Toshiba Electronics Europe offers 12 new motor control MCUS in its M4K series of devices. This is the first product in the new advanced TXZ+ family. In addition, the company also announced that they are beginning volume production of an additional 10 motor control MCUS in the M4M group. All the new devices are manufactured using a 40nm process and form part of the TXZ4A+ family.
These devices include an advanced programmable motor driver (A-PMD), 32-bit advanced encoder (A-ENC), an advanced vector engine (A-VE+), and up to three high-speed and high-resolution channel 12-bit ADCs. Therefore, these devices are well suited for FOC with up to three AC motors, BLDC motors, and various types of inverter controls such as variable frequency drives or servo drives. All of these products are based on the ARM Cortex-M4 kernel with FPU and MPU and run at up to 160MHz.
MCU provides onboard flash memory (128kB/256kB) of code and 32kB of data, as well as 24kB of plain RAM and DMAC. It contains the sum of six 32-bit timers, which can be operated to 12 16-bit timers if needed. The analog portion has a 12-bit ADC with up to 22 input channels and 3 op-amp channels.
This set of devices includes multi-channel UART, SPI, and I2C interfaces for general purpose communication, while the M4M group also has a CAN communication interface. Both groups offer ROM, RAM, ADC and clock self-diagnostic capabilities, and all the new motor control MCUS offer complex functionality while providing low current consumption and maintaining good backward compatibility with existing TXZ M4K(2) products.
These products are available in various fine-pitch surface mount LQFP packages with up to 100 pins in sizes as small as 10mm x 10mm.
Each device comes with comprehensive documentation, software samples with practical usage examples, driver software, and evaluation boards with control interfaces for each peripheral. In addition, a development environment is provided to assist in the design and development process in collaboration with global ecosystem partners.
