Capacitive starter kit accelerates touch-based HMI deployment With its touch sensing starter kit (part# Y-RX113CAPT01), Renesas Electronics is offering extra support for its RX113 Group of 32-bit microcontrollers which incorporate capacitive touch sensor IP. The kit offers systems designers greater flexibility in developing humanmachine interface (HMI) applications for home appliances, industrial machinery, and others that require touch capability in rugged environments. The capacitive touch sensor IP delivers both high sensitivity and high noise tolerance, allowing touch recognition even when the operator is wearing gloves, for instance with industrial applications such as numerical control machine tool control panels. It also provides excellent water resistance, making it suitable for use in a wide variety of product categories, including electric kitchen appliances that may be exposed to water spills, such as induction heating cooking devices or dishwashers, or products designed for wet environments, such as remote controls for bath water heaters or waterresistant TV sets. The kit also provides automatic tuning functionality that solves a key problem for capacitive touch interface development: the trade-off between touch sensitivity and noise tolerance. The starter kit is bundled with four touch sensing evaluation boards, making it simple to create suitable environments for testing panel materials, proximity or position sensing, and more. Renesas Electronics Snap-action switch evaluation kit harvests energy Cheery Industrial Solutions has unveiled a revised Evaluation Kit 2.0 to demonstrate its energy harvesting technology. The kit contains an inductive-based energy harvesting generator, rocker switch and a snap-action switch and provides users with the opportunity to carry out initial application tests. In addition, a compatible receiver with antenna is also included. A detailed manual, drivers and software for the receiver are available for download from Cherry’s website. The Evaluation Kit 2.0 allows users to measure the switching performance, range and signal strength, as well as the environmental influences of the radio transmission in various applications such as building and industrial automation. The addition of a (non-functional) energy harvesting generator means that mechanical design considerations, inclu-ding mounting position etc., can also be simulated. The inductive generator transforms energy created by mechanical actuation into an electrical energy pulse which is then transformed into a constant supply voltage to power the radio electronics. The housed switches and the receiver are available for European and North-American frequency bands (868MHz or 915MHz). A ready-for-installation energy harvesting wireless light switch module for the KNX-RF standard will be available in summer 2015. ZF Friedrichshafen AG Electronic Systems www.zf.com 4 Mbit asynchronous SRAMs www.renesas.eu have on-chip ECCx These 4Mb SRAMs improve data reliability by three orders of magnitude over SRAMs without ECC, while helping to conserve battery life in handheld systems. Cypress Semiconductor’s 4Mb asynchronous SRAMs with ECC can provide the highest levels of data reliability, without the need for additional error correction chips—simplifying designs and reducing board space. The devices ensure data reliability in industrial, military, communication, data processing, medical, consumer and automotive applications. Soft errors caused by background radiation can corrupt memory content, resulting in a loss of critical data. A hardware ECC block in Cypress’s new asynchronous SRAM family performs all error correction functions inline, without user intervention, delivering Soft Error Rate (SER) performance of less than 0.1 FIT/Mb (one FIT is equivalent to one error per billion hours of device operation). The new devices are pin-compatible with current asynchronous fast and low-power SRAMs, enabling you to boost system reliability while retaining board layout. The 4Mb SRAMs also include an optional error indication signal that indicates the correction of single-bit errors. The Cypress 4 Mb asynchronous SRAMs are available in three options—Fast, MoBL and Fast with “PowerSnooze”—an additional power-saving Deep Sleep mode that achieves 15 μA (max) deep-sleep current for the 4 Mb SRAM. Cypress www.cypress.com Vision server supports up to eight individual GigE ports Designed to be used in harsh environments, MPL AG’s Vision Server comes with up to eight individual GigE ports on RJ45 or M12, of which four are available with PoE+. The units integrate Intel mobile CPUs and Intel LAN chips to ensure long time availability (10 years and more) and repair-ability (typically 20 years and more after introduction). The CPU as well as the ECC DDR3 memory chips are soldered on-board, allowing to mount them direct to the housing for the best cooling and to avoid heat pipes. The new PIP30 Family is designed such, that the Fit & Form still remains the same as when the first PIP was introduced in 1996. Inputs are reverse polarity and load dump protected, for a power range from 9 to 36VDC. Galvanic separation can be added internally. Up to four mass storage devices can be integrated that can also be configured as RAID. WLAN or GPS are available as options. A large set of interfaces include up to seven USB (3.0 and 2.0), up to four serial lines (RS232/485), PS/2, external SATA port, and as specialty an external PCI-E or eSATA port. Internally available are two SATA interfaces. What’s more, the unit can easily be expanded over various expansion ports like; up to 6 miniPCIe, PCI-104, PCI/104-Express, or PCI-Express x 16.
