Fujitsu Launches a New Set of Versatile 32-bit Microcontrollers Based on ARM Cortex-M3 Technology

New MCUs Extend Fujitsu FM3 Series for Household, Office, Industrial Applications; Feature Low-Power ICs with Flash for Battery-Powered Products

SUNNYVALE, Calif., Oct. 29, 2012 — (PRNewswire) — �Fujitsu Semiconductor America today added 93 new versatile devices to its rapidly expanding FM3 family of 32-bit microcontrollers based on the ARM® Cortex™-M3 core.

The 93 new products are divided into two groups. The Basic Group has a total of 72 products that include the MB9B520M/320M/120M Series. The controllers operate at 72MHz and have been designed for inverter control, making them ideal choices for household appliances, office automation equipment, and industrial equipment.

The Basic Group MCUs are equipped with two independent, 26-channel, high-speed, 12-bit ADCs, which can convert data within one microsecond simultaneously. The microcontrollers incorporate a quadrature decoder for motor rotation control, CAN, USB 2.0, and a real-time clock, along with other standard microcontroller peripherals. Flash memory is available from 96KB to 288KB. Packaging options range from 48-pin to 96-pin configurations, including the space-saving 6x6mm 96-pin BGAs.

Low Power Group Offers Wide Range of Power-Saving Modes

The second set, the Low Power Group, features 21 new ICs in the MB9A150R Series. Power requirements are as low as 0.2 mA per MHz (40MHz operation with the peripheral clock stopped). Through clock-gating and power-gating technology, the series can be set to six different power-saving modes: sleep mode, timer mode, RTC mode, stop mode, deep standby RTC mode, and deep standby stop mode. Current consumption can be reduced depending on the usage specifications, such as to 14μA when the RTC mode is employed for date and time management, or to 2.0μA when deep standby RTC mode is used with the internal SRAM power source switched off.

The MB9A150R Series also features enhanced Flash memory and higher pin counts than prior members of the group, with Flash memory from 288KB to 544KB. The series includes peripheral functions such as a real-time clock and HDMI-CEC. The devices meet the design requirements for low power consumption while maintaining optimal CPU performance in consumer devices such as battery-powered mobile products, digital home appliances, and healthcare products. The series also supports AV applications for controlling digital connectivity between digital consumer and AV electronics systems. Package choices range from 80 to 120 pins.

With the addition of the 93 new devices, the Fujitsu FM3 family of MCUs based on the ARM Cortex-M3 processor core now includes 463 products that support a wide range of customer applications.

Pricing and Availability

The new, low power MCUs are available now in BGA and LQFP packages with prices starting at $2.78 each in 10,000-piece units. The new members of the Basic Group of MCUs in BGA or LQFP packages will be available in production quantities in late November, with prices starting at $2.25 each in 10,000-piece units.
