MB89W637

* High-speed operating capability at low voltage
* Minimum execution time: 0.4 m s@3.5 V, 0.8 m s@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.
* Five types of timers
   8-bit PWM timer: 2 channels (Also usable as a reload timer)
   8-bit pulse-width count timer (Continuous measurement capable, applicable to remote control, etc.)
   16-bit timer/counter
   21-bit timebase timer
* UART
   CLK-synchronous/CLK-asynchronous data transfer capable (6, 7, and 8 bits)
* Serial interface
   Switchable transfer direction to allows communication with various equipment.
* 10-bit A/D converter
   Start by an external input 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.)
   Subclock mode
   Watch mode
* Bus interface function
   With hold and ready function
