Alaskaman66- Some good questions.The Platform Manager uses the current sense circuitry and the on-board FET to sense and control current onto the board. If the spikes are long enough it can easily manage board insertion/removal events. All timing is programmable- ramp rate too. Energy storage needs to be done external (super cap maybe?).
The Power to You book is a great reference and should be able to answer your questions in precise detail. It is available for free here.
With the Lattic platform manager, I have some questions. On board removal, does the LPM mitigate any voltage spikes, say from an inductive or capacitive load? Is there any sort of sequenced regulator turn off or energy storage capability, to make sure, for example, that the MCU is the last thing to lose power and has time to do POST? Also, does the FET switch stay off until the 12V bus stabilizes upon board re-insertion? Can the LPM monitor input voltage or current and disconnect via the FET upon seeing excessive excursions in either input voltage or system current? Are those parameters programmable?
@Alaskaman66- The comparitors can typically be set to fairly precise levels. Some devices have automatic windowing functions to so you can tell if a voltage is 'out of range' prior to sending an interrupt to the controller.
Alaskaman66- MCUs tend to have a larger number of bits and better conversion times (since the try and target audio applications and above). The devices covered today are more targeted at sensors and slower applications like that...
DouglasEaton- I'm stuck using a PC for my hardware projects too. I wish the Mac was better supported. Running in emulation mode might work- I have not tried it... Larger FPGA devices would probably be a problem however..
tomorrow i can't be able to attend because of our meeting at ASHRAE Oryx Chapter as one of the member of the BOARD OF GOVERNORS...But still, archive is there I can have a look and attend maybe before on the 4th day class...
By high power control, are you basically referring to switching voltages above the supply voltage for the chip? Say 120 VAC or 48 VDC? I imagine a high current (power) aplication would still require an external device, such as a solid state relay.
Warren - great presentation. Rob, Thanks for keeping me on track with the slde numbers - came in handy as I kept rebooting the presentation to hear the audio = tomorrow I will hard-boot with my work boots on! :-)

Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the worlds biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sams Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesnt come from conventional, statistics-based tests but from accelerated stress testing.
Theres a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
