Intersil, Renesas offer RL78-based sensor conditioning circuit

Intersil has joined with Renesas Electronics to develop a sensor signal conditioning reference design for thermocouple, pressure and strain gauges. The design incorporates two boards - an Intersil board with analogue front-end chips and a Renesas RL78/G13 microcontroller development board. Renesas ups analogue spec of MCU for sensor apps The analogue-to-digital front-end incorporates the ISL28617 40V instrumentation amplifier with integrated ADC driver, the ISL28134 5V zero drift op amp, the ISL26102 24-bit delta sigma converter and the ISL21090, an ultra low noise precision bandgap voltage reference, among others. Software interface is included for evaluation purposes. Powered by USB It is powered from more

AMD R-series processor adds 3D graphics to video walls

When we look at a video wall system it is interesting to look at what lies behind the display screens — both literally and figuratively. As a rule, video wall systems display high-quality videos and 3D graphics, and require a maximum number of graphics connections. A reference board from Congatec offers the necessary interfaces in combination with an MXM graphics module and a COM Express CPU module, which is based on the latest COM Express specification 2.1 for Pin-out Type 6. Three panels are addressed via the computer module, a further six via the MXM graphics unit. Displays can also be connected via more

Debugger for Altera FPGAs with ARM cores

Altera and ARM have developed a development tool for debugging Altera FPGAs which contain hard ARM cores. It will be included in the Altera SoC Embedded Design suite due early next year. “It’s a unique collaboration between ARM and Altera to overcome the challenges of debugging complex SOC,” says ARM vp John Cornish. The tool is for 28nm Cyclone V and Arria V and for upcoming 20nm Altera/ARM parts. “We have over a dozen customer committs for this product,” says Altera vp Chris Balough, “all the discussions are done and the price negotiations completed.” The price is a “shockingly good price point”, says more

Linear power chip has eight regulated channels

Linear Technology’s latest power management IC for low voltage power supplies has eight independent 1A channels with I2C control, sequencing and fault monitoring in a QFN package. Each channel has a synchronous step-down regulator with independent 2.25V to 5.5V input supply and an output voltage range of 0.425V to VIN.   The chip’s buck DC/DCs may be connected in parallel to achieve higher output currents up to 4A per output with a single shared inductor. Up to four adjacent regulators can be combined, resulting in 15 different possible output configurations.   All of the switching regulators are internally compensated and need only external feedback resistors to more

Atmel adds motion sensor to touch controller

  Atmel has introduced a range of touch controllers that integrate motion sensor functionality. The maXTouch controllers incorporate the company's maXFusion sensor technology which combines inputs from multiple sensors that detect motion, including accelerometers, magnetometers and gyroscopes, to provide real-time direction, orientation and inclination data.Atmel said the controller can be used with pre-qualified sensors from various manufacturers, including AKM, Aichi Steel, Bosch, InvenSense, Intersil and Kionix. The UC3L sensor hub devices are available with customisable firmware.

TI adds gain control to differential amplifier

Texas Instruments has introduced its first differential amplifiers which are programmable for variable gain. The 2.4GHz LMH6881 single-channel and 2.4GHz LMH6882 dual-channel amplifiers have a 6dB to 26dB gain range.  "The programmable gain control in the LMH6881 and LMH6882 eliminates the need for gain-setting resistors and their associated mismatch errors, enabling more robust systems for applications, such as medical, test and measurement, military, wireless communications, and microwave backhaul," said the supplier. Noise figures at maximum gain (26dB) and 100MHz input frequency are: 9.7dB noise figure, 44-dBm OIP3, and -100 dBc HD3. Gain control can be implemented via SPI bus or dedicated pins, with no external resistors needed. The devices support  DC/AC coupling more

Microchip’s crystal-free USB 2.0 microcontroller

Microchip has added to its range of certified Full-Speed USB 2.0 device PIC microcontrollers portfolio 15 scalable 8-bit MCUs ranging from 14 to 100 pins with up to 128kbyte of flash. The MCUs have internal clock sources with the 0.25% clock accuracy necessary for USB communication, and so eliminate the need and cost of an external crystal. All devices offer power consumption down to 35µA/MHz in active mode and 20nA in Sleep mode.  "These crystal-free USB microcontrollers are the first to be offered with pin-counts ranging from 14 to 100 combined with such a high level of integration and low power consumption," said the supplier. more
