Post by thread:[PIC] 20I vs 20 Question

What is the difference between these two parts (i.e. what does the "I" denote)? I suspect the package, but I can't find any information on it in the data sheets. 16F84A-20/P 16F84A-20I/P John Clark Indianapolis, IN

"I' denotes industrial and means it is spec'ed -40degC to +85degC as compared to the commercial (no letter) 0 to +70degC _____________________________ Lance Allen Technical Officer Uni of Auckland Psych Dept New Zealand http://www.psych.auckland.ac.nz _____________________________

In the last few pages of the data sheet there is a page telling you the package markings. In this case, the I denotes industrial Temp specs. The P denotes a plastic DIP package, 20 is the max speed (MHz), and the A indicates that this chip uses die revision A (the first revision after the original production version) The lack of the I indicates a commercial temperature version. I hope this helps! -Adam "Clark, John" wrote: > > What is the difference between these two parts (i.e. what does the "I" > denote)?

I is the Industrial Package - i.e. industrial temperature range of -40C to +85C They cost more. Look on the "Product Identification" sheet on your data sheet Dan (I love the easy ones) Hart ----- Original Message ----- From: "Clark, John" <spam_OUTJohnCTakeThisOuTININ.COM> To: <.....PICLISTKILLspam@spam@MITVMA.MIT.EDU> Sent: Wednesday, June 07, 2000 4:30 PM ...
