DDR4 and DDR5 clock drivers address autonomous driving

Believed to be the industry’s first industrial temperature DDR5 and DDR4 registered clock drivers (RCDs), the 4RCD0232K and 5RCD0148H operate at industrial temperatures. Renesas says the 5RCD0148H (DDR5) and 4RCD0232K (DDR4) RCDs target demanding applications such as edge computing, automotive vehicles, industry 4.0 and 5G applications.

The industrial temp RCDs support temperatures as low as -400 degrees C and  up to +1050 degrees C; commercial temperature devices usually operate from 0 to +700 degrees C. The industrial temperature RCDs support speeds up to 5200M transfers per second for DDR5 and up to 3200M transfers per second for DDR4. The devices deliver a two-fold channel speed improvement, low latency and power management, enabling DDR5 industrial temp dual inline memory modules (DIMMs) and memory-down applications, while providing a wide temperature range for existing DDR4 applications, says Renesas.

“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,” explains Rami Sethi, vice president and general manager, data centre business division at Renesas. 

Renesas’ industrial temperature memory interface components can be paired with its complementary timing, power and 5G RF and baseband offerings to create a variety of wireless access and edge computing applications. 

Renesas supplies memory interface products and chipsets. The DDR5 industrial temperature RCD is optimised to work seamlessly with other Renesas components including the P8900 power management IC, the SPD5118 SPD hub and the TS5111 temperature sensor. The DDR4 RCD is designed to work with the TSE2004 DDR4 temperature sensor. 

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