Fujitsu indicated a year ago its plan to introduce Cortex-M3 based microcontrollers which it will aim at industrial applications.
The family is divided into the high-performance MB9BF500/400/300/100 series for the 32-bit market and the lower performance MB9AF100 series for the 16-bit market.
The MB9BF500/400/300/100 series microcontrollers can respond with zero wait-states up to 60MHz. In addition, through its high-speed 12-bit A/D converter (1.0?s), as well as its various timers, USB2.0 Host/Function, CAN, and ability to operate with a range of power supplies (2.7V to 5.5V).
The microcontrollers include embedded NOR flash memory, which is designed for 100,000 write cycles and can retain data for up to 20 years.
In particular, equipped with a high-precision and high-speed, 3-unit, 12-bit A/D converter (+/-2 lsb, 1.0?s conversion) on up to 16 channels, the microcontroller’s high-precision sampling enables fine-tuned motor control and demonstrates its true potential when employed with high-precision, high-speed servo motors and other equipment in factory automation applications.
The FM3 family includes a motor rotational position sensing counter, enabling automatic detection and making it possible to reduce the CPU workload.
Samples are available with volume to ramp in January 2011.
