Spansion unveils its ARM chip line-up after Fujitsu acquisition

Spansion has announced its ARM Cortex-M series microcontroller offering following the acquisition of Fujitsu’s microcontroller business.

In August,  the flash memory chip firm paid $110m for Fujitsu’s microcontroller and analogue business. Spansion also acquired $38m of MCU inventory.

Designated the FM family, it will deliver 200MHz/250MIPS  performance for applications such as factory automation, building management and motor control. There are different voltage ranges from 1.65V to 5.5V, embedded flash memory options ranging from 64kbyte to 2Mbyte, analogue interfaces, and support for serial, CAN, USB and Ethernet communications interfaces.

“This scalable family of microcontrollers allows for differentiated features such as touch, connectivity and inverter drives to be added into a single MCU, ” said Saied Tehrani, senior vice president and CTO of Spansion.

With more than 570 products in production, the Cortex-M3 standard core based Spansion FM3 family ranges from 32-pin to 176-pins. It comes with a rich set of peripherals, including inverter drive support, USB, CAN and Ethernet, and offers 64kbytes to 1.5Mbytes of embedded Flash memory.

The Cortex-M4 based Spansion FM4 family incorporates DSP and FPU functions that provide the power required for advanced computations and eases a model-based design approach. The products include a rich set of peripherals, including inverter drive support, SDIO, USB, CAN and Ethernet, and embedded flash ranging from 256kbytes to 2Mbytes that support 100,000 rewrite cycles with a 20-year data retention.

The Spansion FM0+ family is based on the ARM Cortex-M0+ core, optimised for low power and high efficiency. With only 70μA/MHz, it offers industry leading power consumption. This family is designed for a whole range of industrial applications that require low-power consumption at cost-effective prices. The products are now sampling.
