Toshiba Releases Arm Cortex-M4 Microcontrollers for Motor Control

Toshiba TXZ 400x275

July 28, 2021

Toshiba Electronic Devices & Storage Corp. has announced the start of mass production of 12 new devices in the M4K Group for motor control, the first products in the TXZ+ family advanced class. The company said it will start mass production of another 10 products in the M4M Group in August 2021. Both groups of microcontrollers will be manufactured in a 40nm process, and belong to the TXZ4A+ series, Toshiba said.

The products use Arm Cortex-M4 cores with FPU, running up to 160MHz and integrating motor control circuit A-PMD (advanced programmable motor driver), 32-bit encoder A-ENC (advanced encoder) and vector engine A-VE+ (advanced vector engine plus). Toshiba said the devices provide suitable solutions for AC motor, brushless DC motor and several inverter controls with a maximum of three units of high-speed and high-resolution 12-bit analog/digital converters.

The company added that 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 can self-diagnose for ROM, RAM, ADC and clock, which help customers achieve IEC60730 Class B functional safety certification. Both microcontroller groups can achieve low current consumption and high functionality while maintaining compatibility with existing TXZ-family M4K(2) group.

Included with the parts are documentation, sample software with examples of actual usage, evaluation boards and driver software that control interfaces for each peripheral. Toshiba said a development environment is also provided to support various needs in cooperation with global Arm ecosystem partners.

The company said applications for the microcontroller include robots, motor control for consumer home appliances, industrial equipment, air conditioners, washing machines, general-purpose inverters, and power conditioners.
