The market for products or services that are Internet
related is HOT! Increased amounts of money and
design resources are being thrown at these products
and services. One significant portion of this trend is to
embed the Internet or, in other words, make embedded
products have the capability to connect to the Internet.
It is estimated that by the year 2005, the number of
embedded applications with the ability to connect to the
Internet will be larger than the number of PCs by a fac-
tor of 100 or more.
The latest in PDAs and cellular telephones allow the
user to access stock quotes, sports scores, E-mail, and
more. The other advantage of the movement to embed
the Internet is enabling client devices, such as appli-
ances and vending machines, to connect to the Internet
and upload status information. The price for such prod-
ucts is being reduced dramatically due to the introduc-
tion of new technology. AN731
Embedding PICmicro Microcontrollers in the Internet
The application note presented here is based on the
Author: Rodger Richey/Steve Humberd block diagram shown in Figure 1. It consists of the
Microchip Technology Inc. PIC16F87X microcontroller, the Seiko iChipTM
Chandler, AZ S-7600A TCP/IP stack IC, and the ISOmodemTM
Si2400 and Si3015 D
