  • Densities: 4 Gb to 128 Gb - Provides flexibility for a variety of applications
  • Configurations: x16, x32, x64 - Enables fewer components to support wide bus architect.
  • Core Voltages: 0.6 V, 1.1 V - Helps Reduce Power Consumption
  • Temperature Ranges: –40 ˚C to +95 ˚C IT, –40 ˚C to +105 ˚C AT, –40 ˚C to +125 ˚C UT

LPDDR are DRAM devices optimized specifically to address the power consumption issues in battery-operated applications. It was originally developed for handsets and ultra-portables.​

Some of the reasons you would use LPDDR over other options are:

Performance: peak bandwidth 33% faster compared to DDR4

Optimization: x32 configuration offers BOM savings for certain low density applications

Power Consumption: 5 times lower power consumption in standby mode compared to standard DRAM

Space, form factor, weight: MCP (Multi chip package) and PoP (package-on-package) designs save PCB Space

Configurations: x32, (2 channels, x16), x64 (4 channels, x16)  - Enables the use of fewer components to support wide bus architectures.

Core Voltages: 0.6 V, 1.1 V - Helps reduce power consumption, a key advantage over standard DRAM.

Clock Frequencies: up to 2133 MHz - Provides high performance, high bandwidth, and low power consumption.

Power Consumption - Delivers low power consumption in standby and active modes, plus special mobile features to reduce power for a more efficient design (refer to datasheet for details).

Special Features:

Temperature-compensated self-refresh (TCSR) - Adjusts refresh timing to minimize power consumption at lower, ambient temperaturesPartial-array self-refresh (PASR) - Reduces power by refreshing only critical data

Deep power-down (DPD) - Provides an ultra-low power state when data retention is not required

Programmable drive strength (DS) - Enables adjustment for operation in point-to-point and point-to-2-point applications Programmable VOH signal level - Enables adjustment for operation in point-to-point and point-to-2-point applications Temperature Ranges - Enables high performance in extreme environments: -40 ˚C to +95 ˚C (IT) -40 ˚C to +105 ˚C (AT) -40 ˚C to +125 ˚C (UT Ultra2)

Packages PoP - Saves board space by enabling a Mobile LPDRAM to be stacked on top of a processor so that the two components require only one footprint on the board

Known good die (KGD) - Supports bare die with edge bond pads for easy stacking in SIP and MCP solutions

FBGA - Supports JEDEC-standard FBGA ballout
