LPDDR Controller ASIL B Compliant for LPDDR5X/5/4X for automotive

Overview

Synopsys LPDDR5X/5/4X Controller is a next generation controller optimized for power, latency, bandwidth, and area, supporting JEDEC standard LPDDR5X, LPDDR5 and LPDDR4X SDRAMs. The controller connects to the Synopsys LPDDR5X/5/4X PHY or other LPDDR5X/5/4X PHYs via the DFI 5.0 interface to create a complete memory interface solution. The Synopsys LPDDR5X/5/4X 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. The Synopsys LPDDR5X/5/4X Controller seamlessly integrates with the Synopsys Inline Memory Encryption (IME) Security Module to provide confidentiality of data in-use or stored in off-chip memory.

Key Features

  • Complete, integrated LPDDR5X/5/4X solution from a single vendor when combined with Synopsys’ LPDDR5X/5/4X PHY IP
  • Supports LPDDR5X, LPDDR5 and LPDDR4X protocols
  • DDR PHY Interface (DFI) support for easy integration with industry standard DFI 5.0 compliant PHYs
  • Up to 16 configurable AMBA ports (AXI 4/AXI 3)
  • Enables system designers to extend QoS control into the memory controller
  • Supports a host interface port for easy integration with an external arbiter or non-AMBA on-chip buses
  • Efficient DDR protocol implementation leveraging out-of-order transactions to maximize data throughput, while ensuring starvation avoidance and guaranteeing data coherency
  • Read Reorder Buffer (RRB) substantially improves bandwidth while preserving AXI ordering rules
  • Inline ECC with scrubbing capability – In-line ECC function provides error correction in LPDDR based systems
  • Link ECC for LPDDR5X and LPDDR5
  • APB interface for software accessible registers
  • Optional IME Security Module for LPDDR5X/5/4X Controller
