SAN JOSE, Calif. -- Cypress Semiconductor Corp. (Nasdaq: CY) today introduced a new PSoC® programmable system-on-chip that simplifies the design of next-generation industrial, home appliance and consumer systems that require multiple sensors. Many Internet of Things (IoT) applications require multiple sensors and can benefit from dedicated coprocessors that offload sensor processing from the host and reduce overall system power consumption. The new PSoC Analog Coprocessor integrates programmable analog blocks, including a new Universal Analog Block (UAB), which can be configured with GUI-based software components. This combination simplifies the design of custom analog front ends for sensor interfaces by allowing engineers to update sensor features quickly with no hardware or host processor software changes, while also reducing BOM costs.

For example, in home automation applications, engineers can easily configure the PSoC Analog Coprocessor to continuously monitor multiple sensors, such as temperature, humidity, ambient light, motion and sound, allowing the host to stay in a standby low-power mode. Future design changes to support new sensor types can also be easily implemented by reconfiguring the programmable analog blocks. Cypress will demonstrate the PSoC Analog Coprocessor, along with its PSoC, FM Flexible MCU, Bluetooth® Low Energy and Energy Harvesting Power Management IC solutions at Sensors Expo from June 21 to 23 in booth 416 at the McEnery Convention Center in San Jose. More information on the PSoC Analog Coprocessor is available at www.cypress.com/PSoCAnalog.[Continue reading →]

Microchip\'s new MCP3919 and MCP3912 AFEs integrate three and four channels of 24-bit, delta-sigma Analog-to-Digital Conversion (ADC), respectively, with industry-leading accuracy of 93.5 dB SINAD, -107 dB THD and 112 dB SFDR for precise signal acquisition and higher-performing end products. AFE completes Microchip’s MCP391X family, which spans 1 to 8-channel members for single-phase and poly-phase energy measurement. CHANDLER, Ariz. — Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced the completion of its high-accuracy, 1-8 channel, single and poly-phase MCP391X energy-measurement Analog Front End (AFE) family. The new MCP3919 and MCP3912 members integrate three and four channels of 24-bit, delta-sigma Analog-to-Digital Conversion (ADC), respectively, with industry-leading accuracy of 93.5 dB SINAD, -107 dB THD and 112 dB SFDR for precise signal acquisition and higher-performing end products. These are the optimal numbers of channels for single-phase energy meters with neutral monitoring (3-channel); or single-phase, three-wire energy meters (4-channel). The high level of integration on the new AFEs also includes a low-drift voltage reference, programmable gain amplifiers, phase-delay compensation and cyclic redundancy check (CRC).

As the energy-metering infrastructure is being upgraded worldwide, designers are demanding increased AFE accuracy and integration to develop the latest generation of smart meters. These features are also required by the designers of advanced power-monitoring systems for applications such as server power supplies and power distribution units, electronic circuit breakers, smart power strips and other data-acquisition products in the industrial, commercial and consumer markets. Microchip’s newest AFEs improve application performance with their industry-leading accuracy, high integration and optimal number of channels for single-phase energy measurement. Additionally, the high AFE accuracy facilitates energy-meter calibration, which reduces production costs.[Continue reading →]

PC/104 Sized Microcontroller with PIC32 Micro/sys recently released a low-power single board microcontroller with fully integrated web hosting, networking, and analog I/O on a PC/104 form factor (3.775” x 3.55”). Featuring Microchip’s 80MHz PIC32® microcontroller, the USB3032 is an ideal COTS solution for applications requiring low power in -40˚C to +85˚C operation. USB3032 includes access to Microchip’s easy-to-use and widely supported IDE tool suite and protocol stacks, which, combined with Micro/sys’ 10-year product availability and attractive OEM pricing, allows designers to shorten time-to-market and maximize development productivity while keeping overall system production and maintenance costs low.

With this simple microcontroller, designers can communicate via different communication protocols while their production, security monitoring, data logging, or test and measurement control application continues running. Some mix-and-match protocol conversions available are Ethernet to CAN, CAN to USB, and USB to RS232. For example, a user might want the USB3032 to communicate via 10/100 Mbps Ethernet to an internal IT intranet to transmit instructions for controlling the on-board D/A, A/D or I/O in the field, then forward the results via CAN down-stream to other processes for control. USB3032 performs well in such environments by storing up to 1024 messages in 32 buffers while offering user-selectable filter-to-buffer mapping with 32 filters and 4 filter masks. For maximum data processing over Ethernet and CAN, USB3032 offers a built-in DMA interface.[Continue reading →]

White Paper

This White Paper describes the implementation of the Rohde & Schwarz (R&S) FSVR’s realtime capabilities. It shows fields of application as well as the technical implementation. The measurement speed available in today's spectrum analyzers is the result of a long evolution. But one property has survived all evolution steps: even the R&S FSV does not detect signals between the end of one sweep and the start of the next one. This gap in data acquisition, the so called "blind time", has decreased with each new spectrum analyzer generation, but it is still present.

The keys to a real-time spectrum analyzer are: · Parallel sampling and FFT calculation: The data acquisition continues while the FFTs are performed. · Fast processing of FFT algorithms: The computation speed must be high enough to avoid that "stacks" of unprocessed data are being built up. Slow FFT computation will result in an overflow of the capture memory and a subsequent data loss (= a new blind time).[Continue reading →]

The 23rd annual Hot Chips conference at Stanford University held a series of talks that were billed as a "tutorial" on Package-Scale Power Management. In actuality, the talks were less tutorial and more of a review of the challenges, and current and (potential) future solutions for power management in heterogeneous multicore designs. One common thread that ran through each of the presentations... integration of more complex and higher performance analog circuits is an absolute requirement. Digital needs analog more than ever.

Daniel explains why wireless and medical imaging systems cannot simply appropriate data compression technologies, such as MP3, used in other fields, elaborating on why compression technologies fall short for higher-performance applications. He then describes a new compression algorithm that can keep pace with sample rates of up to 40 gigasamples per second.Today’s Data Acquisition Systems (DAS) using Analog-to-Digital Converters (ADCs) in wireless infrastructure and medical imaging applications are adding more channels while at the same time increasing both bit-resolutions and sampling rates, causing a data explosion at the system level. All this data must be transported from the DAS, where it is acquired, to processing devices such as FPGAs or CPUs, where the raw data is processed. This “data pipe” uses many device I/Os, crosses various interfaces and busses, and often includes different forms of storage along the way such as DRAM or disk drives and RAID. Over the years, the brute force approach to increasing the size and capacity of this pipe was to throw more hardware at the problem. Indeed, ADCs grew wider in bits; FPGAs grew larger in density, and memory requirements increased accordingly, with the same thing happening to a lesser extent in I/O as well. Systems grew more complex, used more power, and saw overall higher bill of material costs.

Dealing with this data explosion without increasing complexity and cost in FPGA-based designs means adopting some form of data compression in the FPGA, usually with IP algorithms. Real-time signal compression of the data sampled in systems such as wireless and medical imaging can take on the data geyser, at the same time reducing system complexity, power, and costs.[Continue reading →]
