New Products system cost. The Flexis AC family extends the benefits of 8-bit to 32-bit compatibility into markets where developers need to optimize their designs to address an array of performance requirements and product price points. The Flexis AC family is an optimal choice for a single-chip motor control/ human-machine interface solution in major appliance applications, but it is also scalable and flexible enough to meet the needs of HVAC systems and building controls.

Cable-based measurements of commercial frequency converters showed that the EN 55011 limits were observed for class A up to 300 m and class B up to 200 m, as well as for class C2 up to 300 m and class C1 up to 200 m as specified by EN 61800-3. The filters of the B84143D*R127 series are designed for currents from 16 A to 200 A at a rated voltage of 520 V. Their high rated temperature of 50 DegC also makes them well suited for fitting in switching cabinets, and the book-style housing allows the filters to be incorporated in limited space conditions.

SENSIRION Miniature liquid flow sensors using planar microfluidic substrates enables highly sensitive thermal flow sensor microchips to measure non-invasively through the wall of a flow channel inside a microfluidic substrate. This design provides unique sensitivity for liquid flow measurement and bubble detection in the microliter range. A small digital CMOSens microchip (2.2 mm x 3.5 mm) is bonded to the microfluidic channel substrate. The component also houses the complete digital intelligence as well as the memory necessary for signal linearization, temperature compensation and self-test algorithms. The sensor boasts a short flow sensing response time of around 30 ms, and sensor resolutions down to 0.5 nl/min are feasible. Customized OEM solutions based on this technology will be developed for high-volume applications.

It offers very low power consumption to extend battery life, and provides more on-chip integration to help reduce the size and cost of battery-driven and sensor-enabled systems such as fire and security alarms, meters, industrial sensors, anti-shake digital cameras, handheld medical diagnostics devices, and data-logging and point-of-sale terminals. The MCUs also deliver high-performance on-chip oscillators, built-in circuits for sensor functions and extended system operating time.

It can control up to 16 individual touch keys with a slider comprising between 2 and 8 of the touch key channels. In addition, the chip can also control up to 11 LEDs through a PWM output function that is controlled by the host, eliminating the need for an external LED controller. This combination of functions makes the device ideal for use as a multimedia human-machine interfacecontroller in mobile phones and consumer applications, such as personal media players, where it saves space, minimizes design time, and allows the designer creative flexibility in laying out control keys. With its wide voltage range (1.8V to 5.5V DC) and low power requirements, it is well suited for other battery-driven applications, such as digital still cameras, PDA’s or handheld gaming devices. < For more information, email: qprox.sales@atmel.com FREESCALE SEMICONDUCTOR The Flexis AC family of microcontrollers features 8-bit devices and 32-bit V1 ColdFire MCUs designed to provide exceptional EMC/EMI performance, precise motor control capabilities, and an array of on-chip peripherals to help reduce component count, system complexity, and overall EPCOS A high-performance series of three-line EMC filters for frequency converters are distinguished by outstanding attenuation 38 applianceDESIGN August 2008 www.applianceDESIGN.com http://www.freescale.com http://www.am.necel.com http://www.appliancedesign.com
