Renesas Introduces Industry’s First Industrial Temperature Grade DDR5 and DDR4 Registered Clock Drivers


New Devices Support Temperatures from -40ºC to 105 ºC; Address Markets Such as Edge Computing and Autonomous Driving

Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today introduced the industry’s first industrial temperature DDR5 (5RCD0148H) and DDR4 (4RCD0232K) registered clock drivers (RCDs). The new devices are targeted at demanding applications such as edge computing, automotive vehicles, industry 4.0, and 5G applications.

The new industrial temp RCDs support temperatures as low as -400C and as high as 1050C, compared to commercial temperature devices that usually operate from 00C to 700C. Renesas’ industrial temperature RCDs support speeds up to 5200 MT/s for DDR5 and up to 3200 MT/s for DDR4. The devices deliver 2X channel speed improvement, low latency and excellent power management, enabling DDR5 industrial temp dual inline memory modules (DIMMs) and memory-down applications, while providing wide temperature range reliability for existing DDR4 applications.

“Emerging segments such as intelligent edge and Open Radio Access Networks (O-RAN) that marry traditional compute and communications architectures together demand server components that can withstand the harsh environments at the network edge,” said Rami Sethi, Vice President and General Manager, Data Center Business Division at Renesas. “Renesas has made a concerted effort, in conjunction with our partners, to qualify our RCD products over extended temperature ranges in order to enable these new markets.”

“It takes a coordinated effort by the memory ecosystem to deliver a wide array of products that reliably extend temperature operating ranges and withstand extreme environmental conditions,” said Malcolm Humphrey, Vice President and General Manager of Core Compute Business at Micron. “Micron’s collaboration with partners like Renesas is opening new markets for the next generation of memory at the intelligent edge.”

Renesas’ industrial temperature memory interface components can be paired with Renesas’ complementary timing, power and 5G RF and baseband offerings to create comprehensive solutions for a variety wireless access and edge computing applications. Renesas’ Winning Combinations are vetted solutions engineered to help customers accelerate designs and get to market faster. Renesas offers more than 250 Winning Combinations that can be found at

Renesas is the longest running supplier of memory interface products in the industry with a history of developing complete chipset solutions since the inception of server memory modules. As part of a complete family of solutions, the new Renesas DDR5 industrial temperature RCD is optimized to work seamlessly with other Renesas components including the P8900 power management IC, the SPD5118 SPD hub, and the TS5111 temperature sensor. The new industrial temperature DDR4 RCD is designed to work with the TSE2004 DDR4 temperature sensor. Memory vendors deploying Renesas chipset solutions are assured of full interoperability and robust quality.


Both the 5RCD0148H DDR5 and 4RCD0232K DDR4 RCDs are available now.
