■ DESCRIPTION
The MB89810A series is a line of single-chip microcontrollers based on the F2MC*-8L CPU core which can operate at low voltage but at high speed. The microcontrollers contain peripheral function such as timer, serial interface, a UART, and an external interrupt. The MB89810A series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

■ FEATURES
High speed processing at low voltage
Minimum execution time: 0.8 µs/3.0 V, 1.33 µs/2.2 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.
• Four types of timers
    8-bit PWM timer: 2 channels (also serve as reload timers)
    16-bit timer/counter
    21-bit time-base timer
• Two serial interface
    8-bit synchronous serial (Switchable transfer direction allows communication with various equipment.)
    UART (5-, 7-, or 8-bit transfer capable)
• External interrupt: 8 channels
    Eight 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)
