Post by thread:[PIC] 16HV540

I was just looking at Digikey's web site and it comes across a bit scrambled in lynx so I thought I would verify a couple of things about the PIC16HV540. I thought I might buy a few to experiment with if they are still being produced. It looks like the JW parts sell for about $5.70 however I saw a message saying "non-stock" on a line above the unit price. The problem is that the page when displayed in lynx is oddly formatted and it is kind of hard to tell what goes with what. If this chip isn't being produced any longer, I don't need one for a specific use and will just put a 7805 or similar in the circuit and power some other PIC from that. Thanks.

Thanks for confirming what I was fairly sure I was reading. Since the only thing one gets out of the 16HV540 is a built-in regulator, I think I'll forgo those. Martin McCormick

Microchip wants you to experiment. (That site would likely give lynx fits, though; it even gave my graphical browser fits). I looked at the datasheet for that chip. What's interesting is the high voltage tolerant port, so you can have an arbitrary supply voltage like 7.2v, and then port B's I/O would operate in a 7.2 volt environment, too. And it would tolerate a drifting battery voltage, from a digital standpoint, assuming you are aware of the implications. Barry
