The FM3 Family combines the Cortex-M3 core with peripheral functions developed for the FR microcontrollers. The addition of the 54 products in the High Performance Group brings the FM3 Family to a total of 160 products to suit every application. Fujitsu plans to continue expanding the line. Further FM3 Family members, including Low Power products, will be added until end of 2011 and in 2012

Ramping up the clock rate from 80 MHz used in existing products in the High Performance Group to 144 MHz dramatically increases processing capacity. In addition to previously-offered ancillary functions, the new products also include two channels each for Ethernet-MAC, USB2.0 and CAN.
Flash memory ranges from 512KB up to 1MB, and packaging in 176-pin and 144-pin alternatives.
The high-speed onboard flash memory operates up to 72MHz without wait states. Together with the flash accelerator, zero wait state operation is possible even at 144 MHz CPU clock frequency,
These products are ideal for applications that demand high-speed processing, including system controllers, office equipment, motor control or programmable controllers for automated factory equipment.
Features of the High Performance Group: MB9BD10/610/510/410/310/110 Series
1. Higher performance with high-speed flash memory
The new additions to this group have dramatically increased processing performance. The access speed of reliable, fast NOR-type flash memory allows read operations with no wait time, and this high-speed memory access results in class-leading processing capacity that makes the most of the CPU’s innate performance. The new products inherit the reliability of their predecessors, handling 100,000 write operations and 20-year retention performance.
2. Dramatically strengthened communications functions, Ethernet-MAC support newly added
The new products in the group bring greatly expanded communications functions, including a new 2-channel Ethernet-MAC controller, as well as 2-channel USB2.0 host functionality (MB9BF610), 2-channel CAN (MB9BFD10/510/410). This makes them ideal for a wide range of networked applications, including industrial systems equipment, inverter controllers, servomotor controllers, BEMS/HEMS and other eco-management equipment, and office equipment. With built-in support for IEEE1588, these products can be used for time-synced communications between factory automation applications
3. Runs on wide range of operating voltages for maximum power-supply compatibility
The FM3 family runs on operating voltages ranging from 2.7V to 5.5V. The 5V range is preferable for power supplies in factory equipment as is more resistant to noise, and likewise for use in control equipment and motor controllers, which are often used in noisy environments.
4. Ancillary macro set implements high-precision motor control
These new products inherit the peripheral function set of FR microcontrollers, which have an established reputation for motor control. In particular, sophisticated multi function timers with waveform generator for PWM generation and a high-speed 12-bit A/D converter is effective for use in high-precision, high-speed servomotors and the like. With three independent ADC units and up to 32 channels, motor-phase precision is improved for very fine-grained control. Multiturn capable quadrature decoders process encoder signals in hardware and unburden the CPU from calculating the rotor position. The new FM3 Microcontrollers feature up to 3 motor control blocks and offer sufficient CPU performance to control 3 brushless DC or PMS (permanent magnet synchron) motors.
