Toshiba Electronics Europe has introduced seven new 32-bit microcontrollers for both industrial and consumer equipment, featuring Arm Cortex-M4 cores, adding to the company's existing motor control MCU lineup.
The microcontrollers are suited for field-oriented control (FOC) of up to two AC motors, brushless DC (BLDC) motors, and multiple types of inverter control which includes a range of frequencies and drives.
Seven devices come as part of this release, featuring CPU cores and a floating-point unit (FPU) along with a memory protection unit (MPU), an internal oscillator of 10MHz (±1%), and a DMA controller (DMAC). This offers functional blocks for field-oriented control of BLDC and PMSM motors. Advance-programmable motor drives (A-PMD), advanced encoders 32-bit (A-ENC32), and high-speed/high-resolution 12-bit analogue/digital converters also help provide field-oriented control.
Adding to this, the devices feature UART, TSPI, and I²C for integrated general communication interfaces. Self-diagnosis functions have been installed onto the microcontrollers to better protect flash memory, RAM, ADC, and Clock. This allows designers to achieve IEC 60730 Class B functional safety certification.
Six of the seven released to the market make up the new M4K group, included in Toshiba’s TXZ+ Family of MCUs. This range of microcontrollers can reach speeds of up to 120MHz with flash memory options of 128KB or 256KB and 18KB of RAM. Operating at a voltage range of 2.7V to 5.5V is the operational amplifier (OPAMP), available at 0.5mm pitch LQFP64, 0.5mm pitch LQFP48, and 0.8mm pitch LQFP44.
The seventh and final new microcontroller adds to Toshiba’s M470 group, included in the TX04 Series. It operates up to 160MHz and supports firmware over-the-air updates with its 1MB flash memory. It operates on a voltage range of 4.5V to 5.5V and comes in a 0.5mm pitch LQFP100 package.
