Fujitsu Introduces Easy-to-Use, 802.15.4 ZigBee Wireless Kit

Singapore, May 28, 2007  — Fujitsu Microelectronics Asia Pte., Ltd. (FMAL) today announced the industry’s first 2.4GHz 802.15.4/ZigBee demonstration kit aimed at making it easier for customers to add wireless control functions to existing systems. The new WiLeKit supports the IEEE 802.15.4/ZigBee standard. The kit greatly reduces the complexity of wireless ZigBee interconnections with a Fujitsu-patented simple network control protocol. Now, everyone will be able to easily add wireless functions to their applications.

Based on the IEEE 802.15.4 standard, ZigBee is a wireless communication technology for short distances (within 100m), low data rates (up to 250kbps), low power consumption (operating life from six months to two years with ordinary alkaline batteries) and high reliability. Unlike Bluetooth (802.15.1), which is used to transfer voice data, and WiFi (802.11a/b/g), which is used to transfer Email and images, the ZigBee system emphasizes multi-node monitoring, control and sensory network applications.

“Customers expect to immediately add wireless control functions into their existing systems. The market has been looking for an easy-to-use ZigBee solution,” said Andy Chang, deputy marketing director of the System LSI Business Group of Fujitsu Microelectronics Asia. “As the industry’s first ZigBee wireless solution with a simple networking protocol, Fujitsu’s WiLeKit fully meets market needs. There are almost unlimited applications for many fields, such as intelligent community systems, power substation monitoring and wireless measuring instruments.”

Today, most systems used in medium-to-small-scale corporations generally have no more than 255 nodes. Furthermore, they are individual, with no need to interact with other products or systems within the corporation. Since it is not necessary to support a complex mesh network, a simple star/tree topology network architecture is sufficient (Fig. 1). Users want to adopt a simple network control protocol without expensive certification fees and quickly implement ZigBee wireless control functions with high reliability. The WiLeKit demo kit, with its simple network control protocol, satisfies these market needs. Fujitsu Microelectronics is providing an optimal solution for this rapidly increasing market through continuous innovation.

The WiLeKit demo kit (Fig. 2) consists of five end devices and one personal area network coordinator, which allows users to build a simple network. Manual or automatic modes can be set. In manual mode, users can obtain any end field data from the network control center by simply pressing a button. In automatic mode, the end device will regularly transmit field data to the control center on its own. Whether in manual or automatic mode, all communication between the network control center and end device is full duplex and adopts a collision-avoidance transmission mechanism for talk-when-ready to guarantee data reliability.

The new wireless module contains a UZ2400 RF transceiver from UBEC Co. and a low-power, 8-bit microcontroller unit, the MB95F108A, with 60K of flash memory from Fujitsu Microelectronics Co. Fujitsu Microelectronics has a wide range of microcontroller units from 8- to 16-bit and voltages from 3V to 5V. All are available with the new kit, so users can choose products to meet their specific demands and applications.
