Post by thread:[PIC]: A great solution for the PIC16F877 problems

Sorry for the repetition... finally got the [pic]: right in the subject header: Wan't a PIC that you can code protect from external reads and writes to the EEPROM program memory, AND still allow internal reads and writes under software control (I.E. some type of custom bootloader with perhaps some encryption algorythm), look no further than the new 18F series. I just called Microchip today to ask if the 18F has the problems of the 16F877. The answer is no. The 18F solves this quirk. See for yourself, by looking at the 18Fxxx series data sheet, specifically p.70 and p.206-. And you don't need to wait for the 77A version next march. The 18F series is already available for sampling. Neil Gandler Founder, CTO MAI Technology Inc. P.O.

The 18F series is already available for sampling. I see the link on the web page that says "Purchase Samples Online:" and I go to buy.microchip.com but I don't see any 18FXXX chips for sale. Is there some secret handshake that I don't know about? -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

I went to the Masters where they gave us a 18F452JW marked ES (engineering sample). So, it looks like the chip exists...

how does the 18F452 compare pricewise to the 18F442, and both relative pricewise to the 16F877 ? -----Original Message----- From: pic microcontroller discussion list [.....PICLISTKILLspam@spam@MITVMA.MIT.EDU]On Behalf Of Bob Ammerman Sent: Monday, July 23, 2001 10:13 PM To: PICLISTKILLspamMITVMA.MIT.EDU Subject: Re: [PIC]: A great solution for the PIC16F877 problems (code protect,bootloader) I went to the Masters where they gave us a 18F452JW marked ES (engineering sample).
