8-bit microcontrollers have integrated Ethernet peripheral

4 October 2006 DSP, Micros & Memory

Microchip offers a family of devices claimed to be the world’s smallest 8-bit microcontrollers with an integrated IEEE 802.3-compliant Ethernet communications peripheral. The PIC18F97J60 family is optimised for embedded applications, and has an on-chip medium access controller (MAC) and physical layer device (PHY).

By integrating a 10BASE-T Ethernet controller onto a 10 MIPS PIC18 microcontroller with up to 128 KB of Flash program memory, Microchip says it is providing embedded systems designers with a simple, cost-effective single-chip remote-communication solution for a wide range of applications. Microchip also offers a free TCP/IP software stack to reduce development time.

Ethernet is the leading networking technology for local area networks (LANs), and it can be used to connect embedded devices through a LAN to the Internet. Ethernet's infrastructure, performance, interoperability, scalability and ease of development have made it a standard choice for such embedded communications.

Any embedded application that requires Ethernet connectivity can take advantage of the new nine-member PIC18F97J60 microcontroller family. Such applications can include industrial automation (eg industrial control, power-supply monitoring, network/server monitoring and environmental monitoring); building automation (eg fire and safety, access control, security panels, lighting control and VoIP intercoms); commercial control (eg kitchen appliances, drink dispensers, hotel minibars and POS terminals) and even home control (eg security and networked appliances).

Microchip has also created the PIC18F97J60 PICDEM.net 2 development board to assist developers with these new ICs. In addition, the latest version of Microchip's free PIC18 TCP/IP Ethernet Stack can be downloaded at www.microchip.com/tcpip

The 100-pin PIC18F97J60/96J65/96J60, the 80-pin PIC18F87J60/86J65/86J60 and the 64-pin PIC18F67J90/66J65/66J60 are all offered in RoHS-compliant TQFP packages.
