Integrated and Compact CAN FD system basis chip solution from Microchip

Tue, Dec 17, 2024

The increase in connected applications in the automotive and industrial markets is driving demand for wired connectivity solutions with higher bandwidth, lower latency and enhanced security. Reliable and secure communication networking solutions are vital for transmitting and processing data as intended. Microchip has announced the new family of ATA650x CAN FD System Basis Chips (SBCs) with a fully integrated high-speed CAN FD transceiver and a 5V Low-Drop Voltage Regulator (LDO) available in compact 8-, 10- and 14-pin space-saving packages.

The ATA650x CAN FD SBCs offer a tiny footprint of 2 mm × 3 mm for the VDFN8 package, 3 mm × 3 mm for the VDFN10 package and 3 mm × 4.5 mm for the VDFN14 package. With a built-in high-speed CAN FD transceiver, the SBCs support data transmit and receive rates of up to 5 Mbps.

A solution for space and power-constrained applications, these SBCs exhibit very low power consumption, with a typical sleep current of just 15 μA. The ATA650x SBCs enable control of the VCC supply voltage by the bus signals, which reduces the current consumption of automotive Electronic Control Units (ECUs). To further reduce power consumption, the SBCs can disable the microcontroller supply by switching off LDOs during sleep mode.

The safety features available in the ATA650x device include fail safe, protection and diagnostic functions to provide reliable bus communication in advanced networks. Designed to withstand Electrostatic Discharge (ESD) and equipped with Electromagnetic Compatibility (EMC) performance, the ATA650x devices are robust solutions for applications operating in harsh environments.

The integrated SBC solution is Functional Safety ready to help customers achieve an ISO 26262 safety certification or the desired ASIL level. Additionally, the SBCs are AEC-Q100 qualified with a Grade 0 rating and are designed to operate in temperatures ranging from −40°C to +150°C.

Renesas introduces new AnalogPAK programmable mixed-signal ICs

Tue, Nov 12, 2024

Renesas has announced new AnalogPAK ICs, including lower power and automotive-qualified devices along with the industry’s first programmable 14-bit SAR ADC (Successive-Approximation Register Analog-Digital Converter).

AnalogPAK devices are part of Renesas’ GreenPAK Family of Programmable Mixed-Signal Matrix products: cost-effective, NVM programmable devices which enable innovators to integrate many system functions while minimising component count, board space, and power consumption. GreenPAK and AnalogPAK ICs deliver functional replacement of mixed-signal standard products and stand-alone discrete circuits. They also provide reliable hardware supervisory functions for SoCs and microcontrollers. GreenPAK and AnalogPAK devices provide benefits for virtually any application, including consumer electronics, computing, white goods, industrial, communications, and automotive. Using Go Configure Software Hub and the GreenPAK Development Kit, designers can create and program a custom circuit in minutes.

Renesas’ new SLG47011 AnalogPAK device delivers a new level of performance for configurable analog integrated circuits. It includes a rich set of digital and analog features including programable multichannel 14-bit SAR ADC with Programmable Gain Amplifier (PGA). The SLG47011 also has flexible, user-defined power saving modes for all macrocells that enable designers to switch off some blocks in sleep mode and therefore reduce power consumption to the µA level.

The SLG47011 can be used to extend the performance of, or to offload an MCUs. It can also be used in conjunction with an MCU to replace a complex analog front-end (AFE). Key functions supported by the SLG47011 include measurement, data processing, logic control and data output.

In addition to the SLG47011, Renesas is introducing two other AnalogPAK devices, the cost-optimised SLG47001/3, and the automotive-qualified SLG47004-A.

SLG47001/3 AnalogPAK Devices
The SLG47001 and SLG47003 enable the implementation of precise measurement systems with a low price point and a very compact package to address applications such as gas sensors, power meters, measurement equipment, servers, wearables, industrial robots, industrial and smart home sensor modules.
• Two ultra-low offset op-amps – 9 µV (max.)
• Two 10-bit digital rheostats
• Six-channel sampling comparator
• Analog switch
• Voltage reference
• 59-bytes pattern generator
• 2k/10k/25MHz oscillators
• Fully configurable blocks: LUTs, flip-flops, shift registers, timers, counters, delays

SLG47004-A AnalogPAK Device
The SLG47004-A delivers the functionality of the SLG47004 devices with the addition of automotive qualification Grade 1 for applications such as infotainment, navigation, chassis and body electronics, automotive display clusters and more. The new devices support a temperature range of -40°C to 125°C.

Device Availability
All of the new AnalogPAK devices are available today from Renesas and its authorised distributors, along with customised development kits. The SLG47011 comes in a 2.0 x 2.0 mm 16-pin STQFN package. The SLG47001 is packaged in a 2.0 mm x 3.0 mm 20-pin STQFN, while the SLG47003 comes in a 3.0 mm x 3.0 mm 24-pin STQFN. The SLG47004-A is available in a 4.0 mm x 4.0 mm 24-pin TQFN.

Imagimob’s Edge AI solutions are now available for the AURIX product family

Tue, Oct 08, 2024

Autonomous and automated driving is a megatrend in the automotive industry, along with electrification. AI plays a critical role in this trend, enabling vehicles to detect pedestrians, analyse driver behaviour, recognise traffic signs, and control trajectories, among many other use cases. A key enabler of this is Edge AI, as autonomous and automated driving is highly dependent on the need for AI systems with machine learning capabilities and processors that can handle large amounts of data in parallel, safely, secured, and in real time. To address this challenge, Imagimob, an Infineon company, has enhanced its automotive machine learning portfolio by integrating machine learning capabilities into Infineon’s Automotive ASIL-D complaint MCUs like AURIX TC3x and AURIX TC4x.

“The integration of secured and dependable AI capabilities into microcontroller families is crucial for advancing autonomous driving applications in the automotive industry,” said Thomas Boehm, Senior Vice President Microcontroller at Infineon. “We are proud that our AURIX microcontrollers are now supported by Imagimob Studio, making them accessible to developers worldwide. This highlights our role as a leading innovator in the industry.”

“With the integration of AURIX into our Imagimob Studio, we are bringing full machine learning (ML) compatibility and capabilities to the automotive sector,” said Alexander Samuelsson, CTO of Imagimob. “This means that all the use cases we support with our platform are now also available for Infineon’s AURIX microcontrollers.”

With Imagimob Studio, developers can now create robust ML models for the Edge and deploy them onto Infineon’s proven AURIX MCUs. The process starts with creating machine learning models in Imagimob Studio. Once the AI model is complete, users can select to deploy on the MCUs directly within the platform. They are then guided through steps on how to deploy the code seamlessly, simplifying the implementation of machine learning on MCUs and enabling the creation of sophisticated ML models. In addition, Imagimob Studio offers a sample project for siren detection, demonstrating model creation and deployment. By using the code example, users can also learn how to create acoustic models with AURIX MCUs and a microphone shield. Furthermore, Imagimob has developed new regression models that can be used to calculate remaining battery power, health status, and usage time.

The AURIX TC4x scalable MCU family offers a seamless upgrade path from the AURIX TC3x family of ASIL-D compliant automotive MCUs. This enhanced performance is powered by the next-generation TriCore 1.8. In addition, the AURIX TC4x features a scalable accelerator suite that includes a parallel processing unit (PPU) and multiple intelligent accelerators to support cost-effective AI integration. For the AURIX TC4x family, these advancements translate into enhanced machine learning capabilities, enabling developers to deploy multiple models simultaneously or more complex ones. For instance, while the AURIX TC3x can handle basic siren detection, the AURIX TC4x enables both siren detection and voice interaction simultaneously.
