Low Power SDR SDRAM

Low Power SDR SDRAMs (Low Power Single 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.
