Fujitsu Semiconductor has announced 32bit reduced instruction set computing microcontrollers based on the ARM Cortex M3 processor core. They are designed for processing-intensive system controllers and communications-oriented systems, with CAN and USB2.0 functionality as well as the two-channel Ethernet-media access control.
The microcontroller increases the clock rate from 80 to 144MHz. The flash memory ranges from 512kB to 1MB, and packaging is available in 176 and 144pin 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 at 144MHz CPU clock frequency.
According to the company, the microcontrollers are suitable for networked applications, including industrial systems equipment, inverter controllers, servomotor controllers, building energy Management system, home energy management system and other eco-management equipment.
The microcontrollers inherit the peripheral function set of FR microcontrollers. It provides multi function timers with waveform generator for power supply generation and a high-speed 12bit ADC. With three independent ADC units and up to 32-channels, motor-phase precision is suitable for fine-grained control. The microcontrollers feature up to three motor control blocks and offer sufficient CPU performance to control three brushless DC or permanent magnet synchronous motors.
