OPENEDGES' LPDDR5 Memory Subsystem IP Licensed by Aisin for Automotive Application


Seoul, South Korea, April 5th, 2023 --- OPENEDGES Technology, a leading memory subsystem IP provider, today announced that Aisin Corporation has licensed the ORBIT DDR Memory Controller IP (OMC) and ORBIT DDR PHY IP (OPHY) for its high-performance automotive application. Aisin Corp develops components and systems for the automotive industry and is a member of the Toyota Group.

OPENEDGES’ LPDDR5 OPHY and OMC IPs together deliver a top data rate of 6.4 Gbps, demonstrating superior PPA (performance, power, and area). OPENEDGES' integrated IP solution with advanced architecture and proprietary technologies streamlines clients’ design development and verification process, resulting in shorter design cycles with unparalleled benefits.

The OMC is a compact, highly configurable IP that utilizes proprietary out-of-order scheduling algorithms and high-speed implementation techniques. Dynamic address mapping and bank configuration capabilities support frequency changes for optimal efficiency and preservation of DRAM bandwidth. This results in reduced power consumption and improved utilization of area. The OPHY employs a proprietary microcontroller for PHY-independent training, DRAM initialization, and firmware-based DFT features for diagnostics and production testing. A highly configurable channel and floor plan provides implementation flexibility to accommodate connections to different DRAM package types and required lane ordering.

“Automotive SoC requires best-in-class DDR IP for reliability and safety. After a thorough evaluation of IPs in the market, we’ve chosen OPENEDGES LPDDR5 IPs based on performance and quality of service they provide,” said Naruse Takanobu, Chief Engineer of Aisin Corporation.

“OPENEDGES’ IP license with Aisin targeting the automotive market reinforces our leadership,” said Sean Lee, CEO of OPENEDGES Technology, Inc. “The IPs targeting automotive applications are held to a higher standard because automotive applications are interconnected to ensure safety, reliability, and high performance. This license agreement affirms our world-class IP capabilities, demonstrating our commitment to delivering top-notch technology solutions for this demanding industry”.

“At TSS, we are proud to be a part of the OPENEDGES family and contribute to the efforts in delivering cutting-edge DDR PHY solutions to the automotive market," said Richard Fung, CEO of The Six Semiconductor of OPENEDGES. “Our IP license agreement with Aisin is a testament to our commitment to driving progress in the automotive industry. Our team has worked tirelessly to develop IPs that meet the highest standards for safety, efficiency, and performance, and this license recognition is a validation of their hard work and dedication.

In addition to the OPHY licensed by Aisin, OPENEDGES has shown the successful in-silicon operation of its LPDDR4 PHY in 22nm and LPDDR5/4 PHY in 12nm and 14nm. The OPENEDGES LPDDR5X/5/4X PHY IP can be supported in 5nm, 6nm, and 7nm process technologies.
