Fifty cents goes much farther than it used to in the 8-bit microcontroller market. Microchip is selling the PIC16C505 one-time-programmable (OTP) part for 49 cents, and the PIC16CR54C ROM device for 40 cents. The 14-pin parts provide an upward migration path to increased I/O capability for designs based on the company's 8-pin controllers. The OTP part sports 1,024312 words of program memory, 72 x 8 bytes of user RAM, 12 I/O pins, and a 4-MHz internal clock oscillator. The ROM version offers 512 x 12 words of ROM program memory, 25 bytes of user RAM, and 12 I/O pins. Both operate from 2.5 to 5.5V, use 33 single-word instructions, and offer a full-speed 200-nsec instruction cycle at 20 MHz. Microchip Technology: Product Code 4277
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
