Summary
There is nothing new about implementing TCP/IP
(Transmission Control Protocol/Internet Protocol) on
Microchip microcontrollers. Interested developers can easily
find many commercial and non-commercial implementations
of TCP/IP for Microchip products.
This application note details Microchip’s own freely
available implementation of the TCP/IP Stack. The Microchip
TCP/IP Stack is a suite of programs that provides services
to standard TCP/IP-based applications (HTTP Server, Mail
Client, etc.), or can be used in a custom TCP/IP-based
application.
Summary
The 25XXX series serial EEPROMs are SPI compatible and
have maximum clock frequencies ranging from 3 MHz to
20 MHz. The SPI module available on dsPIC33F DSCs and
PIC24F MCUs provides a very easy-to-use interface for
communicating with the 25XXX series devices.

The Microchip TCP/IP Stack is implemented in a modular
fashion, with all of its services creating highly abstracted
layers. Potential users do not need to know all the
intricacies of the TCP/IP specifications to use it. In fact,
those who are only interested in the accompanying HTTP
Server application do not need any specific knowledge of
TCP/IP .
The largest benefit of using the SPI module is that the
signal timings are handled through hardware rather than
software. This allows the firmware to continue executing
while communication is handled in the background. This also
means that an understanding of the timing specifications
associated with the SPI protocol is not required in order to
use the 25XXX series devices in designs.
