The PIC 16F628: Why the PIC 16F84 is now obsolete. Note that this page has been updated to talk about the even bigger, better, and badder PIC 16F88. Be sure to check it out. Be sure to check out my new languages page where I talk about cool crossplatform Languages for the PIC. Also read to the bottom for an update on even newer, jampacked PICs that you should consider adding to your toolbox. For nearly a year now I've been advocating the use of the 16F628 for new small pin package PIC projects. After writing dozens, if not over a hundred, posts on the subject. I'd like to start by saying that the 16C84, the 16F84, and the 16F84A are all outstanding parts, especially for the hobbyist. However at this point there is a lot of inertia. Microchip has several new flash based products.
Finally the kicker: That's right. The 25 part price of the 16F84A is $3.69 at Digikey. As one local Atlanta radio station ad states: The 16F628 is bigger, better, badder, and cheaper. So that's it. It's pin and virtually code compatible. What is a PIC Microcontroller? Gpsim. Simulador de circuitos para linux. Pues tienes que probarlo con la version wine 1.01 que es la version estandar, te cuento como me funciono: primero instale proteus 7.5 sp 4 creo y no me corrio con la version mas moderna de wine luego probe con el wine 1..10 q tampoco corria, pero luego instale office 2007 y note que descargo algunas librerias, y es ahi donde intente de nuevo con el proteus y corrio de maravilla aunque no he probado los puertos virtuales USB y LPT de isis, y por ultimo decidi probar con el crossover y con esta tambien funciono de maeravillas funcionaban hasta el pic 18f4.... pero luego he intentado instalar autocad 2010 y para eso descarge algunas librerias y las instale a wine y creo q se actualizo y yano me funciono el proteus, asi solo espero para sacarme tiempo para poder reparar mi ubuntu 9.10 para que corra proteus y tambien el PCW para PICs.
