A followup from a question on yesterday about dynamically turning RAM and peripherals on a microcontroller on and off. Microchip and Atmel responded to me:
For both Atmel and Microchip: for peripherals, you can stop the clock to peripherals as well as turn off the power supply to the peripheral.
Atmel RAM: "For ultra low power micros users can normally select if they want to power the entire SRAM or parts of it. This is new technology that is rolling out fast now"
"For peripherals Atmel does clock gating (i.e. remove the clock source to the peripheral) on devices in low leakage processes where switching is the major contributor to power consumption. This includes tinyAVR, megaAVR and AVR XMEGA. For products in denser process geometries where not only switching, but also leakage is a big contributor we have inplemetned power islands for both peripherals and SRAM, example products are SAM7L, UC3L and SAM4L"
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
