By adding more on-chip memory and functionality to Hitachi Semiconductor's H8/300 series 8-bit microcontroller, engineers produced a new series of devices that are said to be capable of replacing 16-bit MCUs in cost-sensitive applications, such as print-head motor controllers. The H8/3318 model has a 60-KByte ROM to store complex programs and a 4-KByte RAM--the largest on-chip RAM of any 8-bit MCU--to handle the larger storage requirements of such programs. The company claims that design engineers will find the new 8-bit H8/3318 capable of doing the job of a 16-bit MCU or even 32-bit MCU in many applications. Such cost-sensitive applications include fast, precise motor control systems for printers and plotters. Hitachi Semiconductor (America) Inc., Product Code 4176.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
