The IP newsletter from CAST, Inc. — February 24, 2016

It's Show Time!

It's always exciting this time of year to escape from the office and meet current and potential customers out in the world.

This week is our fourth year exhibiting at the gigantic, stimulating Embedded World fair in Nuremberg. Next week we're trying the highly-respected Design and Verification Conference (DCVCon) in San Jose, California. And of course the big Design Automation Conference will be here soon; this will be CAST's 21st time exhibiting at DAC.The CAST and SIlesia Devices team at Embedded World Nuremberg 2016

Supposedly for image building and lead generation, we find trade shows to be especially important just for contact.

Questions we get from designers give a good sense of the changing role of IP in their lives. These evolved from "what is IP?" in the early years to "what sorts of IP do you have?" to today's more typical "why is your XYZ-specific core better for me than this other provider's?"

We also get excellent face-to-face time with the press and media folks—usually a great learning exchange in both directions—catch up with old partners, discover potential new partners, and get far-flung CAST employees together for a few days of focused teamwork and fun.

Investing in trade shows in today's web-based world is not an easy decision, but we've found it to be a smart move. If you're attending any of these events, help make our investment—and yours—even more worthwhile by stopping by to chat. Or just give me a call or email any time.

CAN Bus Controller Core Gets Time-Triggered TTCAN

CAN FD IP from CAST, Inc.Our CAN-CTRL CAN 2.0 & CAN FD Bus Controller Core is one of the first- and best-available for ASICs and FPGAs. Now our partner Fraunhoffer IPMS has made it even better for you, with new support for Time-Triggered CAN (TTCAN). This means the Controller covers all the popular protocols:

  • CAN 2.0 and CAN FD — ISO 11898-1:2015 and earlier ISO, and Non-ISO (Bosch) versions;
  • TTCAN — Time-Triggered CAN (ISO 11898-4 level 1); and
  • Optimized support for the AUTOSAR and SAE J1930 specifications.

This is already the first soft CAN controller core to undergo the rigors of a CAN In Automation Plug Fest, and we are scheduled to do it again at events this March and April.

Free Webinar: Easier 8051 Development with IAR Embedded Workbench for 8051

IAR Systems logoOur 8051 Microcontroller IP Cores plus the integrated development environment from IAR Systems together give you the easiest, quickest pathway from competitive product concept to profitable shipping product. Now see exactly how the IAR Embedded Workbench for 8051 helps you make the most of our 8051 cores in this live, hands-on webinar.

The webinar walks through an example design to show how the integrated toolset and seamless workflow of IAR Embedded Workbench for 8051 can significantly boost your code quality and development IAR Systems Embedded Workbench for 8051s helps developers create quality code quickerproductivity. Topics include:

  • IAR Systems and CAST and their Benefits to You
  • A Walk Through of IAR Embedded Workbench for 8051
  • How to Automatically Migrate Projects to IAR Embedded Workbench
  • Development Cycle Demonstration using the CAST Talos Board Kit with R8051XC2 IP Core
  • Technical Q & A

The 45-minute webinar is aimed at practicing embedded system designers but will also benefit project managers and marketing and sales staff. It will run live multiple times on March 17, and will be available later online. We hope you can join us; please check our website or Twitter feed for times and registration details coming soon.

8051 MCU IP Family Gets Tiny 80251

It's not just our 8051 development ecosystem that keeps improving, but also our actual 8051s.

80251 MCU IP from CAST, Inc.We've just introduced a new 16-bit 80251 microcontroller core that's remarkable for its very small size. This T80251XC3 Tiny 16-bit 80251 MCU Core gives you the 16- and 32-bit data processing capabilities of the 80251 architecture, but it needs as few as 13K gates. That's a silicon area no larger than a fast 8051, and considerably smaller than a typical 32-bit processor.

Moreover, this Tiny '251 helps reduce system-wide energy usage via greater code density—enabling the use of smaller firmware memory units—and its CISC design with more complex addressing modes reduces the necessary number of power-consuming load-store operations (which typically comprise >20% of the code for 32-bit RISC designs).

Sourced from partner Silesia Devices—one of the most experienced 8051 IP development teams in the world—the design is carefully optimized for performance and achieves a Dhrystone benchmark score of 0.1455 DMIPS/MHz (using the Keil compiler). A fully configurable set of proven peripherals is included and the 8051 ecosystem is mature, simplifying and reducing the risk of developing systems using the T80251XC3.

The new core is available now, with cost-effective, royalty-free licensing and versions for ASICs or FPGAs.
