Fujitsu Updates Microcontroller Line

May 01, 2013

Fujitsu Semiconductor has fortified its FM3 family of 32-bit microcontrollers with 38 new products, including components for high-capacity memory, low-pin-count packaging, and low power that are optimized for controlling systems for household appliances, as well as office automation and industrial equipment, the company said.

Fujitsu launched the FM3 family -- which are RISC microcontrollers based on the ARM Cortext-M3 processor core -- in 2010. The line now has a total of 570 offerings, with the new products to begin shipping this month.

The new line-up, according to the company, is optimal for system control in household appliances, and office automation and industrial automation systems, with each of the three new microcontroller groups having their specific features and best-use cases. Specifically, Fujitsu is adding products to the Basic Group of the FM3 family, including the MB9B520T/420T/320T/120T series of microcontrollers, which are designed for high capacity with up to 1.5 MB of Flash memory. The low-pin MB9B120J series also is being added to the group; this series is available in 32-pin packaging. The company also now offers a low-power microcontroller in the new MB9A420L/120L Series, which supports CAN communications.

Each new series has specifications suited to its individual design goals and applications. The MB9B520T/420T/320T/120T Series is now the highest-memory-capacity option in the FM3 family, and also includes a multifunction timer capable of inverter control. This makes it most suitable for inverter control applications in household appliances, such as air conditioners, as well as various motors used in office automation equipment, including printers and copiers, according to Fujitsu.

Its design also is well-suited for man-machine interface control in audio-visual and automation equipment in part because its high-capacity memory allows for multiple language support in the display function of these applications, the company added.

The new MB9B120J Series has the distinction of being the first Fujitsu FM3 line-up to feature 32-pin packaging, which optimizes it for low-pin inverter control applications such as inverters and motors for low-end industrial equipment. It's also well-suited for refrigerators, washing machines, induction heating cookware, and other household appliances, as well as for devices that require a one-to-one motor to microcontroller system architecture.

Rounding out the new additions to the FM3 family is the MB9A420L/120L Series, which features CAN communications and is optimized for energy efficiency in 48-pin and 64-pin packages. This series is best suited for use in equipment that requires push button tone control, such as elevators, building management applications, and electronic switchboards, according to Fujitsu.
