Micron Technology LPDDR5/LPDDR5X SDRAM

For applications that require low power, high bandwidth, and small footprints

LPDDR5 is the latest generation of Micron low power SDRAM and it delivers higher density in the same footprint but with lower power consumption and a higher data transfer rate than the previous generation. Emerging technologies, such as 5G mobile technology and autonomous driving, require a memory subsystem that needs a larger bandwidth to support real-time computing and data processing. Micron’s LPDDR5 SDRAM addresses the growing demand for higher memory performance and lower energy consumption across a wide array of markets, including automotive, client PCs and networking systems built for 5G and AI applications.

Key features

Densities: 16Gb to 128Gb - Provides higher density in a similar footprint
Configs: x16,x32,x64 - Enables the use of fewer components to support wide bus
Lower Core and IO power helps reduce power consumption
Data rates: 6400Mb/s(LPDDR5)/8533Mb/s(LPDDR5x) -up to 2 times faster to LPDDR4X

Additional features

Densities: 16Gb to 128Gb - Provides higher density in a similar footprint, more flexibility to support more application designs than the previous technology.
Configurations: x16, x32, x64 - Enables the use of fewer components to support wide bus architectures. LPDDR5 supports 32Gb per channel vs. LPDDR4’s 16Gb per channel.
Core Voltage/IO Voltage: 1.05V, 0.50V - Lower Core and IO power helps reduce power consumption, a key advantage over standard DRAM (see datasheets which may also support 0.45V or 0.60V VDDQ options).
Data rates: 6400Mb/s(LPDDR5) / 8533Mb/s(LPDDR5x) - Up to two times faster compared to LPDDR4X at 4266Mb/s (Micron LPDDR4X data rates 4266Mb/s compared to max. LP5DDRX data rates 8533 Mb/s).
Power Consumption: 15% I/O energy reduction compared to LPDDR4X with new power saving features - Delivers low power consumption for a more efficient design (Energy reduction is attributed to lower VDDQ (0.5V for LPDDR5/LPDDR5X) compared to LPDDR4X VDDQ= 0.6V and additional power saving features ).
