> Yeah, and take a look at the kludge of a charge pump for Vpp. > Looks like a recipie for disaster to me. Looks familiar, except that Wisp628 uses 22uF and 1k instead of 10u/2k2. What's the problem with it (except that a Vdd that is too low to begin with will cause a problem with some older PICs)? For obviousd reasons I would like to know!
