LPDDR5X/5/4X/4 combo PHY at 7nm

OPENEDGES, the memory system IP provider, including DDR memory controller, DDR PHY, on-chip interconnect, and NPU IP together as an integrated solution or independent IP. They are tightly combined to bring synergy for high performance and low latency. OPENEDGES' integrated IP solutions are market and silicon-proven, featuring advanced architectures and proprietary technologies that enable customers to shorten their design and verification processes.

The LPDDR5X/5/4X/4 Combo OPHY introduces support for LPDDR5X speed bins and beyond, on top of the previously supported LPDDR5, 4X, 4 operating modes and speed bins. As with its predecessors, the 7nm LPLDDR5X/5/4X/4 OPHY test chip was brought up quickly in the lab and has achieved 8533 Mbps operation, the current maximum data rate for LPDDR5X, with dual-rank DRAM. The LPDDR5X OPHY will demonstrate quad-rank support in the near future. Also, it integrates key enhancements to its unique architecture, designed to enable maximum performance and flexibility while maintaining a footprint that is highly competitive to alternative LPDDR PHY solutions. In addition to the introduction of LPDDR5X support up to 8533 Mbps, the available configuration has been expanded to both 1x16 and 1x32, verified and ready for customer integration.

Supported Standards:
- JESD209-5A Low Power Double Data Rate 5 (LPDDR5)
- JESD209-5B Low Power Double Data Rate 5 (LPDDR5X)
- JESD209-4D Low Power Double Data Rate 4 (LPDDR4)
- JESD209-4-1 Low Power Double Data Rate 4X (LPDDR4X)
