2 INTRODUCTION: This board allows you to easily develop Ethernet connectivity applications. It has everything you normally would need for such applications: power relays which you can command through web interface, LCD display which will display messages you fill in web forms, analogue inputs for connection to sensors, digital optoisolated inputs, trimmer potentiometer, temperature sensor, Ethernet connector. With this board you can easily automate your home and then control and monitor it from any point in the world via Internet. An extension connector is available so you can connect custom made hardware to the board. The PIC8F97J60 has 8KB Flash program memory and there is external Mbit (8KB) flash memory for data storage. The on board DC/DC converter makes this board very tolerant to the external power supply which could be in 9-5V DC or 7-8V AC range. The bridge rectifier on the input allows AC and DC adapters to be used and makes power supply polarity problems go away. BOARD FEATURES: - PIC8F97J60 microcontroller with embedded Ethernet MAC and PHY and 8KB Flash programming space - Mbit on board serial flash for web pages storage - ICSP/ICD connector for programming and debugging with PIC- ICD and PIC-ICD-POCKET. - Temperature sensor - Trimmer potentiometer connected to analogue input - Two relays 0A/50VAC - Four optoisolated digital inputs - Twelve analogue inputs on terminal block - Two buttons - LCD6x with backlight - RS interface - Ethernet interface - Complete web server and TCP-IP stack support as per Microchip's open source TCP-IP stack - Terminal block for power supply works with 9-5 VDC power supply - Extension header to connect to other boards - Dimensions 0x08 mm (.7x.5") ELECTROSTATIC WARNING: The PIC-MAXI-WEB board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS: Cables: Depends on the used programming/debugging tool. It could be.8 meter USB A-B cable to connect PIC-ICD-POCKET or PIC-ICD to USB host on PC or RS cable for PIC-ICD-TINY and PIC-ICD. You will Page

3 need a serial cable if not for programming, than for configuring the board. You will also need a LAN cable. Hardware: Programmer/Debugger Olimex programmers are applicable, for example PIC-ICD, PIC-ICD-POCKET, PIC-ICD-TINY or other compatible programming/debugging tool.!!!warning!!! When you want to program this microcontroller with PIC- ICD, PIC-ICD-POCKET or PIC-ICD-TINY, before connecting the programmer to your target board, you should first connect the programmer to your computer and open MPLAB. There, first from menu Configure Select Device choose the microcontroller you are about to program, then from menu Programmer Select Programmer choose MPLAB ICD, wait while MPLAB is downloading operation system, and after ICD is connected check in menu Programmer Settings Power there is option Power target circuit from MPLAB ICD this option should be forbidden, you could not select it. Now it is safe to connect the programmer to your target board. Software: PIC-WEB is tested with MPLAB IDE v MPLAB C8 C compiler. It is possible that the stack might not function properly if used with later versions of MPLAB IDE. You will also need a terminal program configured at 9 00 bps, 8N and no flow control. PROCESSOR FEATURES: PIC-MAXI-WEB board use MCU PIC8F97J60 from Microchip with these features: - IEEE 80. compatible Ethernet Controller - Integrated MAC and 0Base-T PHY - 8-Kbyte Transmit/Receive Packet Buffer SRAM - Supports One 0Base-T Port - Programmable Automatic Retransmit on Collision - Programmable Padding and CRC Generation - Programmable Automatic Rejection of Erroneous Packets - Activity Outputs for LED Indicators - Buffer: o Configurable transmit/receive buffer size o Hardware-managed circular receive FIFO o Byte-wide random and sequential access o Internal DMA for fast memory copying o Hardware assisted checksum calculation for various protocols - MAC: o Support for Unicast, Multicast and Broadcast packets o Programmable Pattern Match of up to 6 bytes within packet at user-defined offset o Programmable wake-up on multiple packet formats - PHY: Page

9 BOARD LAYOUT: POWER SUPPLY CIRCUIT: PIC-MAXI-WEB can take power only from power connector PWR, where (9- ) VDC or (6-9) VAC external voltage source has to be applied. The board power consumption is about 00 ma with all peripherals and MCU running at full speed, relays and LEDs on and working Ethernet connection. RESET CIRCUIT: PIC-MAXI-WEB reset circuit is made with RC group R0 0k and C 00nF. Serial resistor R 0Ω is used to prevent fast C charge and discharge when PIC8F97J60 is being programmed. Manual reset is possible by the RESET button. CLOCK CIRCUIT: Quartz crystal 5MHz is connected to PIC8F97J60 pins OSC (CLK) and OSC (CLKO). Internal PLL circuit can multiply this frequency up to MHz..768 KHz quartz crystal is connected to PIC8F97J60 pins TSO and TOSI for its internal Timer. Page 9
