■ DESCRIPTION
The MB89850R series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit, single-chip microcontrollers.

■ FEATURES
• Various package options
    SDIP package (64 pins)/QFP package (64 pins)
• High-speed processing at low voltage
    Minimum execution time: 0.4 µs/3.5 V, 0.8 µs/2.7 V
• 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.
• 8-bit PWM timers: 2 channels
    Also usable as a reload timer
• UART
    Full-duplex double buffer
    Synchronous and asynchronous data transfer
• 8-bit serial I/O
    Switchable transfer direction allows communication with various equipment.
• 10-bit A/D converter
    Conversion time: 13.2 µs
    Activation by an external input or a timer unit capable
• External interrupt: 4 channels
    Four channels are independent and 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.)
• Bus interface functions
    Including hold and ready functions
• Timer unit
    Outputs non-overlap three-phase waveforms to control an AC inverter motor.
    Also usable as a PWM timer (4 channels)
