Toshiba's TX04 MCUs target home appliances, industrial apps

Posted: 02 Feb 2015 ?? ?Print Version ?Bookmark and Share


Toshiba America added two new devices to its TX04 series of microcontrollers (MCUs) based on the ARMCortex-M4F processor. The TMPM470FDFG and TMPM475FDFG are designed for operation in home appliances, factory automation systems and industrial applications.

"In recent years, we have seen growing demand for motors in home appliances and factory automation systems to consume less power," said Deepak Mithani, senior director, Mixed-Signal Business Unit, System LSI Group at TAEC. "To achieve this objective requires improved vector control performance for highly effective motor control."

The TMPM470FDFG and TMPM475FDFG can operate at up to 120MHz, and both MCUs incorporate two modules, each containing a programmable motor driver, 12bit AD converter and Vector Engine (VE) technology, a hardware-based vector control processor for motor control applications that offers effective motor control together with low component count and power consumption. As a result, each has the ability to provide efficient single-chip operation of two DC brushless motors simultaneously.


In addition, the TMPM475FDFG incorporates a controller area network (CAN) controller. Required for factory automation systems, the CAN controller supports a wide range of usability, from home appliances to industrial applications.

Both MCUs come housed in a 14mm x 14mm LQFP100 package with 0.5mm pitch, and each incorporates a high-speed interactive pulse width modulator, a 10-channel 16bit timer, and direct memory access. The devices operate at 4.5V to 5.5V and feature 512KB Flash and 34KB SRAM internal memories.

Sample shipments of the TMPM470FDFG and TMPM475FDFG MCUs will commence in February, with mass production set to begin in the third quarter of 2015.
