Fast 100 Mbps Ethernet PICtail? Plus Daughter Board

Overview

The Fast 100 Mbps Ethernet PICtail? Plus Daughter Board (AC164132) is an Ethernet

demonstration board for evaluating Microchip Technology’s ENC424J600 and ENC624J600

stand-alone 10/100 Ethernet controllers. It is an expansion board compatible with many

PICtail and PICtail Plus host boards, including the Explorer 16, PIC32 I/O Expansion Board,

PICDEM.net? 2 and PIC18 Explorer development boards.

Features

? ENC624J600 10/100 Ethernet Controller with factory preprogrammed MAC address (see

“ENC424J600/624J600 Data Sheet” (DS39935) for additional information)

? 25 MHz oscillator and integrated magnetic RJ-45 connector

? PICtail Plus Daughter Board edge contacts for SPI or PSP connection to Explorer 16 and

PIC32 I/O Expansion Boards

? PICtail Daughter Board headers for SPI connection to PICDEM.net 2 and PIC18 Explorer

Boards

? Configuration jumpers for PSP Modes 1, 2, 3, 4, 5, 6, 9 and 10 under PMP control with

automatic pinout remapping

? Current monitoring jumper

? Ethernet crossover switches

? 3.3V LDO regulator with shutdown for very low Sleep current

? 3.3V to 5V SPI level translation for the PIC18 Explorer

? SSL encryption add-on software CD for the Microchip TCP/IP Stack

Getting Started

The Fast 100 Mbps Ethernet PICtail Plus Daughter Board must be plugged into a Microchip

Explorer 16, PIC32 I/O Expansion Board (with suitable PIC32 Starter Kit), PICDEM.net 2 or

PIC18 Explorer development board. However, before making any connections, ensure that

the JP2, “I SENSE”, jumper has a shunt installed, shorting the two pins.

The connection to the host motherboard differs based on the interface mode desired and

motherboard type.

Explorer 16

For purposes of getting started, use the ENC624J600 in SPI mode. To do this, insert the

Fast 100 Mbps Ethernet PICtail Plus J2 side edge contacts into the topmost position of

the J5 slot on the Explorer 16. Pin 1 on J2 of the PICtail Daughter Board should align with

Pin 1 on J5 of the Explorer 16. The Ethernet cable will connect to the PICtail Daughter

Board on the side closest to the Explorer 16 Board’s four push buttons.

PIC32 I/O Expansion Board

The PIC32 I/O Expansion Board is very similar to the Explorer 16. If using a

PIC32MX360F512L based Starter Kit, insert the Fast 100 Mbps Ethernet PICtail Plus J2

side edge contacts into the topmost position of the J4 or J2 slots on the PIC32 I/O Expan-

sion Board. Pin 1 of J2 on the PICtail Daughter Board should align with the Pin 1 slot on

the PIC32 I/O Expansion Board. If using a PIC32MX460F512L based PIC32 USB Starter

Board, insert the PICtail Daughter Board’s J2 connector into the middle position of J4 or

J2. This will result in Pin 1 of J2 on the PICtail Daughter Board aligning with Pin 33 on the

PIC32 I/O Expansion Board.

PICDEM.net 2

The PICDEM.net 2 uses the PICtail Daughter Board thru-hole headers to interface using

SPI mode. To make this connection, insert the Fast 100 Mbps Ethernet PICtail Plus J4

right angle header into the J5 female header on the PICDEM.net 2. Pin 1 on J4 of the

PICtail Daughter Board, labeled “RE2”, must align with Pin 1 on J5 of the PICDEM.net 2

(also labeled “RE2”). This correct orientation does not connect the 2x3 J3 header to

anything. The Ethernet cable will enter the PICtail Daughter Board from the same

PICDEM.net 2 board edge that contains the two 10Base-T Ethernet jacks.
