Microchip's PIC18F97J60 MCUs

Microchip Technology Inc. has announced a family of small 8bit microcontrollers with an integrated IEEE 802.3-compliant Ethernet communications peripheral. The PIC18F97J60 device family is optimized for embedded applications and has an on-chip PHY and medium access controller (MAC). By integrating a 10BASE-T Ethernet controller onto a 10MIPS PIC18 microcontroller with up to 128Kbytes of Flash program memory, the company said it is providing embedded systems designers a single-chip remote-communication solution for a wide range of applications.

Embedded designs engineers have wanted to add remote monitoring and communication to their embedded designs, but previous solutions were expensive and complex. The integration of the company's proprietary PIC18 high-end 8bit microcontroller with complete Ethernet controller, including MAC, PHY and transmit/receive RAM buffer, promises designers a network connectivity in 64- to 100-pin packages. The company said the device is a cost-effective and easy-to-use Ethernet solution. The company is offering a free TCP/IP software stack to reduce development time.

"The need to access embedded applications remotely using Ethernet can be fully realised through the selection of the PIC18F97J60 family," said Mitch Obolsky, VP 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."

The nine-member family of PIC18F97J60 is designed for various applications in industrial automation, building automation, commercial automation and home control.

All members of the PIC18F97J60 8bit microcontroller family offer a dedicated 8KByte Ethernet buffer for efficient packet storage, retrieval and modification, and reduced memory requirements for integrated microcontroller. They also have 128KByte of Flash and 4KByte SRAM to accommodate TCP/IP stack with Web server and ample space for user-application code.

With seamless migration, the devices allow flexibility to add Ethernet connectivity on existing PIC18 designs with minimal cost and development time. It also provides reliable packet-data transmission/reception based on IEEE 802.3 with its 10BASE-T MAC and PHY.

All PIC18F97J60 devices are RoHS-compliant and are available for general sampling and volume production for 10,000-unit quantities. PIC18F97J60/96J65/96J60 are in 100-pin TQFP, PIC18F87J60/86J65/86J60 are in 80-pin TQFP and PIC18F67J60/66J65/66J60 are in 64-pin TQFP.

The PIC18F97J60 2 Development Board (part # DM163024) is available to speed development with these new microcontrollers. Microchip's suite of development tools is compatible with this new family of microcontrollers, including the MPLAB VDI visual device initializer, Application Maestro software, MPLAB ICD 2 in-circuit debugger and the MPLAB C18 C compiler.
