    Toaster Oven Hotspots

    Hey Brad, I have not been back on in a while, but your suggestion sounds like a great method. I am also looking at replacing my temp sensor, as it may be reporting lower than actual temp or may be in a cooler spot. I will let you know what I find, thanks!!!

    Need Spartan FPGA firmware retargeted for newer device

    Hello All, I have a product that has been using the Xilinx XCS05-3VQ100 since 2002 and need to have the firmware retargeted for an updated, easier to get (and cheaper) device of the same foot print. Basically a drop in replacement. The major issue is that it was done using the VERY old...

    Best Flux for SMD reworking

    I have been using Kesters no clean flux pins, have gone through 3 of the 5 I purchased. I have been VERY happy with the no clean portion, but unless I use gobs of it (wasting much of it), it is not as effective as the radio shack paste I was using (which greatly annoys me with regard to...

    FPGA has been obsoleted, need to choose Microcontroller for next product revision

    I spent (too many) hours this weekend trying to locate and compare options, but really went in circles. There are just too many options available, for a NOOB like me. The RF is a nice feature, but not really a key selling point for the product. There is already 1 cable required for the BCD...

    FPGA has been obsoleted, need to choose Microcontroller for next product revision

    Dean, Thanks for the input! I looked at the datasheet and this unit seems more like a replacement for the entire PCM, which is beyond the scope of our product. I changed my description above which SHOULD have said EPROM emulation instead of the more generic term of "replacement". Our product...

    FPGA has been obsoleted, need to choose Microcontroller for next product revision

    FPGA obsoleted, need to select new FPGA or Microcontroller for next product revision Hello All, We have been using the Xilinx XCS05 in our current design for almost a decade. It was obsoleted last year, but I have enough on hand to last approximately a year. The application is Automotive...
