DesignWare LPDDR 5/4/4X Controller IP

DesignWare® LPDDR5/4/4X Controller is a next generation controller optimized for power, latency, bandwidth, and area, supporting JEDEC standard LPDDR5, LPDDR4, and LPDDR4X SDRAMs. The controller connects to the DesignWare LPDDR5/4/4X PHY or other LPDDR5/4/4X PHY via the DFI 5.0 interface to create a complete memory interface solution. The DesignWare LPDDR5/4/4X Controller includes software configuration registers, which are accessed through an AMBA 3.0 APB interface.

The LPDDR controller block includes the advanced command scheduler, memory protocol handler, optional inline ECC (Error-correcting code), and dual-channel support, as well as the DFI interface to the PHY.
