Toshiba Releases Arm® Cortex®-M4 Microcontrollers for Motor Control as First Products in the TXZ+TM Family Advanced Class
July 29, 2021
Toshiba Electronic Devices & Storage Corporation
TOKYO—Toshiba Electronic Devices & Storage Corporation ("Toshiba") has started the mass production of 12 new devices in the M4K group for motor control as the first products of the TXZ+TM family advanced class, and will start mass production of another 10 products in the M4M group in August 2021. Both the M4K and M4M groups of microcontrollers will be manufactured in a 40nm process, and belong to the TXZ4A+ series.
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.
Major features of new products
- High performance Arm Cortex-M4 core with FPU, max 160MHz
- Motor and inverter control functions and communication interfaces
- Self-diagnosis functions for IEC60730 class B functional safety
Applications
Motor control for consumer home appliances and industrial equipment.
