Advance Information TPOUTTPOUT+ VSSTX DS39623E-page 1 ENC28J60 Description The Microchip Technology Inc. ENC28J60 is a standalone Ethernet controller with an industry standard Serial Peripheral Interface (SPITM). It is designed to serve as an Ethernet network interface for any microcontroller equipped with SPI. The ENC28J60 meets all of the specifications for IEEE 802.3. It incorporates a number of packet filtering schemes to limit incoming packets. It also provides internal DMA for fast data throughput and support for hardware assisted IP checksum calculation. Communication with the microcontroller is implemented via SPI, with data rates up to 10 Mbit/s. Dedicated pins are used for LED link and activity indication and for transmit and receive interrupts.

Note the following details of the code protection feature on Microchip devices: * * Microchip products meet the specification contained in their particular Microchip Data Sheet. Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. Microchip is willing to work with the customer who is concerned about the integrity of their code. Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable." * * * Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products. Attempts to break Microchip's code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
