80V DC/DC Converter Makes Positive or Negative Regulated Voltages

MILPITAS, CA – June 9, 2010 – Linear Technology Corporation announces the LT3958, a high input voltage DC/DC converter for boost, flyback, SEPIC and inverting power supply applications. This device operates over an input voltage range from 5V to 80V, has an onboard 84V/3.5A power switch, and can achieve efficiencies up to 96%, making it well suited for industrial, automotive, medical and telecom applications.

The LT3958 is capable of generating either a positive or negative regulated output voltage with its two voltage feedback error amplifiers and reference voltages. One set is for positive output voltages, the other is for negative output voltages, both off a single feedback pin, making the LT3958 highly versatile. With a programmable fixed or synchronizable operating frequency from 100k Hz to 1MHz, designers can choose a wide range of inductors and capacitors to optimize size, performance and cost. Its current-mode control results in stable operation over a wide range of supply and output voltages. The device supports designs using only ceramic capacitors, enabling a smaller solution size. Additional features include programmable soft-start, adjustable input undervoltage lockout, along with output overvoltage and overcurrent protection.

The LT3958 operates from a -40ºC to 125ºC temperature range and is offered in a 5mm x 6mm QFN-36 package with additional pin spacing to support high voltage operation. The1000-piece price starts at $3.05 each. For more information, visit http://www.linear.com/pr/3958.

Menta and LIRMM Launch Manufacturing of World’s First MRAM-based FPGA

MONTPELLIER, France, June 9, 2010 — Menta SAS and LIRMM, an embedded programmable logic provider of embedded-FPGA Intellectual Property (IP) and a joint CNRS and University of Montpellier 2 research laboratory, today confirmed the tape out of world’s first MRAM-based FPGA. The MRAM-based FPGA leverages key innovations including non-volatile magnetic memory and patent-protected circuitry enabling compact integration of MRAM and embedded-FPGA solutions.

Based on Menta’s eFPGA Core™ programmable logic architecture and on CEA-LETI andCROCUS magnetic technology, this first member of a family of MRAM-based FPGAs,is manufactured in CMOS 130 nm with magnetic junction in 120 nm and provides capacity of 1,444 LUT4, equivalent to approximatively 20K logic gates.

Developed in joint collaboration with Microelectronic department of LIRMM (Laboratory of Informatics, Robotics and Microelectronics of Montpellier) in the frame of SPIN, the large scale initiative for Spintronics devices supported by the French National Research Agency (ANR), this tapeout validates the possibility to stack MRAM technology over traditional CMOS logic and introduces to the market a new type of robust non-volatile FPGA. Market potential of MRAM-based FPGA is being validated for defense, aerospace, automotive and consumer applications.

“This world first MRAM-based FPGA demonstrates the versatility of our eFPGA Core technology”, stated Laurent Rougé, Menta founder and CEO. “Taping out this first MRAM-based FPGA device confirms our intent to build a product strategy that leverages and complements our IP business. One of the key benefits of developing an FPGA with MRAM technology, is that is enables high-density non-volatile FPGA based on leading edge CMOS technology nodes, unlike traditional Flash-based approaches only available on mature CMOS processes.”

Pr Lionel Torres, in charge of the MRAM design project at LIRMM, claims that “MRAM-based FPGA proposes better versatility with partial or dynamic re-configurability capabilities, instant on/off total or partial energy saving”.

About Menta‘s eFPGA Core IP

Menta’s eFPGA Core IP is a programmable logic architecture IP core that leverages Menta’s proprietary ultra-compact architecture to provide the SoC designer with post-fabrication flexibility at near ASIC performance. The Menta eFPGA Core IP is customizable so a domain specific-FPGA (dsFPGA) can be used in a SoC with target applications features, and benefits in terms of area, power consumption and speed. The eFPGA Programmer® tool suite configures the core and supports the tools used to map and place and route the design.

Availability

Menta expects sample of MRAM-based FPGA in Q3 2010. MRAM-based FPGA will be supported with Menta eFPGA Programmer® tool suite.

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
