M3H群

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 control circuits 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 supply 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.
