User s manual ET-MINI ENCJ0 ET-MINI ENCJ0 ET-MINI ENCJ0 is a module that is designed to be intermediary connections between Microcontroller and Ethernet Network. It supports operation of Protocol TCP/IP by using IC ENCJ0 that is IC Ethernet Controller to support IEEE 0. standard communication and connect signal controller through SPI Bus with maximum high speed 0 Mb/s. Microchip supports Microchip TCP/IP Stack to develop program and user can download it free without any charge from Microchip website (www.microchip.com). The briefly specifications of ENCJ0 is described below; Specifications of IC ENCJ0 General: - IEEE 0. compatible Ethernet Controller - Integrated MAC and 0BASE-T PHY - Kbyte Transmit/Receive Packet Dual Port Buffer SRAM - Programmable Automatic Retransmit on Collision - Programmable Padding and CRC Generation - Programmable Automatic Rejection of Erroneous Packets - SPI Interface with speeds up to 0 Mb/s - Supports Full and Half-Duplex modes Buffer: - Configurable transmit/receive buffer size - Hardware managed circular receive FIFO - Byte-wide random and sequential access - Internal DMA for fast memory copying - Hardware assisted IP checksum calculation PHY: - Wave shaping output filter - Loopback mode MAC: - Support for Unicast, Multicast and Broadcast packets - Programmable pattern matching of up to bytes within packet at user defined offset --
User s manual ET-MINI ENCJ0 - Programmable wake-up on multiple packet formats, including Magic Packet, Unicast, Multicast, Broadcast, specific packet match or any packet The method to connect device with Microcontroller is quite easy because it is SPI Bus Interface that uses fewer pins. For power system of ENCJ0 is Volt IC if user wants to run with Volt Microcontroller, user must use Buffer Circuit that is designed by ETT. It supports the connection of power system between Volt and Volt internal Board ET-MINI ENCLJ0; in this case, user can select power system by setting Jumper V/V. Picture displays block diagram of the signal connection between ENCJ0 and Microcontroller. --
User s manual ET-MINI ENCJ0 +V +.V Warning: User must correctly set Jumper follows the truly usage otherwise your device maybe damaged. Picture displays structure of Board ET-MINI ENCJ0. From picture above, HD and HD are designed to connect with Board ET-PICWEB V and ET-dsPICWEB V; for HD is designed to connect with other Microcontrollers and it is designed in the type of ET-MINI from ETT. --
