Analog Devices Industrial Inertial Measurement Units

Analog Devices has announced a series of five inertial measurement units (IMUs) that address the navigation and safety-related needs of industrial applications in several emerging markets, while also reducing their system complexity and cost. The ADIS16470, ADIS16475 and ADIS16477 IMUs deliver performance improvements in a small size factor with a standard surface mount assembly.

Together, these products bring a previously unavailable performance-for-cost ratio to unmanned aerial vehicle (UAV) applications where designers have previously struggled with risky and sub-par performance solutions from integrating consumer grade sensors, which also fell short of reliability goals.

Additional technical specifications are available on Analog Devices’ website.


Intersil Radiation-Hardened Quad Power Supply Sequencers

Intersil has introduced the ISL70321SEH and ISL73321SEH quad power supply sequencers designed to drive point-of-load (POL) regulators that power FPGAs and complex, multi-rail power systems. Highly scalable, up to four power supplies can be sequenced by a single device, or multiple devices can be cascaded to sequence an unlimited number of power supplies. Intersil's radiation-hardened power supply sequencers ensure reliability with fault monitoring to boost system health and performance, and they are backed by single event effects (SEE) mitigation tests and complete radiation assurance testing.

To ensure accurate monitoring and reliable system operation, the products integrate precision input comparators with an input threshold voltage of 600mV ±1.5 percent to deliver greater accuracy when monitoring power supply voltages. Both devices actively monitor seven different fault conditions to provide comprehensive fault detection, and a DONE indicator gives system feedback that power-up and power-down have completed successfully.

Microsemi has announced the launch of its TimeProvider 4100, an IEEE 1588 Precision Time Protocol (PTP) grandmaster clock designed to scale from the edge to the aggregation layers of both mobile infrastructure and access networks.

The TimeProvider 4100 is a gateway clock, a class of synchronization product which accepts multiple inputs from Global Navigation Satellite Systems (GNSS), Synchronous Ethernet (SyncE), 1588 PTP and E1/T1 digital transmission links, and distributes timing flows to multiple endpoints such as base stations. A gateway clock benefits from multiple layers of protection utilizing other assets in the core of the network. TimeProvider 4100 is complemented by extensive port fan-out for PTP, Network Time Protocol (NTP), SyncE and legacy building integrated timing supplies (BITS). With multiple ports for current, legacy and future networks which can be connected to multiple base stations for 4G and 5G deployments, the device offers users a cost-effective solution that can be adapted for a variety of use cases.

Information concerning pricing and availability can be found on Microsemi’s website.


RS Components Arduino-style Shields

RS Components has introduced a range of Pmods (peripheral modules) and shields from Digilent. Enabling makers and engineers to build the bridge from systems to the physical world, the devices can be used in a variety of applications. These include single-board-computer designs and Internet of Things (IoT) projects that require additional capabilities, such as wireless communications including Bluetooth and Wi-Fi; MEMS devices such as three-axis gyroscopes, accelerometers and microphones; or motor control.

Compatible with the Arduino R3 footprint, the chipKIT Pmod shield enables users to connect to more than 80 Pmods, augmenting the capabilities of system boards and thereby extending the functionality of designs and the range of possible applications. The shield has five 2x6 Digilent Pmod connectors, one 2×4 I²C connector and optional pull-up resistors for the I²C bus.

Texas Instruments (TI) has unveiled its MSP430 microcontrollers (MCUs) for sensing applications. Developers can now implement sensing solutions through a multitude of integrated mixed-signal features in this family of MSP430 value line sensing MCUs. Additions to the line include two entry-level devices and a TI LaunchPad development kit for quick and easy evaluation.

Key features include a common core architecture, a tools and software ecosystem and extensive documentation including migration guides that make it easy for developers to choose the best MSP430 value line sensing MCU for each of their designs. Additionally, designers can scale from the 0.5-KB MSP430FR2000 MCU to the rest of the MSP430 sensing and measurement MCU portfolio for applications that require up to 256 KB of memory, higher performance or more analog peripherals.
