Xilinx ships Versal ACAP devices

Xilinx has announced that it has shipped Versal AI Core series and Versal Prime series devices to multiple tier one customers through the company’s early access program.

Versal is the industry’s first Adaptive Compute Acceleration Platform (ACAP), described as heterogeneous compute devices with capabilities that far exceed those of conventional CPUs, GPUs, and FPGAs.

The integrated, multi-core, heterogeneous compute platform can be changed at both the hardware and software levels to dynamically adapt to the needs of applications and workloads in data centre, automotive, 5G wireless, wired and defence markets.

The Versal ACAP is natively software programmable and its architecture features a flexible, multi-Tbit per second network on chip (NoC). By seamlessly integrating all engines and key interfaces, the NoC ensures that the ACAP is available at boot and easily programmed, whatever a developer’s specialism, be they software developers, data scientists or hardware developers, says Xilinx. Tools, software, libraries, IP, middleware, and frameworks are available to dynamically customize accelerated computing using industry-standard design flows.

The Versal ACAP portfolio is based on TSMC’s 7nm process technology ad is claimed to be the first platform to combine software programmability with dynamically configurable domain-specific hardware acceleration. It includes a mix of next-generation scalar engines for embedded compute, adaptable engines for FPGA silicon programmability, and intelligent engines for AI inference and advanced signal processing for advantageous raw performance and performance per Watt capabilities compared to CPU and GPU implementations, adds Xilinx.

The Versal AI Core series delivers the portfolio’s highest compute and lowest latency, for AI inference throughput and performance through the AI Engine. This core is optimised for cloud, networking and autonomous technology and is claimed to offer the highest range of AI and workload acceleration available in the industry.

The Versal Prime series is optimised for connectivity and in-line acceleration to operate across multiple markets and a diverse set of workloads, continues the company.

Both the Versal AI Core series and Versal Prime series include multiple devices, each with dual-core Arm Cortex-A72 application processors, dual-core Arm Cortex-R5F real-time processors, over 2m logic cells of adaptable hardware, and over 3,000 DSP engines optimised for high-precision floating point and low latency. The Versal AI Core devices offer up to 400 AI Engines optimised for AI inference and advanced signal processing workloads.

The Versal portfolio includes four additional series of devices, architected to deliver scalability and AI inference capabilities for diverse applications, from cloud and networking to wireless communications, edge computing, and endpoints.

The Versal AI Core and Versal Prime series will be generally available in the second half of 2019.

Miniature tact switches save PCB space for home automation

Two sub-miniature tact switches, the PTS636 and PTS526, save PCB space for design engineers developing home automation and IoT electronic devices, says C&K.

The space savings electronics designers to add other components on the PCB. The PTS636 switch has a 6.0 x 3.5mm footprint and an adjustable thickness of 2.5, 4.3 and 5.0mm; the PTS526 has a footprint of 5.2 x 5.2mm and an adjustable thickness of 0.8 to 2.0mm. Both offer a large actuation surface for easier integration, for applications such as home automation, IoT devices and e-cigarettes, as well as control systems for items such as drones, e-bikes and robot vacuum cleaners.

The PTS526 and PTS636 switches are manufactured in surface mount technology. The PTS636 is additionally made in through hole format. Both use a hard actuator, ensuring that it can be fully integrated into standard processes, with no need for an additional interface button. This functionality reduces time and costs for an end equipment manufacturer, points out C&K. The switches provide optimum performance and retains high reliability up to 500,000 cycles.

The PTS636 design includes a 2.5mm height version with integrated ground pin and the PTS 526 design includes a version with an integrated ground pin. There is ESD protection soldered to the PCB for routing unwanted electrical overload.   

The PTS 636 is available in four different operating-force levels 130, 180, 250 and 320gf. There are three actuation forces for the PTS 526: 160, 260 and 320gf. Both sets of switches are rated at 50mA, have a bounce time of less than 10ms and an operating temperature range of -20 to +70 degrees C.

C&K was founded in 1928 and manufactures electromechanical switches. It has more than 55,000 standard products and 8.5 million switch combinations for use in automotive, industrial, IoT, wearables, medical, telecomms, consumer products, aerospace and point of sale (POS) terminals.

C&K products include tactile, pushbutton, snap-acting, toggle, rocker, detect, DIP, keyswitch, navigation, rotary, slide, switchlock, thumbwheel, smart card readers, high-rel connectors and custom assemblies.

Infineon claims Hall sensor is a first for ASIL D systems

Infineon Technologies believes that the Xensiv TLE499913 is the industry’s first monolithically integrated linear Hall sensor developed entirely according to the safety standard ISO26262 for automotive applications.

The single sensor enables the development of fault-tolerant systems that have to meet the highest level of functional safety (ASIL D), says Infineon, such as electric steering systems, electric throttle control systems, and pedal applications.

ISO26262 requires a system to keep functioning even if a single fault occurs, or a single components fails. The TLE4999I3 allows uninterrupted operation at system level. It consists of a monolithic design with two independent Hall elements. Their signal paths are separate from each other and internal control mechanisms carry out a plausibility check of the sensor data already within the chip. The linear Hall sensor also provides extensive status information to the system.

In addition to functional safety, the TLE4999I3 also offers very high magnetic sensitivity with an error tolerance of less than two per cent. The offset error drift, another important parameter for magnetic sensors as it determines the absolute position in a magnetic field, is maximum 100 microT, or half that of comparable products, claims Infineon. The values of these parameters apply across the entire temperature range and lifetime of the product.

The TLE4999I3 allows two magnetic ranges of ±12.5 and 25mT to be adjusted. These low values allow the use of relatively small and, consequently, inexpensive magnets.

A PSI5 communication interface is a current interface, requiring little wiring and offering “an excellent electromagnetic performance” according to Infineon. The TLE4999I3 is suitable for applications in which it is connected to the control unit over large distances as it supports cable lengths up to 12m.

The TLE4999I3 sensor is supplied in a PG-SSO-3 package and is qualified according to AECQ100, Grade 0 for use in applications with ambient temperatures of 150 degrees C during average operational conditions.

Infineon will be exhibiting this and other sensor solutions at the Sensor+Test 2019 trade fair (Nuremberg, 25 to 27 June 2019) Hall 1 – booth 429.
