAM connected to EMIF
− up to 1 CE space of buffers connected to EMIF
− EMIF trace lengths between 1 and 3 inches
− 166-MHz SDRAM for 133-MHz operation (applies only to EMIFA)
− 143-MHz SDRAM for 100-MHz operation
