Fujitsu Semiconductor has added a new 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 also introducing a new FM0+ family of devices based on the Cortex-M0+ core.
The Fujitsu FM3 family, introduced in 2010, now includes 463 products. With the introduction of the FM4 and FM0+ families, Fujitsu is offering more than 700 ARM-based devices.
FM4 Family Features FPUs, SDRAM and SD Card Interfaces, Flash Memory, New Package Options
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. These features make the FM4 products ideal for motor controls and network controls in factory automation applications, as well as for inverters and other industrial equipment.
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.
“Because these new products feature the latest three types of Cortex-M series processor cores, customers can select products to suit a broader range of applications,” said Akio Nezu, senior manager of marketing at Fujitsu Semiconductor America. “Designers can utilize the enhanced scalability of each core to smoothly transition from low-end to high-end equipment, or vice-versa.”
Availability: 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.
