We are having similar problems in UK. Atmel Dataflash parts are unavailable until further notice, nobody will give a delivery time. Many AVR processors 6 months in any quantity. We have used Microchip PIC on a recent project (they are not bad processors these days, though the IDE

What I've come across in many automotive devices is a potting compound that is almost like kids slime. Looks glossy, but is jelly soft. I suppose it it allows thermal expansion, and offers a huge physical barrier to dirt, but I don't know if it's servicable. Most likely not. It's

Yes, I did misunderstand. So I can plug the AVRISPmk2 into the header for straight programming, or plug the JTAGmk2 into the same header for in-chip debugging? If so, are there any limitations on in-chip debugging via a PDI 2-pin header versus a separate JTAG 4-pin header? Steve

Hi Amit, Why would you need a device in a DIP package? A FET only has three leads. If you need to test it on a breadboard, use something in a TO-92 or TO-220 package. What is the failing device, anyway, and where did you get it? I swear that half of electrical engineering these d

BSS138 is packed in sot23, so if you want to test it, you can solder the pins (wires) as you need :), but don't forget that this is n-channel FET, you must open it with logical "0". If you are "worried" with this, find the nearest p-channel fet and use it the same way Eugene
