T2M DDR DDR3L/ LPDDR4/ DDR4 Memory PHY IP

DDR3L/ LPDDR4/ DDR4 Memory PHY IP

Description and Features

The DDR3L/ DDR4/ LPDDR4 Combo PHY IP offers low latency and supports throughput of up to 1866Mbps. The PHY IP is silicon validated in the UMC 28HPC+ process technology, complies with the most recent JEDEC requirements, is used to control DRAM devices, to access the data stored in these devices, provide SSTL135, POD12 and LVSTL interfaces for DDR3L, DDR4 and LPDDR4.
