Optimized for primary control of consumer equipment and industrial equipment, and motor control

  • Arm Cortex-M3 core, operating at up to 120MHz
    • Based on the industry de facto standard Arm Cortex-M core.
  • Wide range of memory and package lineup
    • 256 to 1024KB code flash and 32KB data flash with 100k write cycles endurance
    • The Products with built-in 1MB code flash allows instructions to be read from one area, while the updated code is programmed into the other area in parallel by two separate areas of 512KB.
    • 64 to 128KB SRAM with parity and 2KB backup RAM
    • Package line-up (64 to 144pin) 
  • Various built-in interfaces and motor control for motors, home appliances, and Industrial equipment.
    • Programmable motor driver for optionally controlling brushed or brushless motor and encoder interface.
    • Digital-to-analog converter
    • 12bit Analog-to-digital converter, selectable from two sample hold time for each analog input pin
    • Built-in digital LCD controller supports easy contrast adjustment, saves on the bill of materials, and eases PCB routing.
    • 2.7 to 5.5V voltage and -40 to 105˚C operating temperature suitable for a variety of general motor control and HMI applications, both for consumer and industrial equipment.
    • Self-diagnosis functions supporting functional safety certification according to various standards (IEC 60730 class B and others)
  • Built-in high-speed oscillator, equipped with oscillation accuracy +/-1% (operating temperature -40 to 105˚C)
    By improving the oscillation accuracy, the number of parts can be reduced by eliminating the need for an external oscillator.
  • Both code flash and data flash are rewritable up to 100,000 times
    By high level resilience to repeated data write and erase.


  • For the main control of consumer equipment (home appliances, toys, health care equipment etc.) and office equipment (multi-function printers, etc.)
  • For the motor control of consumer equipment, industrial equipment
  • For IoT of consumer equipment, industrial equipment, etc.
