Embedded Wi-Fi® in PIC® Microcontroller Designs Enabled by Microchip Technology with ZeroG Wireless-Based Development Tools

Explorer 16 Development Kit and PICtail(TM) Daughter Board Available Now from microchipDIRECT; Enable Wi-Fi Wireless Networks Using 8-, 16- or 32-bit PIC MCUs

CHANDLER, Ariz., June 9, 2009 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced from the Sensors Expo in Chicago the immediate availability of the ZeroG Wireless ZG2100M and ZG2101M Wi-Fi® Modules, ZeroG IEEE 802.11 Development Kit for Explorer 16 (part # AC164136) and the ZeroG Wi-Fi PICtail(TM)/PICtail Plus Daughter Board (part # AC164136-2) at www.microchipDIRECT.com, and through the Microchip sales team. Microchip and ZeroG Wireless, Inc. signed a multi-year, non-exclusive deal, which began with a joint engineering program to develop an optimized Wi-Fi solution for embedded designers and resulted in modules for Microchip's 8-, 16- and 32-bit PIC® microcontrollers (MCUs) and dsPIC® Digital Signal Controllers (DSCs). The agreement ensures long-term compatibility and availability of this joint solution.

The ZeroG Wireless "Wi-Fi I/O" (ZG2100M and ZG2101M) is an easy-to-implement, low-power, low-system-cost Wi-Fi solution that provides Wi-Fi connectivity for nearly any electronic device. The new Microchip development tools are based on the standard Microchip PICtail(TM) and PICtail Plus daughter-board connectors, which allow a designer to easily plug Wi-Fi connectivity into a variety of Microchip development kits. These kits allow easy development with the 8-bit PIC18, 16-bit PIC24 and 32-bit PIC32 MCUs, as well as the dsPIC DSCs using the broad Microchip development tools and MPLAB® Integrated Development Environment.

"We have watched the Wi-Fi market continue to grow, and have correspondingly seen an increase in our customers' requests for an embedded Wi-Fi solution," said Steve Caldwell, director of Microchip's RF Products Division. "ZeroG Wireless has developed an embedded Wi-Fi product that meets the needs of PIC microcontroller designers, and our tools make it easy to integrate."

"Partnering with Microchip to develop and distribute a highly optimized solution for their customers has provided us with an opportunity to directly reach thousands of customers who would like to 'just add Wi-Fi' to their embedded design," said Tim Colleran, vice president of marketing, ZeroG Wireless. "Microchip is a leader in the embedded market, and we feel our unique business model has provided us with the opportunity to team with such leaders."

The ZeroG Wi-Fi PICtail/PICtail Plus Daughter Board (part # AC164136-2) is available today for $59.99, and consists of the ZeroG ZG2100M FCC and Wi-Fi certified module. This daughter board allows designers to quickly create a direct connection to the Internet by seamlessly connecting to standard wireless access points. In managing the connection, the ZeroG ZG2100M module controls the MAC and baseband layers, and is connected to the host MCU or DSC via an SPI port. The 8/16/32-bit PIC MCU or dsPIC DSC that resides on the Microchip development board controls the free Microchip TCP/IP networking stack and runs the system application. Additional key features of the daughter board include:

o FCC, IC and ETSI Certified, providing considerable cost savings and quick time to market

o Wi-Fi Certified and IEEE 802.11b Compliant wireless solution

o ZG2100M small-footprint module with integrated antenna, MAC, baseband, RF and power amplifier

o Microchip's free TCP/IP stack supports standard suite of Internet Protocols

o Supports WEP, WPA and WPA2 security protocols

The ZeroG IEEE 802.11 Development Kit for Explorer 16 (part # AC164136) is available today for $189.99. This kit demonstrates 802.11 Wi-Fi connectivity using the separately available Explorer 16 development board, which supports all of Microchip's 16-bit PIC24 MCUs, 32-bit PIC32 MCUs and dsPIC DSCs. Everything you need to connect and begin development with the Explorer 16 is contained within the kit, including:

o ZeroG Wi-Fi PICtail/PICtail Plus Daughter Board

o Pre-programmed PIC24FJ128GA010 Plug-in Module for the Explorer 16, with TCP/IP and Web server application

o Pre-configured wireless broadband router

The ZeroG ZG2100M and ZG2101M Wi-Fi transceiver modules are also available today for $31.95 each in single-unit quantities. The modules provide a complete Wi-Fi wireless connection with full FCC, ETSI, IC and Wi-Fi certification, which reduces the overall design risk, eliminates design and certification cost, and enables quick time-to-market for customers wanting to add Wi-Fi to their PIC microcontroller-based products.
