Texas Instrumentsí 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 TIís ARM CPU, go to http://rbi.ims.ca/4927-550.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diegoís Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a personís sweat.
