Posted on by mixos

PrizmaCap™ is a superlative new series of standard and custom supercapacitors that employ a revolutionary new design in terms of form, fit, and function compared with other supercapacitors from Kyocera AVX. Leveraging this innovation, the supercapacitors have been engineered to provide peak performance in an array of Size, Weight and Power (SWaP) optimized, battery-powered products.

The PrizmaCap supercapacitors can be used on their own as system power backup devices, replacing batteries in some cases, or they can be used in conjunction with primary or secondary batteries. Using them in conjunction with a battery allows for extended system backup time, improved battery life, and allows provision of instantaneous power pulses in energy storage, energy and power holdup, pulse power handling, and battery assist applications.

Key Features

Data

How does PrizmaCap improve battery performance?

Essentially, the addition of a PrizmaCap helps smooth out the power demand which in turn enhances the performance and lifetime of the battery. Instantaneous power pulses, such as those typically seen in wireless communication systems during transmit cycles, or peak power assist requirements, such as those in motor drives, put a lot of current strain on the battery during these discharge events. Repetitive or prolonged exposure to power pulses and peak power assists leads to increased battery heating, shorter run times and will ultimately impact the effective life of the battery by reducing its number of overall charge/discharge cycles. Placing a supercapacitor in parallel with the battery effectively buffers it from the harmful effects of these repetitive power pulses, thus supplementing the performance and lifetime of the battery.

The PrizmaCap has an inherent low ESR which allows it to deliver large peak currents, up to 8.63A on the 15F model, and they are capable of fast charge/discharge cycles. Furthermore, their number of charge/discharge cycles far exceeds that of battery technology with more than 500K cycles achievable under specified conditions.

These attributes make it possible for designers to increase the lifetime of the battery in a system, achieve longer run times and reduce servicing costs throughout the life cycle of the end product. Alternatively, it is also possible to specify smaller capacity batteries when using them in conjunction with supercapacitors, because any peak current demands are supplemented by the supercapacitor allowing a battery with a lower maximum discharge pulse current to be used.

Technical Description of PrizmaCap

The SCP Series PrizmaCap is initially offered in three standard capacitances with higher capacitance values and rated voltages planned for release in the coming months. The three capacitances offered today are 3.5F, 8.5F and 15F with a rated voltage of 2.1V (derating to 1.1V for +90°C operation) and energy densities 1.14, 1.87 and 2.43Wh/kg respectively. They are also rated for maximum DCL as low as 50μA after 72 hours of operation, maximum ESR as low as 30mΩ at 1kHz and 55mΩ at DC, and up to 2,582W/kg power density and 0.0092Wh maximum energy. PrizmaCap offers the highest capacitance and energy densities currently available in the market for any small form factor (SFF) prismatic supercapacitors rated at more than 1F.

Additional off-the-shelf solutions with standard footprints and capacitance values are planned and will be released as they are qualified. Custom SCP Series PrizmaCap supercapacitors are possible with customer-specified footprints and capacitance values spanning 1–500F.

The wide applicability of PrizmaCap

PrizmaCap supercapacitors are suitable for a wide range of application uses including but not limited to wearables, handheld devices, high temp industrial equipment, Bluetooth keyboards, battery assist for power tools and communication devices, medical devices, power peripherals, Tablet/E-Reader, Military and high reliability equipment and space constrained designs.

They feature a wide operating temperature range specified from -55°C to +90°C with appropriate derating, this is the widest available from any supercapacitor currently available on the market and allows PrizmaCap to be used in applications that were previously off limits to this technology.

The PrizmaCap supercapacitors are based on a propylene carbonate electrolyte technology, which has been proven safe and effective in energy storage applications including lithium-ion batteries, this technology also allows the products to be extremely lightweight (<2gm) and the prismatic form factor allows for a very low-profile from 0.8 to 2mm.

Measuring just 48 x 45mm with maximum thickness of 2mm, the compact size of the PrizmaCap makes them especially well-suited for use in energy harvesting, wearable & handheld devices, energy metering, industrial equipment, consumer devices and any other application using high density PCB’s. The supercapacitors have two fixed-position, surface-mount terminals which are compatible with hand soldering, or for more reliable and production friendly connections they can be terminated using Kyocera AVX Interconnect’s economical and ultralow-profile 70-9159 Series STRIPT™ two-piece, single contacts.

The SCP Series PrizmaCap supercapacitors are RoHS- and REACH-compliant, lead-free compatible, and currently made in the USA. To ensure optimal performance and quality, Kyocera AVX have qualified the supercapacitors for life cycle, high-temperature load life, temperature characteristics, vibration resistance, and humidity characteristics.

EyeCloud’s OpenNCC Neural Compute Board will be a Drop-in Open-Source Replacement for Intel’s Neural Compute Stick 2 In Edge-AI Applications

Posted on by Emmanuel Odunlade

Edge AI specialist, EyeCloud.AI, is getting set to launch a new OpenNCC Neural Compute Board (NCB) that will act as an open-source alternative to Intel’s Neural Compute Stick 2 (NCS2) in edge AI and computer vision projects.

The accelerated AI reference platform will support on-board inference AI models and work well with Raspberry Pi boards as well as other Arm Linux SoCs. Speaking on the design of the upcoming board and how it is expected to function, particularly on how it completely replaces the Intel Neural Compute Stick 2,  EyeCloud explained that the OpenNCC NCB has the same functionality as the Intel NCS2 with a host machine.

“The Host App on the Host Machine obtains the video stream (local file, IPC, webcam, or V4L2 MIPI cam, for example) from the outside, configures the preprocessing module according to the resolution and format of the input file of the reasoning model, then sends the visual stream to the OpenNCC NCB through the OpenNCC Native SDK for reasoning and returns the reasoning results. The reasoning supports asynchronous and synchronous models, the reasoning pipeline on OpenNCC SoM is configured through OpenNCC model JSON.”

