NFC transponder hardware simplifies Bluetooth and Wi-Fi pairing Texas Instruments’ Dynamic NFC Transponder RF430CL330H hardware enables uncomplicated and inexpensive wireless set up. The low cost kit brings a secure, simplified pairing process for Bluetooth and Wi-Fi connections to products, such as printers, speakers, headsets, and remote controls, as well as computer peripherals. Designed specifically for NFC connection handover and service Interface functions, the kit includes host diagnostics and software upgrades. The company also announced its NFCLink software firmware library, developed in partnership with Stollman E+V GmbH and Kronegger GmbH to streamlining NFC development across TI’s entire embedded processing portfolio. The Dynamic NFC Transponder RF430CL330H combines a wireless NFC Interface and wired SPI/I2C Interface to connect the device to a host (classified as an NFC tag type 4 device). The data content is then shifted dynamically from the host into the RF430CL330H’s SRAM and can then be transferred over the NFC interface. The transponder supports data rates up to 848 KBs per second for RF data transfer (over-the-air firmware updates). It incorporates an ISO 14443B-compliant RF interface, allowing wireless access of NDEF messages. The host wakeup capability in an RF field maximizes battery life. Texas Instruments www.ti.com Quad-core HSPA+ processor with 5G WiFi, NFC, GPS and indoor positioning Broadcom Corporation has announced a quad-core HSPA+ processor designed for high-performance, entry-level smartphones. The BCM23550 is the company’s latest smartphone platform optimized for the Android 4.2 Jelly Bean operating system (OS). According to research firm International Data Corporation (IDC), the first quarter of 2013 marked the first time that smartphones comprised more than half of all phones shipped globally. This growth is driven by mass market consumers who demand affordable devices that deliver increased functionality and a level of performance that was previously available only in higher-end superphones. The BCM23550, and its turnkey design, are powered by a quad-core processor running at 1.2 GHz, VideoCore multimedia and an integrated HSPA+ cellular baseband that provides enhanced, powerefficient features for entry-level smartphones. The BCM23550 supports “dual HD,” allowing users to simultaneously share high-definition content from a small handheld screen to a larger, Miracast-enabled display. It includes leading VideoCore technology for fluid, responsive graphics and incorporates Power Management techniques to optimize battery life and reduce power consumption without compromising the user experience. The platform provides an integrated Image Signal Processor (ISP) that supports up to 12-megapixel Sensors with advanced imaging capabilities such as blink and smile detection, face tracking, red eye reduction, fast shot to shot (burst capture), zero shutter lag, and best picture selection. Broadcom Corporation www.broadcom.com 3.5x3.55mm SMT side actuated switch takes up to 100,000 cycles The new SMT side actuated switch series developed by C&K components increases operating life while reducing the footprint. The PTS 840 Series switch is available with front PIP leads that deliver strong shear resistance and higher reliability than other technologies. Combining small size, an extended life span of up to 100,000 cycles, and an optional ESD pin, the robust PTS 840 Series switch is suitable for inclusion in a variety of systems where PCB space is limited, including nomad devices, remote controls, personal health diagnostic systems, and consumer electronics applications. The SMT side actuated switch measures a slim 3.5x3.55mm with a travel path of 0.2mm + 0.2mm / -0.1mm. The momentary action of PTS 840 Series switch with J-, G-, and front PIP-type terminals can withstand contact resistances of under 500mohms and insulation resistances of over 100mohms. Through the use of two-shot moulding, paint and laser etch, pad printing, and plating processes, the switches are designed to stand out. The PTS 840 Series switches exhibit a bounce time of less than 10ms and an operating temperature of -40ºC to 85ºC. C&K Components www.ck-components.com 12.7mm diameter slotless brushless DC motor delivers up to 0.0064Nm The BI-05 Series slotless brushless DC motor was designed by Pittman Motors for maximum precision and performance in a package size perfectly suited for precision equipment such as surgical and dental tools. The BI-05 was developed with stringent design criteria as the focal point. Its slotless motor design eliminates the magnetic cogging typically found in conventionally wound “slotted” brushless DC motors. The stator teeth are completely eliminated by forming and encapsulating the entire stator winding along the inside surface of the back iron. The result is zero detent torque, low inductance and extremely fast response rates. The BI-05 motor body has a 12.7mm diameter and is capable of no-load speeds of up to 60,000 RPM. The miniature motor is rated for a continuous output torque rating of up to 0.0064Nm. The overall motor construction is a combination of 17-4, 300, and 400 series stainless steels, the 4-pole rotor is built using high-energy neodymium magnets, and an internal circuit board supports hall sensor feedback spaced at 120 electrical degrees. Other standard features include shielded ball bearings and a tight rotor balancing spec for smooth and quiet operation at high speeds. An autoclavable version of the BI-05 also is available.
