Members of the M4K and M4M groups are based on an Arm Cortex-M4 processor core with floating point unit (FPU). Operating up to 160 MHz (203 DMIPS), they feature up to 256 KB code flash, 32 KB data flash and 4 KB of user flash. Each of these devices include Toshiba’s original motor control IP, which enables sensorless field oriented control (FOC) of up to three motors via a single microcontroller device. M4K and M4M devices are supplied in LQFP packages. The microcontrollers of the M4M group include an additional CAN controller enabling direct connectivity to the commonly used industrial field bus.
M4G and M4N group devices are optimised for complex data processing. The integrated Arm Cortex-M4 processor core with FPU operates at up to 200 MHz (254 DMIPS). The devices provide integrated code flash of up to 2 MB and a separated 32 KB data flash. Featuring A-PMD IP for motor control, they are housed in both LQFP and BGA type packages - thereby offering the best fit for both industrial and consumer applications. The M4N group devices additionally include a USB 2.0 Full-Speed OTG controller with integrated PHY (up to 2 ports), a 10/100 Ethernet MAC and a CAN controller.
