TXZ4 Series

Single-Chip Microcontrollers Realizes Multiple Motor Control

• Two motors can be controlled with a 64-pin package.^[1]
  Until now, driving two motors required a product^[2] with a 100-pin type package. Now, the TXZ family products with 64-pin type package can control two motors, because the AD convertor for detecting motor positions is accelerated and a 0.5 μs conversion speed is realized.
• Providing solutions for driving motors more simply
  Driving motors can be easily realized by providing solutions such as sample software using built-in hardware resources (the advanced vector engine plus (A-VE+), a high-speed AD convertor, and an advanced programmable motor control circuit (A-PMD)) for realizing the vector control and the power supply control.
• The package line-up supports reductions in the size of circuit boards used for products such as home appliances.
  Provide various line-ups of pin-count (32 pins to 64 pins) and Flash memory (64 KB to 256 KB) products.
  Products with a wide pitch for flow mounting and a fine pitch for reflow mounting are included in the line-up.

Motor microcontroller for 3 motors synchronous control at 160-MHz drive

• Capable of 3-motor control
  160-MHz drive CPU and 3 AD converters and 3 advanced programmable motor control circuits (A-PMD) for motor control are incorporated, enabling easy realization of 3-motor control.
• Advanced programmable motor control circuit (A-PMD) enables simple realization of interleaved PFC control
  - The interleaved PFC control function can be realized simply by 3-phase PWM output with 120-degree phase difference.
  - Especially suitable for the ICCM (interleaved current continuous mode) requiring output capacity.
• Incorporating high-resolution advanced encoder (A-ENC32) suitable for AC servo motor
  The A-ENC32 circuit allows direct input of the signals of an incremental encoder and a hole sensor. Moreover, the accuracy of the position detection angle is improved by setting 32-bit width of encoder count values.
  Therefore, this circuit can be applied to the servo motor control.

• Appliances with a motor control system
  (Air-conditioners, washing machines, refrigerators, ventilation fans, ceiling fans, power tools, robotics, etc.)
