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.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Microchip recently released the 3D TouchPad, the first USB PC Peripheral device that couples 2D multi-touch input with 3D air gesture technology. The company seeks the help of developers to further enhance the capabilities of the technology.
To give engineers a better idea of the range of resins and polymers available as alternatives to other materials, this Technology Roundup presents several articles on engineering plastics that can do the job.
