Fujitsu Semiconductor America has introduced its FM4 family of 32-bit general purpose RISC microcontrollers based on the ARM Cortex-M4 processor core, featuring DSP and floating point (FPU) functions. In addition, Fujitsu is introducing a new FM0+ family of devices based on the Cortex-M0+ core. With the introduction of the FM4 and FM0+ families, Fujitsu will offer more than 700 ARM-based devices featuring a consistent architecture and maximum design flexibility, along with high performance and low power requirements.
The new FM4 family covers the highest end of the product range with DSP and FPU capabilities not available in the FM3 family. All products in the FM4 family will be equipped with the FPU, along with SDRAM and SD card interface functions. The FM4 series also features an expanded variety of packaging options as well as a wide range of timers and serial communications functions. The devices integrate high-quality and reliable flash memory technology from Fujitsu.
In addition to inverter control functions, various communication functions, CAN, USB 2.0 and Ethernet support, the FM4 family is equipped with high-speed serial communications functions and high-speed, high-performance AD converters.
The FM0+ family of energy-efficient models employs a power-efficient Cortex-M0+ core and features the peripheral functions of the FM3 family, all delivered with high-quality flash memory technology. Compared with the previous Cortex-M0 core, the Cortex-M0+ core achieves 10 percent improved processing performance while consuming just two-thirds of the power.
Functions that reduce power consumption are built into the microcontrollers, enabling the FM0+ family to target an operating current of 70μA/MHz and a standby current of just 0.7μA (in RTC mode). The low power consumption makes the new MCUs ideal for portable devices or other power-constrained applications such as battery-operated devices and electronic meters, and sensor controls.
Fujitsu plans to begin releasing sample quantities of products in these new families starting in 2013, and will begin full-scale production of these products later in the year.
