8Mbit serial flash memory has small form factor for IoT devices

Fri, Jul 21, 2023

The first of a series of 3V RV flash memories has been announced by Winbond Electronics. The W25Q80RV is an 8Mbit flash device capable of high performance, low power, and available in a small form factor for connected IoT edge devices used in industrial and consumer segments.

It can support fast software updates for products deployed in industrial factory automation and smart home control applications combining processing, connectivity, and sensor technologies, explained Winbond.

The W25Q80RV is manufactured in Winbond’s 12-inch wafer foundry utilising the latest generation of its 58nm technology. The die area is reduced by 40 per cent compared to its predecessor which was built with 90nm technology. The flash memory is suitable for space-constrained applications where the flash KGD or WLCSP is combined with the SoC in a system in package.

Read speed has also improved from 104MHz to 133MHz, with page programming time reduced by 50 per cent and active read current reduced by up to 20 per cent. All combine to “significantly optimise” system functions. XIP (eXecute-In-Place) of code is accomplished at a high frequency, enabling greater system response while consuming less energy.

Faster programming accelerates factory throughput and lowers manufacturing costs. The short time it takes to conduct an over the air (OTA) firmware update means greater system availability and less downtime, added the company.

The W25Q80RV supports all common single/dual/quad/QPI commands and read modes for XIP and code shadowing to RAM. This device operates on a single 2.7V to 3.6V power supply with a power-down current down to 1microA. Active read current is optimised from 12mA down to 10mA at 104MHz.

The 8Mbit (1Mbyte) flash is sectioned into 64kbyte or 32kbyte blocks and is further subdivided into small 4kbyte sectors for flexibility and storage efficiency in applications that require code, data, and parameter storage in the same device, said Winbond. It is also capable of 66MHz DDR (double data rate) operation enabling the system to achieve the same high speed (133MHz single data rate) read throughput at a lower clock frequency. The read command bypass mode supports faster memory access for true XIP operation by eliminating the command input cycle.

W25Q80RV is available now. This 8Mbit flash memory device is the first in a series, Winbond said it will release other members and densities of the RV series in coming months, enabling migration from existing W25QxxCV and W25QxxDV series to the W25QxxRV counterparts.

Keysight unifies multi-speed Ethernet performance test for data centres

Fri, Jul 21, 2023

Layer one to three Ethernet testing is provided on a single platform by Keysight’s AresONE-M 800GE. It supports data centre interconnect speeds from 10GE to 800GE and validates network equipment interoperability and bandwidth performance to support transition to 800GE, said the company.

Data-intensive applications such as AI, high resolution video streaming, the IoT, 5G, edge computing and cloud computing require a secure and reliable 800GE network infrastructure, Keysight explained. Deploying 800GE into existing network infrastructures creates complex testing challenges for network engineers, introducing a variety of new and legacy networking protocols, multiple Ethernet speeds and an array of fibre and copper data centre interconnects (DCI). To properly validate the performance of network infrastructures and network system designs, equipment manufacturers and network operators must have a flexible test platform that can scale to evaluate mixed-speed networks while supporting a broad set of connections and network protocols.

The Keysight AresONE-M 800GE delivers the only Layer 1 to Layer 3 Ethernet networking and infrastructure test, said Keysight, supporting comprehensive DCI speeds from 10GE to 800GE in a single platform. Its range of capabilities enables design engineers and data centre operators to validate networking equipment interoperability and bandwidth performance while supporting the transition to 400GE and 800GE networks with the capability to also test slower, legacy Ethernet speeds.

In addition to comprehensive Ethernet speeds of 1x 800GE, 2x 400GE, 4x 200GE and 8x 100GE, it supports PAM4 and NRZ signalling. The AresONE-M 800GE features 106.25Gbit per second host electrical lane signalling with the ability to downshift to the lower electrical lane speeds of 53 and 25Gbits per second for 400GE and 100GE speeds.

The single test platform supports all required forward error correction (FEC) types and a full array of in-depth link tuning, stability, reliability, and performance measurement statistics.

It also provides the protocol support required to test enterprise, metro, and cloud-capable Layer 2 and Layer 3 switching and routing network equipment through the IxNetwork software application.

It is claimed to have the highest port density available today for 800GE test systems with support for eight ports in a single, two-rackmount unit chassis with additional configurations for two and four ports.

The AresONE-M 800GE uses an integrated physical layer digital signal processor (DSP) from Credo Technology Group for fast and efficient data transfer with low latency that enables data transit requirements of hyperscalers, enterprises, 5G carriers and service providers. The DSP is also claimed to optimise power consumption to reduce operational costs, minimise heat dissipation and meet energy-efficient standards for advanced networks.

Renesas develops power management reference design for Versal adaptive SoC

Thu, Jul 20, 2023

A space-ready reference design for the AMD Versal adaptive SoC, XQRVC1902, has been developed by Renesas in collaboration with AMD.

The ISLVERSALDEMO2Z reference design integrates key radiation-hardened (rad-hard) components for power management in a compact design. It includes four new and recently released Intersil ICs, specifically designed to support a range of power rails for space avionics systems that demand tight voltage tolerances, high current, and efficient power conversion in addition to the capability to withstand the harsh environment of space.

The Versal Adaptive SoC is a space-grade compute platform that delivers full radiation tolerance, accelerated AI inference and high bandwidth signal processing, said Renesas. The ISLVERSALDEMO2Z generates each of the power rails used by the Versal platform, including a low 0.80V core voltage supply that can source up to 140A of current.

As core voltages decrease and currents increase for FPGAs and ASICs, it has become more difficult to meet the stringent power requirements of these devices to ensure that they operate error-free, explained Renesas. This is especially critical in space missions where power availability is limited and systems are exposed to extreme temperatures and radiation for an extended period of time.

The reference design “has been meticulously engineered to meet the rigorous demands of operations in space, while integrating all of the essential components into a very small footprint. It is an ideal turnkey solution for Versal Adaptive SoC power management,” commented Chris Stephens, vice president and general manager of the HiRel business division at Renesas.

The reference design comes with an array of power management devices that have been tested and verified to withstand exposure to high levels of radiation.

It includes the ISL73847SEH rad-hard dual output PWM controller, ISL73041SEH and ISL71441M, believed to be the industry’s first dedicated Gan FET half bridge drivers for space applications and the ISL73007SEH rad-hard PoL regulator.

The devices used are in packages with small footprints resulting in the core power rail components taking up just 104 square cm of board area, or approximately the size of two business cards.

The ISLVERSALDEMO2Z comes with all of the design files that customers need for rapid integration into their systems, including schematics, bill of materials and PCB Gerber files.

All products are available today and the reference design is available upon request in limited quantities.

The reference design and the new products will be demonstrated at the Renesas booth (112/113) at the IEEE Nuclear & Space Radiation Effects Conference (NSREC), July 24-28, in Kansas City, Missouri, USA.
