Fujitsu Semiconductor America Inc. extends its portfolio of general-purpose, 32bit microcontrollers (MCUs) by introducing 52 new products designed for home appliances, office automation, and digital consumer products.

The MCUs are part of the Fujitsu FM3 family of controllers announced last November. The Fujitsu FM3 devices, which are built around the ARM Cortex M3 global-standard core, incorporate a variety of peripheral features refined during Fujitsu's years of experience developing its 32bit RISC (FR) microcontrollers.

The 52 new products are part of the MB9A310 and MB9A110 Series, bringing the FM3 Basic Product Group to a total of 60 products. Coupled with the devices previously released in the High-Performance Line, the entire FM3 family now includes a total of 96 MCUs to meet a range of system design needs.

The FM3 family offers superior design freedom along with cost-performance for applications such as home appliances, audio/video equipment, portable electrical goods, factory equipment, medical products, and office automation products.

The MCUs in the FM3 Basic Product Group expand pin, memory and interface options. The 52 new devices provide flash memory from 64KBC512KB and increase the range of package options from 64-pin to 112-pin versions. A USB 2.0 host/function has also been added.

The FM3 family can operate on a range of power supply voltages, from 2.7VC5.5V. The devices are well-suited for the conventional 5V power-supply voltage needs of major home appliances, office automation devices, and other consumer electronics designed for Asia and Latin America. As part of the High-Performance Line, the new Basic Product Group devices balance sophisticated 32bit processing and performance with reduced power consumption.

The microcontrollers are embedded with high-speed, high-reliability NOR flash memory, which is designed for 100,000 write cycles and can retain data for up to 20 years. The high-speed CPUs and flash memory provided in the FM3 series have no wait-cycle penalty up to 40MHz and achieve maximum performance in this category.

In addition to maintaining the existing peripheral functions from the FR microcontroller family in the new versions, Fujitsu also implemented a wide variety of peripheral macros to meet the needs for high-precision motor control.

For example, the FM3 devices are equipped with three high-precision and high-speed independent 12bit A/D converters (2LSB 1.0us conversion), enabling fine-tuned motor control. The potential of this design can be demonstrated when the FM3 MCUs are employed in high-precision, high-speed servo motors, such as factory automation applications.

The MB9AF31xx family is available now in 112-pin BGA; 100-, 80- and 64-pin LQFP; and 100-pin QFP packages. Unit pricing for the MB9AF314NPMC starts at $5.00 each in sample quantities.
