LoRa may hold the key to zero carbon tracking technology

Wed, Sep 29, 2021

Maintenance-free, energy harvesting can be used for zero carbon asset management. Analogue and mixed-signal semiconductor company, Semtech,

Ryoden, a LoRa ecosystem and network provider have used the RE microcontroller family from Renesas to connect directly to the LoRa Cloud using Semtech’s LoRa Edge platform (LR1110).

LoRa Edge allows for geolocation capabilities driven by energy harvesting, the battery-free energy solution. It also has security features, making it suitable for tracking of personal valuables, transportation and logistics, animals, and healthcare equipment and assets.

Dr. Shiro Kamohara, senior principal specialist from Renesas’ low power product department, says: “The energy harvesting RE family represents the evolution of microcontroller products that have the advantages of being maintenance-free while keeping top-class efficiency. Through our collaboration with Semtech, we are able to offer a cost-efficient green energy solution for our customers.”

The energy-efficient RE family microcontroller is based on the Arm Cortex M0+. It has a built-in controller which can make a battery-less, maintenance-free product. It also has security capabilities that are critical to the IoT and can help protect IoT embedded devices from viral infections and eavesdropping.

When integrated with Semtech’s LR1110, the power consumption of the product is reduced, reports Semtech. Semtech’s LoRa device-to-Cloud platform enables the rapid development and deployment of low power, cost-efficient and long range IoT networks, gateways, sensors, module products, and IoT services worldwide. Semtech’s LoRa technology provides the communication layer for the LoRaWAN standard, which is maintained by the LoRa Alliance, an open IoT alliance for low power wide area network (LPWAN) applications that has been used to deploy IoT networks in over 100 countries. Semtech is a founding member of the LoRa Alliance.

“With the low power nature and end-to-end security of the LoRa Edge platform, the embedded LoRa Basics Modem-E native modem software operating on the LoRaWAN standard, and the LoRa Cloud geolocation and device and application services, the Renesas RE Family is one of the most power-efficient MCUs available on the market,” says Sree Durbha, director of product management in Semtech’s wireless and sensing products group.

Target applications for the LoRa Edge platform with Renesas RE include asset management, tracking of goods through the supply chain and several other use cases requiring continuous indoor or outdoor tracking.

Ryoden is a member of the Mitsubishi Electric Group and is a LPWAN (low power wide area network) communication carrier. It provides data communication services that utilise IoT devices. In addition, the company manages and operates network servers as a network service provider for LoRaWAN communications, and provides related applications and support services.

Siemens enter the IC power analysis market with mPower software

Wed, Sep 29, 2021

Power integrity software from Siemens is claimed to be the only power integrity analysis software available for analogue, digital and mixed-signal IC designs of any size. mPower helps IC designers dramatically boost quality, enhance reliability and speed time to market through accelerated power integrity analysis cycles, says Siemens Digital Industries Software.

The IC power integrity verification software provides virtually unlimited scalability for analogue, digital, and mixed-signal ICs, enabling comprehensive power, electromigration (EM) and voltage drop (IR) analysis for large IC designs.

mPower software delivers power integrity analysis for all versions of 2D designs, in addition to 2.5/3D IC implementations at any scale. It also integrates into existing design flows easily, adds Siemens. mPower can help IC designers to quickly and thoroughly verify designs to meet power-related design goals.

Analog ICs convert physical, data such as sound, motion and video into digital form, and they are increasingly critical to consumer electronics, autonomous vehicles, IoT designs. Siemens explains how mPower replaces rough static analysis and SPICE simulation of select nets to deliver simulation-based EM/IR analysis on large blocks and chips. Customers using mPower have seen overall runtime improvements compared with their current solution, ranging from two times faster to actually completing first-pass EM/IR analysis of large analogue IP blocks, which was previously impossible, reports Siemens.

Siemens’ digital mPower scalable EM/IR engines also provide analysis for all-digital IC designs. This integrates into existing design flows, provides power analysis functionality and requires low per-machine memory into complete verification of even the largest digital design, says the company.

“Before using mPower, we could not do a single-run full chip EM/IR analysis on our 1000+ core 64-bit RISC-V AI chip,” said Darren Jones, vice president of VLSI at AI computer developer, Esperanto. “Using mPower enables us to run our 24-billion transistor 7nm AI chip on our server farm with fewer resources,“ he adds.

The mPower power integrity joins Siemens‘ electro-physical signoff suite addressing power, performance, and reliability analysis which also includes Calibre PERC reliability software, PowerPro software, HyperLynx software, and the Analog FastSPICE platforms.

“Design companies must run both block and full-chip EM/IR analysis to confirm that the power grid delivers the necessary current to the devices, and that wires will not fail prematurely,” says Joe Sawicki, executive vice president for Siemens’ IC EDA Segment. He believes mPower provides a fast, scalable dynamic analysis option for analogue, digital and mixed-signal layouts of any size, as well as silicon-proven accuracy and fast turns for even the largest digital chips, he says.”

Siemens’ mPower power integrity analysis solution for analog, digital and mixed-signal IC designs is available now.

Nanopower primary cell monitors battery health

Tue, Sep 28, 2021

Designed to be placed in series with a primary battery with minimal associated series voltage drop, the LTC3337 is a nanopower primary (non-rechargeable) cell state of health (SoH) monitor with precision coulomb counter, by Analog Devices.

The patented infinite dynamic range coulomb counter monitors and tallies all accumulated battery discharge (battery voltage, battery impedance and temperature) and stores this data in an internal register which is accessible via an I2C interface. The quiescent current consumption is only 100nA, increasing battery run time.

To accommodate a wide range of primary battery inputs, the peak input current limit is pin selectable from 5.0 to 100mA. This enables the IC to present the battery with a load profile which allows it to deliver its maximum capacity, independent of the actual load. This “battery friendly” operation prolongs the lifetime of the cell.

The LTC3337 has eight primary battery peak input current limits, i.e. 5.0, 10, 15, 20, 25, 50, 75 and 100mA. It is intended for use in primary cell applications that require only occasional power such as applications in remote locations, electronic door locks, or glass break detectors. The monitor may also be used in rechargeable battery cell applications.

The 12-lead 2.0 x 2.0mm LFCSP device is available for sampling and is in full production now.

Analog Devices has a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies, serving customers worldwide operating in the industrial, communications, automotive and consumer markets.
