Thats where the Philips CoolRunners show their strength, they use virtually no power. Oops, Philips sold the series to Xilinix and the chips Peter talk about are the CoolRunners. I believe Xilinix has another name for them, but go by Peters type and you will find the info. I will, after a couple of years of SW only be back in HW probably in May and by then I will have the names straight.
Have a good weekend
