Fujitsu Releases New High-Performance 16-bit Microcontrollers for Notebook PCs
9/10/2002 - Fujitsu Limited announced the release of two new additions to the MB90370 series in its F2MC family of microcontrollers, the MB0F372 and MB90372. The products, 16-bit microcontrollers with built-in power management functions for use as mobile computer keyboard controllers, were developed together with the Hong Kong Design Center of Fujitsu Microelectronics Pacific Asia Limited (FMP).
Increasing demand for ever more compact notebook PCs that can deliver performance on par with desktop models has raised requirements for high-function, highly integrated devices. Fujitsu's MB93070 series is designed to respond to these needs with its integrated power-management features and wide range of interfaces.
Key advantages of the MB93070 include:
- Integrated LPC bus and serial IRQ simplify interface with host controller.
- Built-in power-management features include on-chip comparator and power control circuit for the AC power controller and battery monitor, enabling efficient control of up to three batteries.
- Includes I2C and multi-address I2C to communicate with smart batteries, which support SMBusRev 1.1 specifications for packet-error checking and timeout detection. The multi-address I2C can be set to any six addresses. A bridge circuit that can switch these communications paths is also built in.
- Phoenix Technologies' firmware will be adapted for the MB90370 series, facilitating implementation in notebook PC embedded environments.
- Fujitsu is committed to the ongoing improvement of its F2MC family of system microcontrollers, offering customers simpler system designs, lower parts counts, and reduced footprint requirements. Fujitsu is also extending its line to cover such areas as automotive, digital AV and car audio applications.
Sample pricing (excluding tax) in Japan for the MB90F372 with flash memory is 1,500 yen, and for the MB90372 with mask ROM, 750 yen. Samples will be available from October 2002. Fujitsu has set a sales target of 100,000 units per month for the two models combined.
