MB89800 Series
(Continued)
• LCD controller/driver
Max 70 segments/4 commons
Divided resistor for LCD power supply
• Three types of timers
8-bit PWM timer (also usable as a reload timer)
8-bit pulse width count timer (also usable as a reload timer)
20-bit time-base counter
• Two serial interfaces
8-bit synchronous serial interface (Switchable transfer direction allows communication with various equipment.)
UART (5-, 7-, 8-bit transfer capable)
• External interrupt: 2 channels
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.)
