Fujitsu Microelectronics Launches Mobile WiMAX Chipsets for Mobile Devices
- Designed to fit in WiMAX modules sized 12 x 12mm, features standby current of less than 0.5mA -
Tokyo, June 16, 2008 - Fujitsu Microelectronics Limited (FML) announced today a new
mobile WiMAX chipset optimized for mobile WiMAX devices such as smart phones and
PDAs. Sample shipment will start in August 2008. The chipset includes a baseband LSI,
the MB86K22; an RF LSI, the MB86K52; and a power management LSI, the MB39C316.
The three devices are essential elements for competitive WiMAX modules. The chipset
was designed so that the size of the WiMAX module will be 12x12mm. The standby
current - which has a direct impact on battery life - will not exceed 0.5mA, facilitating the
development of attractive mobile WiMAX terminals.
technology will be deployed in the
United States, Europe, and Taiwan this
year, and in Japan next year. The initial
service will be through PC-based mobile
broadband access, with simultaneous
development of handsets, smart phones,
PDAs, portable games and navigation
The chipset's mature software stacks
have been proven in the previous
generation product, and the power
management schemes have been
optimized at the system level. These
factors enable mobile WiMAX terminal
manufacturers to focus on designing
service-oriented applications.

"This highly integrated WiMAX chipset features the low power and small form factor
essential to the development of attractive mobile WiMAX terminal products," said
Makoto Awaga, General Manager of the Mobile Solution Business Group of Fujitsu
Microelectronics Limited in Japan. "Fujitsu Microelectronics has assumed a global
leadership position in moving WiMAX into deployment, and we are now ready to work
with module vendors to meet market requirements."
Chipset Key Features
The MB86K22 is a fully integrated baseband LSI built using Fujitsu Microelectronics'
65nm advanced CMOS low-leakage process technology. The operating power of the
MB86K22 has been reduced by 36 percent from the previous generation. Power-gating
technology shuts down the power supply in the unused blocks inside the device, so that

the entire mobile WiMAX module consumes only 0.5mA, thereby extending battery life.
The MB86K52 is an RF LSI built using CMOS process technology, which supports
2.3GHz, 2.5GHz, and 3.5GHz, almost all the frequencies set by the WiMAX Forum. This
offers mobile WiMAX terminal manufacturers the ability to introduce global WiMAX
devices. The MB86K52 also supports MIMO and beamforming technology, which is
essential for mobile WiMAX Wave 2.
The MB39C316 power management LSI eliminates all the complex and time-consuming
power management requirements by accommodating one cell battery. This design
minimizes the peripheral components outside of the module. The MB39C316 controls
and manages the module's power schemes at the system level, achieving the lowest
power consumption at each operation.
Sample Price and Availability
Samples of Fujitsu Microelectronics' Mobile WiMAX chipset will be available in August 2008.
Sample price is 8,000 JPY
