Global Unichip delivers ASIC with 2GHz DDR2/3 interface on 40nm LP process

GUC President Jim Lai

Global Unichip, TSMC’s design arm, is manufacturing a consumer electronic applications processor ASIC with a DDR2/3 interface delivering 2.0GHz Mbps from its 40nm low power (LP) process.

Key steps were designing to the performance sweet spot of GUC’s DDR2/3 high speed interface IP, a condensed package substrate, and a PCB through a precise DDR system simulation flow and measurement correlation.

The consumer electronics marketplace for this particular ASIC is mature so both performance and cost are equally paramount.

Cost was reduced by the mature 40nm process, a cost-reducing PCB and a four layer substrate.

Performance would be determined by retaining the speed characteristics of DDR 2/3 interface and optimizing system integration.

While cost-effect, the four layer substrate and cost-reducing PCB limit the performance and production margin of the DRAM read/write rate, so the GUC DDR 2/3 IP performance on the 40nm low-power process was very critical to system performance.

The GUC DDR 2/3 high speed interface IP were implemented with a low jitter clock scheme and high performance memory I/O design that pushed the operational speed 10%-15% beyond the published limits.

GUC engineers enhanced the performance through a customized system chip, package, broad simulation flow covering, signal and power integrity analysis and silicon measurement correlation.

“The most interesting thing about this challenge is that required the ingenuity of both IP and systems engineering,” said Jim Lai, President of GUC. “The complexity of the business and technology challenges created a complexity that required innovative thinking and execution on a number of levels,”

Lords check national research priorities

Tomorrow, the House of Lords Science and Technology Committee will start a short inquiry into national priorities for scientific research.

“This inquiry constitutes a very brief spot check of scientific research priorities and related issues ahead of the publication in the autumn of the Government’s science and innovation strategy,” said the Lords. “With research areas as diverse as energy, the digital economy, robotics, space exploration, food security and regenerative medicine, to name a few, the Committee will look at the issue of where public funds should be directed, and why.”

It will also explore the changes that need to take place to improve the UK’s international standing in science and innovation.

Witnesses attending the first of three evidence sessions are:

Dr Sarah Main (Director, Campaign for Science and Engineering).

Professor Graeme Reid (professor of science and research policy, University College London).

Kevin Baughan (director of technology and innovation, Technology Strategy Board).

Questions will include:

What are the main priorities for scientific research?

What are the challenges in setting out priorities?

Should we prioritise according to direct benefit to society?

Should we prioritise according to economic benefits to UK plc?

Should we aim for excellence in a few areas, rather than competence across them all?

Who should decide where we as a country should focus our research – the researchers or the funders?

Where does the research strategy leave the overall science budget?

The session is at 10.40, is open to the public, and will be live on the internet.

Further hearings are planned for 8 and 22 July.

The Lords Science and Technology Committee, chaired by Lord Selborne, has a broad remit: ‘To consider science and technology’. It scrutinises Government policy through cross-departmental inquiries into a range of activities.

50W blue laser module for projectors

Osram is packing up to 20 blue laser chips into 26x35mm for laser projectors, delivering up to 50W.

“This means that professional laser projectors can achieve a brightness level of more than 2000 lm with only one component,” said the firm, adding: “Osram developers are the first to adapt the ‘butterfly’ package for projection applications.”

Called PLPM4 450, the module has four copper bars with up to five blue laser chips connected in series and operated at 2.3A each. 50W of light is typically delivered from 165W (50°C) in with wavelengths of 440 to 460nm – To this possible, single-chip output has been doubled from 1.6 to 3.2W and thermal resistance improved.

According to Osram, some laser projectors use blue laser diodes in combination with a converter wheel produce red, green. “If several modules are installed, levels far in excess of 5000 lm are then possible, for example for large conference rooms.

Lifetime to 50% is up to 20,000hr, depending on ambient conditions.

Volume production will start at the end of 2014, with samples available in the summer. Osram Specialty Lighting will integrate the module with phosphors into ‘phaser’ (phosphor and laser) modules for use in existing projector architectures.

Most Taiwan makers unlikely to enter Android One supply chain

While Google is ambitious to boost sales of its planned Android One-based smartphones to emerging markets, most Taiwan-based handset component makers are unlikely to obtain orders for Android One smartphones because they are less price-competitive compared to China-based rivals, according to industry sources.
