PICNet 1 - Products

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