What is the reason of not using re-programmable MCUs? PIC16C72A is quite old (my first PIC project back in 1999/2000 used it and the product is still in production now at >100k/year run rate for my previous employer). It is probably more expensive than PIC16F72 now. And if you want to use in circuit debugging, PIC16F72 is not a good choice either as it does not have the debugging silicon built-in. Maybe the newer PIC16F72x or other PICs are better and cheaper. -- = Xiaofan http://mcuee.blogspot.com -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
