At the time of this post, tape out of the company’s SF3301ASIC has been announced as complete. Cryptocurrency (the best-known example of which is Bitcoin) depends on “ledgers” supported by bitcoin “mining” chips. As noted in an arstechnica piece (read it here), while some Bitcoin mining is done on CPUs and GPUs, serious mining requires much faster and lower power ASICs in the hardware.
As posted on the SFARD blog, “By using FDSOI technology not currently present in any other chip on the market, power efficiency when mining with SHA-256 is predicted to reach below the 0.3 J/GH range, and 2.0 J/MH when mining with Scrypt.
“The SF3301 is extremely versatile, allowing you to mine multiple currencies with one device. This means price fluctuations can be harnessed and being forced to turn off your miner is far less likely.
“A condition can arise where altcoins are utilized to cover electricity costs while bitcoin is continuously and simultaneously being mined. This ability is something never seen before with 28nm technology.”Posted March 11, 2015 - Share this Buzz
X-FAB is running a series of webinars on very high-temperature design the 18th and 19th of March 2015. A pure-play analog/mixed-signal and specialty foundry, X-FAB’s broad portfolio includes SOI CMOS processes for use at high temperatures up to 225°C. The event is free, but space is limited, so sign up here.
As noted in the program announcement, an increasing number of applications such as automotive engine management require electronic systems that operate reliably at temperatures above 150°C. Designers are facing the challenges of dealing with changes in electrical characteristics, higher leakage current and thermally accelerated degradation. (To read more about high-temp apps on SOI, click here.)
This webinar looks at the device physics, electrical properties of MOSFETs and NVMs, and degradation mechanisms at elevated temperatures up to 200°C. It will discuss the behavior of CMOS when it is operated at higher temperatures and how the issues that arise can be mitigated by process architecture and design techniques.Posted March 11, 2015 - Share this Buzz

NXP recently expanded its GreenChip line of SOI-based power supply controller ICs with the new TEA1832TS (click here for more product info). Here at ASN, we first covered this line back in 2011 (see that Buzz here), and NXP’s been adding to it ever since.
Smart, green power supplies are one of the most important ways that designers reduce the power consumption of modern electronics. The reason NXP has been using SOI for over 15 years is well explained in this ASN piece from 2009 – read it here.
The TEA1832TS is a low-cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. It makes the design of low-cost, highly efficient and reliable supplies easier by requiring a minimum number of external components. The device is especially suited for medium power applications.Posted March 3, 2015 - Share this Buzz

SiTime’s SOI-MEMS solution is a key part of a new realtime health and fitness tracking solution from MegaChips called “frizz”. MegaChips has announced a partnership with Bosch Sensortec to provide a complete reference design for use of frizz in smartphones, wearables and other personal devices allowing consumers to monitor their activities in real time (read the press release here).
This marks SiTime’s first major announcement since becoming a subsidiary of Mega chips. SiTime leverages SOI-MEMS for high-performance, ultra-low power, ultra-slim timing solutions. (SiTime contributed an excellent piece to ASN a few years ago explaining their SOI edge – you can still read it here.)
Piyush Sevalia, SiTime marketing EVP, said, “SiTime’s groundbreaking MEMS and programmable analog technologies allow us to deliver game-changing MEMS timing solutions. Our MHz and kHz solutions provide the best accuracy, the smallest size and the lowest power, all of which are ideally suited for wearable electronics and internet of things (IoT).”
Frizz is a motion sensor hub with a 32bit DSP based motion engine that can realize high performance calculations used in processing algorithms with ultra-low power consumption in lieu of a microprocessor. MegaChips’ ultra-low power frizz, combined with the SiTime SiT1602 programmable MHz oscillator and Bosch Sensortec MEMS sensors provide more meaningful data, easy interpretation, higher accuracy and ultra-low power critical for longer battery life.
The joint frizz and Bosch Sensortec solution is available now from MegaChips (extensive information is available here).Posted February 23, 2015 - Share this Buzz
