If you need to connect simple devices to a computer, like relays, switches, keypad, or a small display, IO-Warrior56 is a simple solution.
Working with USB used to mean that you had to develop specific code for a USB-enabled microcontroller, developing a unique driver with lots of documentation, using expensive development systems.
IO-Warrior56 also supports a range of industrial standard interfaces such as I2C and SPI to simplify interfacing to chips, circcuits, or displays.
A 4 x 3 bump array with 0. This ADC minimizes both external com- ponent count and total solution size, only requiring a 0. Combining a compact footprint with best- in-class power dissipation 18 microwatts at 1 ms conversion timesthe MAX1 1 is well suited for applications ranging from energy-harvesting 0101, to portable con- sumer electronics, to point-of-load moni- toring voltage, current, and temperature in networking and computer systems.
The MAX1 1 is capable of sample rates up to 94 circkits — 28x faster than the nearest competitor in a comparable solution size. This capability allows the device to spend more time in shutdown mode, further reducing total system power consumption. The MAX1 1 operates from a single 2. For applications that require less than 1 2-bit resolution, the MAX1 is a pin-com- patible 1 0-bit version elektoor the MAX1 1 Production quantities are available now.
This removes an important obstacle to commer- cial viability, allowing end users to enjoy all the benefits of LED lighting with substan- tially lower deployment costs. To facilitate adoption, LED retrofit lamps must be compatible with electronic trans- formers and cut-angle dimmers. Ben rounds out the episode with a complete overhaul of an old, non-working LCD screen and turns it into a perfectly function- ing monitor. LED drivers, however, are very nonlinear and not purely resistive loads.
As a consequence, LED lamps flicker, do not dim, and in some cases do not turn on at all when used with the existing electri- cal infrastructure.
The MAXI solves this problem by using a unique, patent-pending approach to control the input current of the lamp. By actively shaping the input current it ensures flicker-free operation with most electronic transformers and dimmers. This ena- bles LED lamp designers to create drop-in replacements for halogen MR1 6s, thus elim- inating the costly infrastructural upgrades required by competitive solutions.
In addition, the MAXI can be designed in without electrolytic capacitors. This extends the lifetime of the LED lamp, since electrolytic capacitors are usually the first component that fails in the driver circuit.
Operation without electrolytic capaci- tors reduces the cost and size of the driver, allowing it to fit in the small MR1 6 form factor.
A complete GPS receiver requires only antenna and power supply to work. Its exceptionally low cascaded RF section noise figure of 1. Dedicated signal parameter search engine capable of performing 8 mil- lion time-frequency hypothesis testing per second offers fastest signal acquisition per- formance in the industry.
Programmable control parameters include output voltage, mar- gining and current limits, input and output supervisory limits, power-up sequencing and tracking, switching frequency and iden- tification and traceability data.
On-chip pre- cision data converters and EEPROM allow for the capture and nonvolatile storage of regulator configuration settings and telem- etry variables, including input and output voltages and currents, duty cycle, tempera- ture and fault logging.
Up to 6 phases can be interleaved and paralleled for accurate shar- ing among multiple ICs, minimizing input -L “X” w Hi— Vniunci’ l. An integrated amplifier provides true differential remote output voltage sensing, enabling high accuracy regulation, inde- pendent of board IR voltage drops.
By delivering sub 1 2. The nRF is also the first fully qualified Bluetooth v4. The nRF chip makes it as straightforward as possible for designers to add Bluetooth low energy wireless connectivity to existing applications by integrating a com- plete Bluetooth v4. The nRF chip also integrates a unique low toler- ance 32 kHz RC oscillator that eliminates the need for external 32 kHz crystals, a 16 MHz crystal oscillator supporting low cost 16 MHz crystals, plus an on-chip lin- ear voltage regulator that provides a supply range of 1.
Production samples and a development kit for the pBlue nRF are available now directly from Nordic Semiconductor.

White lighting and magnifica- tion products, Kimco is offering a special savings on the LV Micro-Lite. Twelve LEDs provide light output approaching fiber optic units and a life span that is claimed to be unrivaled by any other illuminator. Default settings can be optionally configured by external resistor dividers for output volt- age, switching freguency, phase and device address.
Multiple designs can be easily cali- brated and configured in firmware to opti- mize a single hardware design for a range of applications. The converter loop gain does not change as the power supply parameters are modified, so compensation remains opti- mized for multiple configurations.
Highest efficiency is achieved by sensing the voltage drop across the out- put inductor DCR to sense current, or an external sense resistor can optionally be used. Programmable DCR temperature compensation cancels the TC of the copper inductor to maintain an accurate and con- stant current limit over a broad tempera- ture range.
Accurate circuita across multiple chips and event-based sequenc- ing allow the optimization of power-up and power-down of complex, multiple rail sys- tems. Additional features include constant frequency current mode control with cycle- by-cycle current limit, adjustable soft start, a synchronizable switching frequency, and programmable GPIO pins to indicate part status and to provide autonomous recov- elekyor from faults.
Additionally, design enhancements also provide lower power consumption of 0. By main- taining common pin-outs, the PIC32 portfolio also provides designers with the optimum balance of memory and cost for their high-performance appli- cations as well as a seamless migration path for scalability and flexibility. The latest 80 MHz PIC32 micro- controller family helps embed- ded designers to lower their costs without sacrificing per- formance or functionality. Each of the six new microcontrollers is available in five different pin-compatible packages: Medical devices and Security: As a slave it runs under another microcontroller or PC or it can operate in auto-run master mode which allows the elektod to add a few switches and run the stepper motor manu- ally.
It allows eight RPM selec- tions in free running mode and is compat- ible with the L, L drivers as well as discrete transistors.
