■ DESCRIPTION
The MB89490 series has been developed as a general-purpose version of the F2MC*-8L family consisting of proprietary 8-bit single-chip microcontrollers.

■ FEATURES
• Package used
    QFP package for MB89F499, MB89497,MB89498
    MQFP package for MB89PV490
• High speed operating capability at low voltage
• Minimum execution time: 0.32 µs/12.5MHz
• 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.
• Clock
    Embedded PLL clock multiplication circuit for sub-clock
    Operating clock (PLL for sub-clock) can be selected four times of the sub-clock oscillation
• Six timers
    PWM timer x 2
    8/16-bit timer/counter x 2
    21-bit timebase timer
    Watch prescaler
• External interrupt
    Edge detection (selectable edge) : 8 channels
    Low level interrupt (wake-up function) : 8 channels
• 10-bit A/D converter (8 channels)
    10-bit successive approximation type
• UART/SIO
    Synchronous/asynchronous data transfer capability
• SIO
    Synchronous data transfer capability
• LCD controller/driver
    Max. 32 segments output x 4 commons
• I2C interface circuit
• Remote receiver circuit
• Low-power consumption mode
    Stop mode (oscillation stops so as to minimize the current consumption.)
    Sleep mode (CPU stops so as to reduce the current consumption to approx. 1/3 of normal.)
    Watch mode (everything except the watch prescaler stops so as to reduce the power comsumption to an extremely low level.)
    Sub-clock mode
• Watchdog timer reset
• I/O ports: max. 66channels
