8-bit Proprietary Microcontroller

Fujitsu 

MB89920 Series

(Continued)

• 20-bit time-base counter

• UART: 1 channel (with asynchronous transfer mode and 8-bit synchronous serial mode)

• 8-bit serial interface: 1 channel (LSB first/MSB first selectability)

• 10-bit A/D converter: 8 channels

• LCD controller/driver: 28 segments × 4 commons (max. 112 pixels)

• Low-voltage detection reset

• Watchdog timer reset

• External interrupt: 4 channels

Four channels are independent and capable of wake-up from the low-power consumption mode (with edge

detection function)

• Buzzer output/clock output

• Low-power consumption modes:

Stop mode (The software stops oscillation to minimize the current consumption.)

Sleep mode (The CPU stops to reduce current consumption to approx. 1/3 of normal.)

Hardware standby mode (The pin input stops oscillation.)
