Industry’s first industrial temperature grade DDR5 and DDR4 registered clock drivers

Update: November 12, 2021

Renesas Electronics has released what is claimed to be the industry’s first industrial temperature DDR5 (5RCD0148H), and DDR4 (4RCD0232K) registered clock drivers (RCDs). The new devices are aimed at demanding applications, including edge computing, automotive vehicles, industry 4.0, and 5G applications.

The new industrial temp RCDs support temperatures as low as -400C and high as 1050C in comparison to commercial temperature devices that ordinarily operate from 0C to 700C. Its industrial temperature RCDs support speeds up to 5200MT/s for DDR5 and up to 3200MT/s for DDR4. The devices provide 2X channel speed improvement, low latency and excellent power management, allowing DDR5 industrial temp DIMMs and memory-down applications while giving 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.”

The company’s industrial temperature memory interface components can be paired with its complementary timing, power and 5G RF and baseband products to produce comprehensive solutions for multiple wireless access and edge computing applications.
