jg, You can't compare Platform Manager with a microcontroller+ADC, because these devices perform different functions. Platform Manager can integrate board management functions such as hot-swap controller, supervisor, power feed controller, supervisor and sequencing, as well as reset sequencing, fault logging, providing interface to memory mapped I/O, etc. The voltage monitoring is performed using precision comparators that detect faults within a few 10s of microseconds and prevents the main processor from corrupting flash memory. A microcontroller with ADC really cannot be used to monitor for supply faults because its response time for detecting faults is determined only by the interval between voltage monitoring interrupts. It cannot be used for any other board power management functions such as power feed, hot swap etc. In general, a microcontroller is good for performing some of the management tasks that can tolerate response times commensurate with the microcontroller's response times. However, for applications that need real time voltage monitoring with response times of less than 100 microseconds, that is best done with hardware comparators.#

I'm scratching my head over the Platform Manager. At a monster 128 pins (!), for the smallest version, and a narrow Vcc spec, and a price of $3.75/volumes, (vs alternatives like 12 bit ADC/32bit uC/wider Vcc for 50c/volumes) - I'm trying to think what Power Manager question, has the Lattice part as the answer ? I can think of some Power Inverter apps, but the CPLD clock is only 250KHz, and the FPGA specs adequate fabric speeds, but makes no mention of a PLL clock to generate those speeds.

Going through the related article "Lattice Platform Manager aims to cut BoM by 50 percent" by Colin Holland posted on 10/12/2010 I understand why they talked about 50% BOM cost reduction...this is only true if the user has requirement implementing all those functions (hot swap, voltage monitoring, supply or'ing, supply sequencing etc.) in his/her design.

Reducing bill-of-materials (BOM) costs over 50% would really be great...but isn't it lot of promise? I understand Lattice has the unique power management & programmable analog IC options to offer in their portfolio. Unfortunately I could not get a chance to find them in my designs. Anybody who has used the programmable analog ICs want to share experience?

I'm sure Lat won't keep anything secret for long. (I'll pass on yr msg Max). Heck of a show though, miles and miles of it. Too much of a good thing, probably, discipline essential otherwise you don't get anything done. Good opportunity to meet a lot of Far East companies. Also you see lot of smaller, local Euro outfits you don't see in the global press.

Mark, Probably not this year, but stay tuned for 2011.

Hi Mark -- I don;t know, but I will ask them immediately and -- in fact I will ask them to reply to your comment (let's see how quickly they respond :-)

This sounds like an event that is not to be missed. It's too bad it is taking place in Germany and I won't be able to attend this year. Will Lattice be presenting the same information at any U.S.-based trade shows this year?

Sadly I won't be going to Electronica this year -- but if you go then please drop by the Lattice Booth and say "Max says Hi!"
