Toshiba launches single-chip microcontrollers
Vendor's TXZ family of high-speed, low power consumption microcontrollers incorporate the ARM Cortex -M core
Toshiba Electronics Europe has developed a new range of microcontrollers that allow a single-chip, with a low pin-count (32 to 64 pins), to control multiple motors.
The MK4 group is the second offering in Toshiba's TXZ family of high-speed, low power consumption microcontrollers that incorporate the ARM Cortex -M core.
The new MCUs meet the need to reduce energy and save space in motor control applications ranging from home appliances such as washing machines and refrigerators to power tools, ventilation fans, electric bicycles and industrial motion control.
Until now, driving two motors typically required an MCU in a 100-pin type package. Toshiba's 64-pin TXZ family products, however, can control two motors thanks to the ability to detect motor position via an integrated, high-speed AD converter with a 0.5μs conversion speed.
The new devices are based on the ARM Cortex -M4F operating at up to 80MHz and incorporating a floating point processing unit. Toshiba said the devices feature high-speed flash memory with 80MHz operation, a co-processor for Toshiba's original vector engine, and 3-channel op-amps with selectable gain. Together, they ensure the new products realise efficient motor control while improving the power factor and system control.
