Low Power DDR SDRAM
Low Power DDR SDRAMs (Low Power Double Data Rate SDRAMs) are memories with 1.8/1.8 V power supply, designed with specific features to reduce power consumption.
All ICs are RoHS compliant.
* Status: P - mass production, S - samples, UD - under development, N - not recommended for new design.
