■ DESCRIPTION
The MB89860/850 series has been developed as a general-purpose version of the F2MC*-8L family consisting 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 a variety of peripheral functions such as a timer unit, PWM timers, a UART, a serial interface, a 10-bit A/D converter, and an external interrupt.
The MB89860/850 series is applicable to a wide range of applications from welfare products to industrial equipment, including portable devices.

■ FEATURES
• Various package options
   QFP package (80 pins): MB89860
   SDIP package (64 pins): MB89850
• 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)
