■ DESCRIPTION
The MB89670/A series has been developed as a line of proprietary 8-bit, single-chip microcontrollers.
In addition to the F2MC*-8L CPU core which can operate at low voltage but at high speed, the microcontrollers contain pheripheral functions such as timers, a serial interface, an A/D converter, a UART, an up/down counter, and an external interrupt.
The MB89670/A series is applicable to a wide range of applications from welfare products 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 (MB89670A: 12 channels)
    8-bit PWM timer: 3 channels (MB89670A: 6 channels) (also usable as a reload timer)
    16-bit timer/counter
    21-bit time-base 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)
• Two serial interfaces
    8-bit synchronized serial: 1 channel (Switchable transfer direction allows communication with various equipment.)
    UART: 1 channel (with 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
    8-channel input
• 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
