I'm going to have to take off some points for not identifying whether the A-D converter is important or not. :-) This is a distinguishing feature among the PICs... Microchip has a parametric search table starting here: http://www.microchip.com/stellent/idcplg? IdcService=SS_GET_PAGE&nodeId=74 that is pretty good. I see they have (recently?) removed the "mature" chips into a separate category, and they no longer show up unless you specifically look for them. Start with the "memory Type = FLASH" button and avoid the "mature" chips, and I think most people here will be satisfied.
