Microchip Technology's new ENC28J60 chip, is claimed to be the world's first 28-pin standalone Ethernet controller. It provides a low-pincount, cost-effective, easy-to-use solution for remote communication between embedded applications and local or global networks.
Designers who require communications for remote control or monitoring are often faced with the complexity of large-footprint, expensive Ethernet controllers that are tailored for personal-computing systems. While most Ethernet controllers come in greater than 80-pin packages, the IEEE 802.3-compliant ENC28J60 offers comparable features in a 28-pin package, according to the company.
The ENC28J60 Ethernet controller employs the industry-standard SPI serial interface, which only requires four lines to interface to a host microcontroller. These features, combined with the company's free TCP/IP software stack for PIC18 microcontrollers, provide the smallest whole-product Ethernet solution for embedded applications.
By adding Ethernet connectivity to an embedded system, microcontrollers can distribute data over a network and can be controlled remotely. Ethernet's infrastructure, performance, interoperability, scalability and ease of development have made it a standard choice for embedded application communications, such as within the growing VoIP market.
Package options for the ENC28J60 include 28-pin SPDIP, SOIC, SSOP and QFN.