The only difference there probably is between the OpenNCC NCB board and the Intel NCS2 is just that the former is offered as an open-source design and comes in two variants: an FPC version or a USB Type-C version which will support USB 3.0 speeds.

The compact accelerator board has at its heart, Intel’s most advanced VPU, the Movidius Myriad X VPU programmable with the Intel Distribution of the OpenVINO toolkit for porting neural networks to the edge. The VPU is the first of its kind to come with the Neural Compute Engine – a dedicated hardware accelerator for deep neural network inferences. The Neural Compute Engine works hand in hand with 16 SHAVE cores and an ultra-high throughput intelligent memory fabric to make the VPU the industry leader for on-device deep neural networks and computer vision projects. Other upgrades that have equally come with the VPU in recent times include upgraded and expanded vision accelerators, a new native 4K ISP pipeline with support for up to 8 HD sensors directly connected to the VPU.

Other board specifications will Include:

  • VPU: Intel Movidius Myriad X MV2085
  • 16 SHAVEs Vector processors
  • 20+ Vision Accelerators
  • 2x Neural Compute Engines (up to 4TOPS)
  • 8 GB, LPDDR4 (1600 MHz, 32-bit)
  • USB 3.0/USB 2.0 with USB Type-C or USB 2.0 with FPC
  • Power Supply: 5V/2A
  • Dimensions: 38 mm x 38 mm (1.5 inches by 1.5 inches)
  • Weight: 9 grams
  • Compatible with Intel’s Distribution of OpenVINO (Version 2020.3, 2021.4)

The OpenNCC NCB will also be able to support up to 6-way reasoning pipeline configuration locally and can execute a 2-way pipeline simultaneously in real-time. It can also work with multiples of itself and the SDK can dynamically allocate computing power if you wish to expand the number of NCB to suit your computing power needs.

OpenNCC NCB will be open hardware, but only hardware board schematics and open software in the form of OpenVINO and OpenNCC Frame have been published for now. The board will soon launch on CrowdSupply, so you can sign up to get notified when the campaign finally goes live as well as to get useful updates about the project.

Voice Echo Processor Module – Delay Device for Sound Effects, Echo, Reverb 

The voice echo or digital delay sound effects project presented here is suitable for applications such as Karaoke, multimedia, musical instrument effects, electronics toys, animatronics, etc. The project is based on PT2399 chip, with an operating supply of 5V DC, and approx. 30mA current consumption. Two potentiometers are provided to set the delay and repeat. The delay range is adjustable from 50ms to 280ms.

The PT2399 is a single-chip echo processor IC utilizing CMOS technology. It accepts analog audio input signal, and a high sample rate ADC converts the analog signal into a bit stream that is stored in internal 44Kbit RAM. After processing the bit stream it will be de-modulated by DAC and lowpass filter. The overall delay time is determined by the internal VCO clock frequency, and the user can easily change the VCO frequency by changing the external resistance. The PT2399 performs low distortion (THD<0.5%@0.5Vrms) and low noise (No<-90dBV) characteristics for audio purposes.

Note1: With this board, the delay range is 50ms to 280ms which is adjustable using the potentiometer. The actual delay range is 31.3ms to 342ms, to achieve this alter the value of resistor R9 and Trimmer potentiometer PR2.

Note2: The PCB has provision to mount Trimmer pot or 16MM potentiometer, install any of this as per requirement, PR1 Trimmer Pot = P1 16MM potentiometer, PR2 Trimmer Pot = P2 16MM potentiometer.

Ultra-High-Speed, Low-Distortion – Differential-to-Single-Ended Line Receivers with Enable

The project presented here is a differential line receiver that offers unparalleled high-speed, low-distortion performance and is ideally suited for digital, video, and RF signal-processing applications. These receivers offer a small-signal bandwidth of 550MHz and have a high slew rate of up to 2000-3800V/µs. The board’s 120mA output capability allows it to be directly coupled to data acquisition systems. The project has been designed using the MAX4445 chip, which has a three-op amp instrumentation amplifier architecture. These ICs have symmetrical differential inputs and a single-ended output. The project operates from ±5V supply and is capable of driving a 100Ω load to ±3.7V.  MAX4445 is compensated for gains of +2V/V or greater, set by an external resistor R3. A low-power enable mode reduces current consumption to 3.5mA. Using current-feedback techniques, the MAX4445 achieves a 550MHz bandwidth while maintaining up to a 5000V/µs slew rate. Excellent differential gain/phase and noise specifications make these amplifiers ideal for a wide variety of digital, video, and RF signal-processing applications. It is important to make a Gold-plated high-quality PCB and use high-grade components and connectors to operate at high frequency.

The project is compatible and can be paired with our Wideband, High-Output-Current – Single Ended-to-Differential Line Drivers with Enable that has been published in past.

Low-Power Enable Mode

The chip is disabled when Enable pin goes low. This reduces the supply current to only 3.5mA. In this case, the output becomes high impedance.  The effective output impedance for the MAX4445 is 1.8kΩ plus RGAIN (Resistor R3)

Setting Gain (Resistor R3) – Default Gain +2V/V

The MAX4445 is stable with a minimum gain configuration of +2V/V. RGAIN R3, connected between the RG pins. Gain can be changed using the below formula:

Gain = (1 + 600 / RGAIN)

Coaxial Line Driver

The project is well suited to drive coaxial cables. The high output current capability can easily drive the 75Ω characteristic impedance of common coaxial cables. Adjust the gain of the MAX4445 to compensate for cable losses to maintain the required levels at the input of the next stage.
