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.
