Texas Instruments’ TMS470R1B1M ARM7-based MCUs with 1MB Flash memory have 60 MHz, 32-bit chips and also carry 64 kbytes of RAM. A High-End Timer (HET) co-processor provides greater accuracy in timing functions like period and pulse measurements, output compare and Pulse Width Modulations (PWMs). The HET co-processor runs independently in parallel with the ARM7 CPU, providing significantly higher throughput. Peripherals include two CAN controllers, five I2C modules, three serial communication interfaces, two serial peripheral interfaces and a 16-channel DMA controller.
Pricing for the 144-pin device starts at $14.95 for 1,000. For more information on TI’s ARM CPU, go to http://rbi.ims.ca/4927-550.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
