The LPDDR2 SDRAMs released today provide reliable drop-in, pin-to-pin compatible replacements for a number of similar solutions in ultra-low-voltage cores and I/O power supplies for mobile devices such as smartphones and tablets.

For these products, the ICs feature auto temperature-compensated self-refresh (TCSR) to minimize power consumption at lower ambient temperatures. In addition, their partial-array self-refresh (PASR) feature reduces power by only refreshing critical data, while a deep power down (DPD) mode provides an ultra-low power state when data retention isn't required.

Featuring a double data rate four-bit prefetch architecture, the LPDDR2 SDRAMs deliver high-speed operation with clock rates of 400MHz and 533MHz, and are available in commercial (-30°C to +85°C) and industrial (-40°C to +85°C) temperature ranges.

The devices offer programmable read or write burst lengths of 4, 8, or 16; an auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto- or self-refresh. The RoHS-compliant ICs are lead (Pb)- and halogen-free.
