OKI ML7246 is a 2.4 GHz IEEE802.15.4 Wireless device with a full speed USB 2.0 Interface

 

The ML7246 reduces packaging and development costs and contributes power savings for use in IEEE802.15.4 based USB dongles by integrating the USB interface directly into the MAC/PHY device. This targets the device for remote control and sensor network markets.  Mass production shipments of the device will begin in January 2008.

 

The ML7246 features a Full Speed USB 2.0 interface and a IEEE802.15.4 compliant 2.4GHz RF, PHY and MAC on a single chip.  By offering all these functions in a single chip, the ML7246 enables mass market adoption of IEEE802.15.4 to personal computing platforms.

 

Full-speed USB2.0 interface, HID class

Since the device enumerates as a HID class device driver, which is a standard on PCs, it eliminates the need to install a specific device driver for products based on this device.

 

Includes a power-saving function

The ML7246 includes unique capabilities which allow a PC in "standby" mode to "wake-up" to the normal PC mode when specific frames are received from another device in it's network.  This function allows users to enable power saving standby mode when there is no communication; thereby saving power for the overall system.

 

OKI will continue to enhance its wireless LSI product lineup focusing on ZigBee® for short-range wireless equipment and IEEE802.15.4 for the remote control, sensor network and ubiquitous network markets.
