F2MC-8L MB89940 Series
MB89943/P945/PV940
s OUTLINE
The MB89940 series is specially designed for automotive instrumentation applications. It features a combination
of two PWM pulse generators and four high-drive-current outputs for controlling a stepping motor. It also contains
two analog inputs, two PWM pulse generators and 10-digit LCD controller/driver for various sensor/indicator
devices. The MB89940 series is manufactured with high performance CMOS technologies and packaged in a
48-pin QFP.
s FEATURES
• 8-bit core CPU; 4 MHz system clock (8 MHz external, 500 ns instruction cycle)
• 21-bit watchdog timer
• Clock generator/controller
