DESCRIPTION

MB89910A series is a line of single-chip microcontrollers using the F²MC-8L(F²MC stands for FUJITSU Flexible Microcontroller) CPU core. The microcontrollers contain a variety of peripheral functions such as 5 stage operating speed controller, VFD driver, A/D converter, Serial interface, buzzer, watch prescaler, a low voltage detection circuit and external interrupts.

FEATURES

• Minimum execution time: 0.5µs at 8 MHz
• F²MC-8L family CPU core
• Instruction set optimized for controllers
  
  • Multiplication and division instructions
  • 16-bit arithmetic operations
  • Test and branch instructions
  • Bit manipulation instructions, etc.
• High Voltage Ports (built-in a pull down resistor capable)
  
  • 8 ports for large current
  • 10 ports for small current
• Three types of timers
  
  • 8-bit PWM timer
  • 16-bit timer/counter
  • 21-bit time-base timer
• Serial interface
  
  • 8-bit synchronous serial interface (Switchable transfer direction allows communication with various equipment.)
• External interrupt: 2 channels: Capable of wake-up from low-power consumption modes (with an edge detection function)
• Low-power consumption modes
  
  • Stop mode (Oscillation stops to minimize the current consumption.)
  • Sleep mode (The CPU stops to reduce the current consumption to approx. 1/3 of normal.)
