| | Fastest H8SX 32-bit microcontroller to date offers USB module and six
serial ports | | London – Renesas Technology Europe announced the H8SX/1653F, the fastest
member to date of the high performance H8SX family of 32-bit microcontrollers. The device offers 50 Dhrystone MIPS
performance at 3.3V/50MHz and is supported by 384 Kbyte of full speed, zero-wait embedded Flash and 40 Kbyte RAM. It
also boasts a USB slave module and six serial ports, which amongst them support async, sync, ISO7816 and IrDA modes
as well as two channels of I2C. The H8SX/1653F is ideal for electronic point of sales (EPOS) applications, the
latest generation of health monitoring and fitness gadgets, and for building/industrial automation. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 06:03 | |
| | | LTC3783: High Power LED Driver with 3000:1 PWM Dimming Range Delivers
True Color | | MILPITAS, CA – Linear Technology Corporation introduces the LTC3783, a
current-mode multi-topology converter with constant-current PWM, dimming for driving high-power LED strings and
clusters. Proprietary techniques provide extremely fast, true PWM load switching with no transient undervoltage or
overvoltage issues. Ratios of 3000:1 can be achieved digitally as True Color PWMä dimming guarantees color integrity
of white and RGB LEDs. The LTC3783 allows an additional 100:1 dimming ratio using analog control. This versatile
controller can be used as a boost, buck, buck-boost, SEPIC, or flyback converter, and as a
constant-current/constant-voltage regulator. No RSENSE™ operation uses the on-resistance of a MOSFET to eliminate
the current-sense resistor, increasing efficiency. Applications for the LTC3783 include high-voltage LED arrays and
backlighting, as well as voltage regulators in telecom, automotive and industrial control systems. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 05:58 | |

| | | American Bright Introduces High-Intensity 3- and 4-Watt LED Modules
To Offer Cost-Effective, | | Chino, CA - American Bright Optoelectronics has announced a
breakthrough in power LED capabilities, with its new NovaBriteTM 3-Watt LED unit packaging, offering one of the
industry's highest powered devices, capable of displaying 6500K (IF = 350mA) with an input power of 3.0 Watts (PD)
in standard colors, and a uniquely brighter white, 120-lumen unit capable of handling up to 4.0 Watts. Immediate
cost-savings can be realized with the use of this type of single lens, high-power LED as a simple, more reliable
alternative to incandescant lighting, and a contender for replacement of higher cost, higher temperature lighting
such as Metal Halide. Applications include safety lighting, crossing gate and warning lighting, taillights, light
torches, desk lamps, flashlights, and large-screen LCD backlighting, interior lighting for automotive, architectural
lighting, and other space-conscious applications. It is also considered a high-intensity light source for general
lighting needs requiring a high intensity, long-life light source, and where thermal management is a key
design/function criterion. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 05:49 | |

| Vitesse Introduces Grooming Switches That Enable Lowest Cost,
Next-generation Access and Metro Equipment | | CAMARILLO, Calif. - Vitesse Semiconductor
Corp. announced two new additions to its industry-leading SONET/SDH Time Slot Interchange (TSI) grooming switch
family: the VSC9190, 50 Gbps TSI Switch, and the VSC9191, 100 Gbps TSI Switch. Both devices are targeted at
dramatically reducing power and complexity of SONET grooming applications, while simultaneously simplifying and
accelerating the system level design process. These devices reduce power requirements by more than 50% over
comparable solutions, and, by incorporating automatic protection switching and rate aggregation into a single
device, reduce board chip count by a factor of five, dramatically shrinking space requirements and lowering costs. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 05:43 | |
