Toshiba America Electronic Components, Inc. (TAEC) announced availability of the TMPM370 microcontroller (MCU). This 32-bit MCU is designed for use in high-efficiency AC motor applications such as washing machines, refrigerators and air conditioners. The device combines an 80MHz ARM Cortex-M3 processing core with a hardware vector engine, providing enough computation capability to drive two independent motors. The TMPM370 is said to be the first ARM Cortex-M3 processor-based MCU to include a hardware vector engine. It is also the first of Toshiba's 5 V family of ARM Cortex-M3 processor-based MCUs for industrial and home appliance control, offering good noise immunity and simple interfacing to 5 V logic. According to the company, the TMPM370 MCU cuts the CPU load in half by offloading most of the heavy calculation to the vector engine, which also handles many of the timing tasks, such as collecting samples from ADCs and directing inputs to the PWM circuits, giving it enough compute power and real-time control capacity to handle two motors simultaneously.
