8-bit Proprietary Microcontroller

Fujitsu 

MB89140 Series

(Continued)

• Low-voltage operation (when an A/D converter is not used)

• Low current consumption (compatible with dual-clock system)

• High-voltage ports on chip

• Five types of timers

8-bit PWM timer (also usable as a reload timer)

12-bit MPG timer (also usable as a PPG output, PWM output, and reload timer)

8/16-bit timer (also usable as two 8-bit timers)

21-bit time-base timer

• One serial interface

Swichable transfer direction allows communication with various equipment.

• 10-bit A/D converter: 12 channels

Successive approximation type

• External interrupt: 2 channels

Two channels are independent and capable of wake-up from low-power consumption modes. (Rising edge,

falling edge/both edges selectability)

–0.3 V to +7.0 V can be applied to INT1 (N-ch open-drain)

• 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

• Reset output and power-on reset selectability
