Sept. 11, 2006 Microchip Technology Inc has introduced a new family of 8-bit microcontrollers with Embedded Ethernet on-chip. Microcontrollers in the new Microchip PIC18F97J60 family have IEEE 802.3-compliant 10Base-T on-chip Medium Access Controller (MAC) and Physical Layer Device (PHY).

"The need to access embedded applications remotely using Ethernet can be fully realized through the selection of the PIC18F97J60 family," said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division.  "Combined with our free TCP/IP stack, the introduction of the high-performance PIC18F97J60 family enables microcontroller-based applications to be cost-effectively monitored or controlled from a remote location."

Ethernet is, by far, the leading wired standard for embedded networking technology for embedded control. Ethernet is used to network microcontrollers to each other, and when TCP/IP is used over Ethernet, microcontrolers can be networked to local computer systems, as well as the internet.

Targeted applications for the PIC18F97J60 microcontroller family with embedded Ethernet include:
