E-blocks™ internet board
Document code: EB023-30-1
2. General information
1. Description
The Internet E-Block allows Internet and Ethernet capabilities to be easily added to your microprocessor and FPGA
designs. It consists of a TCP/IP stack, a physical-layer chip and an Etherne t socket.
Communication between this E-Block and a microcontroller is achieved using an I
Two Flowcode components are available that simplify the use of this E-Block. The first is a "WebServer"
component that facilitates the creation of an embedded web server with no knowledge of TCP/IP protocols needed.
The second Flowcode component, the "TCP/IP" compone n t, allows user s to create a custom appl ica tio n using
various protocols (TCP, UDP, IP or Ethernet), such as ARP scanners, SMTP email clients, har dware firew alls, etc,
etc.
'C' and Assembly users can access all the features of this device without the need to embed an extensive TCP/IP
stack into their own firmware.
2. Features

as the PIC16F88 you may need to create your own C/ASM code.
If you are using PICmicros then select +5V systems (J5) as PICmicros operate from +5V.
