■OUTLINE
The MB89670R/670AR series has been developed as a line of proprietary 8-bit, single-chip microcontrollers.
In addition to the F2MC*-8L family CPU core which can operate at low voltage but at high speed, the
microcontrollers contain pheripheral functions such as timers, a serial interface, a 10-bit A/D converter, a UART, an 8/16-bit up/down counter/timer, and an external interrupt. The MB89670R/670AR series is applicable to a wide range of applications from consumer appliances to industrial equipment, including portable devices.

FEATURES
•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-speed processing at low voltage
• Minimum execution time: 0.4 µs@3.5 V, 0.8 µs@2.7 V, 2.0 µs@2.2 V
• I/O ports: max. 69 channels
• Timers: 9 channels (MB89675AR/677AR/P677A/PV670A: 12 channels)
8-bit PWM timer: 3 channels (MB89675AR/677AR/P677A/PV670A: 6 channels) (also usable as a reload
timer or 8-bit PWM timer)
16-bit timer/counter
21-bit timebase timer
8/16-bit timer (8 bits ×2 channels or 16 bits)
8/16-bit up/down counter/timer (8 bits ×2 channels or 16 bits)
• 2-channel serial interfaces
  8-bit synchronized serial: 1 channel (Switchable transfer direction allows communication with various
equipment.) UART: 1 channel (internal full-duplex double buffer)
• External interrupts: 8 channels
   Eight channels are independent and capable of wake-up from low-power consumption modes (with an edge detection function).
• Buzzer output
• 10-bit A/D converter Input: 8 channels
• 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.)
• Bus interface function
  Including hold and ready functions
