General Description<br />
The <strong>PICNet</strong> 1 is a versatile development<br />
prototype board that supports a variety of 28<br />
and 40 pin Microchip Technology 8-bit<br />
microcontrollers.<br />
The board includes a full 10BaseT Ethernet<br />
interface based on Microchip Technology<br />
new ENC28J60 [C1] IEEE 802.3 Stand-Alone<br />
Ethernet controller with integrated SPI bus<br />
interface, MAC and 10BASE-T PHY (ENC).<br />
Taking advantage of the SPI bus the board<br />
also counts with a SD/MMC memory card<br />
socket with logic interface with the<br />
microcontroller, and an 8 pin IC socket for a<br />
serial EEPROM memory such as the<br />
Microchip Technology 25LC256.<br />
In addition the <strong>PICNet</strong> 1 includes an RJ-11<br />
ICSP interface connector for MCU<br />
programming and debugging with<br />
development tools such as Microchip<br />
Tecnology ICD2, and a standard RS-232<br />
serial interface.<br />
The 2”x2.25” prototype area has 437<br />
connection points available with 0.1”<br />
spacing and easy access to power supply<br />
sources and MCU I/O ports, and to 8 user<br />
LEDs (limiting resistors included).<br />
The clock source for the MCU can be<br />
selected via configuration jumpers or<br />
installing the required components.<br />
<strong>PICNet</strong> 1<br />
Available clock sources include: a surface<br />
mount or thru hole crystal, or a ceramic<br />
resonator, or a half can oscillator, or the<br />
clock output from the Ethernet Controller.<br />
Also solder pads are available if you wish to<br />
install a 32KHz Crystal and load capacitors<br />
to use the MCU Real Time Clock features.<br />
The <strong>PICNet</strong> 1 counts with a full bridge<br />
rectifier and +5V and +3.3V 1A Voltage<br />
regulators and requires a stable 7 - 9V DC<br />
power source with at least 250mA.<br />
