Product Summary

The AY0438-I/P is a CMOS integrated device that drives a liquid crystal display, usually under microprocessor control. The part acts as a smart peripheral that drives up to 32 LCD segments. It needs only three control lines due to its serial input construction. The AY0438-I/P latches the data to be displayed and relieves the microprocessor from the task of generating the required waveforms. The AY0438-I/P can drive any standard or custom parallel drive LCD display, whether it be field effect or dynamic scattering; 7-, 9-, 14- or 16-segment characters; decimals. The applications of the AY0438-I/P include Industrial displays, Consumer product displays, Telecom product displays, Automotive dashboard displays.
