Fri, Oct 08, 2021

An automotive gateway solution with R-Car S4 system on chips (SoCs) and power management ICs (PMICs) for next-generation vehicle computers, communication gateways, domain servers and application has been launched by Renesas. The new solution meets the automotive industry’s requirements for high performance, high-speed networking, high-security and high-functional safety levels that are required as E/E architectures evolve into domains and zones. The solution enables software reusability and includes the new best-in-class PMICs designed to work seamlessly with the R-Car S4.

The Renesas R-Car S4 is one of the first products in Renesas’ 4th-generation R-Car family. It includes multiple Arm Cortex A55, Cortex R52 and the company says it is the first to implement an RH850 MCU for control domain management. R-Car S4 SoCs offer automotive interfaces such as 16x CAN FD, 16x LIN, 8x SENT, 1x FlexRay, 4x PCIe V4.0 and also a high-bandwidth 3 x 2.5Gbit ethernet switch to enable rich communication and connectivity options inside and outside the vehicle.

This automotive solution means designers can re-use up to 88 per cent of software code developed for third generation R-Car SoC and RH850 MCU applications. The software package supports R-Car S4 application development including the real-time cores with various drivers and basic software such as Linux BSP and hypervisors. In addition, a virtual platform is available from a partner company enabling early software development and evaluation to help reduce design time and cost.

The new PMICs provide advanced power modes that support low power operation. The RAA271041 PMIC accepts the vehicle’s 12V supply and supports wide operation for load dump and cold cranking pulses while providing the first-stage regulation. The RAA271005 is a Safe 11-channel PMIC that takes the RAA271041’s output and steps it down further to the various supply voltages needed by R-Car S4 and its peripherals such as LPDDR4x memory. The RAA271041 and RAA271005 PMICs provide a complete power solution from vehicle battery down to system voltage.

Microchip and Acacia link to support bandwith growth

Thu, Oct 07, 2021

Data Centre Interconnect (DCI) and metro optical transport network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support bandwidth growth driven by the expansion of data centres and 5G network buildouts. Microchip Technology and Acacia, part of Cisco, are supporting this transition by bringing to market interoperable solution sets consisting of Microchip’s DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics.

The aim of the collaboration is to establish an ecosystem to support 400G CFP2-DCO, QSFP-DD and OSFP modules for the 400ZR specification as well as the OpenZR+ and Open ROADM multi-source agreement (MSA) applications.

For converged packet/OTN optical platforms, Microchip’s DIGI-G5 and Acacia’s 400G CFP2-DCO module are designed to enable terabit-class OTN switching line cards, muxponders, and switchponders. The DIGI-G5 interoperates with Acacia’s 400G CFP2-DCO module using a Flexible OTN (FlexO) or NxOTU4 interface to efficiently support OTN traffic, including Open ROADM MSA interface modes and 200G/400G ITU-T standards currently being drafted.

For compact modular optical systems, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable 400G flexible line rate muxponders/transponders with support for multiple client optics types including QSFP28, QSFP-DD, and OSFP modules, helping service providers to transition from 100 GbE to 400 GbE using the same hardware.

For data centre routing and switching platforms, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable dense 400 GbE or FlexE with per port MACsec encryption coherent line cards. This helps customers leverage IP routers/switches over DWDM (IPoDWDM) infrastructure in DCI deployments.

“DIGI-G5 and META-DX1 have enabled our optical transport, IP routing and Ethernet switching customers to implement a new class of multi-terabit OTN switching and high-density 100/400 GbE and FlexE line cards that deliver on stringent packet timing and integrated security capabilities for the build out of cloud and carrier 5G-ready optical networks,” said Babak Samimi, vice-president for Microchip’s communications business unit. “Our interoperability efforts with Acacia help to demonstrate that an ecosystem for volume deployment of these new line cards with pluggable 400G coherent optics exists.”

“With Acacia’s 400G coherent modules verified to interoperate with Microchip’s DIGI-G5 and META-DX1 devices, we see it as a robust solution designed to address network capacity growth and improved efficiency,” said Markus Weber, senior director DSP, product line management of Acacia, now part of Cisco. “The compact size and power efficiency of our 400G OpenZR+ CFP2-DCO modules were designed to help network operators deploy and scale capacity of high-bandwidth DWDM connectivity between data centres and in metro networks.”
