SoM and starter kit accelerate development for motor control and DSP applications 

Additions to the Kria portfolio of adaptive system on module (SoM) and developer kits have been announced by AMD. The Kria K24 SoM and KD240 Drives starter kit are available to order now.

The Kria K24 SoM offers power-efficient compute in a small form factor and targets cost-sensitive industrial and commercial edge applications, explained the company. InFO (integrated fan-out) packaging results in the K24 being half the size of a credit card while using half the power of the larger, connector-compatible Kria K26 SoM. 

It provides high determinism and low latency for powering electric drives and motor controllers used in compute-intensive DSP applications at the edge, such as electric motor systems, robotics for factory automation, power generation, public transportation such as elevators/lifts and trains, surgical robotics and medical equipment such as MRI beds, and also EV charging stations. 

The KD240 Drives starter kit is a motor control-based development platform. Coupled with the 24 SoM, users can quickly develop motor control and DSP applications at a reduced time to market and without requiring FPGA programming expertise. 

The K24 SoM features a custom-built Zynq UltraScale+ MPSoC device and the supporting KD240 starter kit is a sub-$400 FPGA-based motor control kit. Enabling developers to begin at a more evolved point in the design cycle, the KD240 provides easy access for entry-level developers compared to other processor-based control kits.

The K24 SOM is qualified for use in industrial environments with support for more design flows than any generation before it, said AMD. That includes familiar design tools like Matlab Simulink and languages like Python with its extensive ecosystem support for the PYNQ framework. Ubuntu and Docker are also supported. Software developers can also use the AMD Vitis motor control libraries while maintaining support for traditional development flows.

“The K24 SOM delivers high performance-per-watt in a small form factor and houses the core components of an embedded processing system on a single production-ready board for a fast time to market,” said Hanneke Krekels, corporate vice president, Core Vertical Markets, AMD. 

It is estimated that around 70 per cent  of the total global electrical use by the industrial sector is tied to electric motors and motor-driven systems. AMD said that even a one per cent improvement in the efficiency of a drive system can have a significant positive impact on operational expenses and the environment. 

The KD240 is supported by an optional motor accessory pack (MACCP), with additional motor kits available in the future that can be purchased separately for an enhanced ramp-up experience for developers. 

K24 SOMs are offered in both commercial and industrial versions and are built for 10-year industrial lifecycles. In addition to support for expanded temperature ranges, the industrial-grade SoM includes ECC-protected LPDDR4 memory for high-reliability systems. 

The K24 commercial version is shipping today, and the industrial version is expected to ship in Q4.

Dual output Hall-effect sensors save space while detecting speed and direction

For high voltage, automotive and industrial applications, the AH39xxQ series of Hall-effect sensors provide speed and directional data, said Diodes.

The high-voltage, dual output, automotive-compliant sensors provide accurate speed and directional data or two independent outputs. They are designed for industrial and automotive applications such as detecting rotational and linear speed/direction and determining the angular position of a rotating shaft.

They operate over a wide supply voltage range of 2.7 to 27V to meet automotive battery requirements.  They also have a 40V absolute maximum rating, enabling them to safely handle 40V load dumps. 

There is also -18V of reverse voltage protection to guard against incorrect battery connections. 

For added robustness, the ESD (electrostatic discharge) protection exceeds the automotive norms of 5kV human body model (HBM) and 2kV charge device model (CDM).

Three BOP/BRP (operating/release) options are offered, with typical values of 10/-10, 25/-25 and 75/-75 Gauss and the narrow operating window ensures accurate and reliable switching points, confirmed Diodes. 

Dual-channel operation means these sensors can replace two latch switches, reducing both PCB space and overall component costs. Combining chopper-stabilised amplifiers with an advanced Hall plate design mitigates switch point drift, ensuring accurate measurements over a broad temperature range. 

The self-diagnostic features make the AH39xxQ sensors suitable for ISO 26262-compliant systems. There is also a safe operating mode which is entered if an error, such as over-temperature or under-voltage lockout, is detected.

The AH39xxQ series Hall-effect sensors from Diodes are AEC-Q100 Grade 0 qualified, manufactured in IATF 16949 certified facilities, and support PPAP (production part approval process) documentation. 

They are supplied in TSOT25 packages. 

Diodes supplies semiconductor products to the world’s leading companies in the automotive, industrial, computing, consumer electronics, and communications markets. Its product portfolio consists of discrete, analogue and mixed-signal products and packaging technology.

The company has worldwide operations of 32 sites, including engineering, testing, manufacturing.

MAC-PHY devices connect automotive devices with 10BASE-T1S Ethernet

A family of LAN8650/1 MAC-PHY devices developed by Microchip Technology can be used to connect low-cost microcontrollers without a built-in Ethernet MAC (media access controller) to a 10BASE-T1S Ethernet network.
In automotive designs, 10BASE-T1S technology makes it possible for low speed devices to connect to a standard Ethernet network, eliminating the need for dedicated communication systems. Expanding its portfolio of automotive-qualified Ethernet solutions, the LAN8650 and LAN8651 MAC-PHYs are qualified for automotive applications. They include a MAC and SPI (serial peripheral interface) to connect devices at the edge of automotive networks.
The built-in MAC and SPI enable designers to connect 8-, 16-, and 32-bit microcontrollers that do not have a built-in Ethernet MAC to 10BASE-T1S SPE (single pair Ethernet) networks. As a result, sensors and actuators that interface between the digital and the real world to become part of an all-Ethernet architecture. Connecting to even the simplest microcontrollers can reduce the overall size and cost of a design, said Microchip.
Matthias Kaestner, corporate vice president of Microchip’s automotive business, commented: “This new technology will connect sensors and actuators in the physical world all the way to the cloud, enabling a seamless Ethernet architecture in vehicles, which in turn reduces development effort and time to market”.

These devices are equipped with time-sensitive networking (TSN) support, which allows for synchronised timing across Ethernet networks. This synchronisation is critical for many automotive applications such as advanced driving assistance systems (ADAS).
The automotive-qualified LAN8650/1 devices comply with AEC-Q100 Grade 1 for enhanced robustness in harsh environments, including extended operational temperature range from -40 to +125 degrees C.  They are also functional safety ready and designed for use in ISO 26262 applications.
The LAN8650/1 MAC-PHYs are supported with a set of network analysis tools, the LAN8651 SPI evaluation board and MPLAB Harmony 3. The MAC-PHYs are available to purchase now.
