Toshiba: TXZ+ Family Advanced Class, Arm Cortex-M4 Microcontrollers for Motor Control (Graphic: Business Wire)
These products use Arm Cortex-M4 core with FPU, running up to 160MHz, and integrating motor control circuit A-PMD (advance-programmable motor driver), 32-bit encoder A-ENC (advanced-encoder) and vector engine A-VE+ (advanced vector engine plus). These devices provide suitable solutions for AC motor, brushless DC motor and various inverter controls with a maximum of three units of high-speed and high-resolution 12-bit analog/digital converters.
Devices in the M4K group have UART, SPI and I2C integrated as general communication interfaces, and the M4M group additionally has a CAN communication interface. Both groups have self-diagnosis functions for ROM, RAM, ADC and clock, which help the customer achieve IEC60730 Class B functional safety certification. Both groups achieve low current consumption and high functionality while maintaining good compatibility with existing TXZTM family M4K(2) group.
Documentations, sample software with example of actual usage, evaluation boards and driver software which control interfaces for each peripheral are provided together with parts shipment. A development environment is also provided to support various needs in cooperation with global Arm ecosystem partners.
