MOS INTEGRATED CIRCUIT µPD16430A 1/2, 1/3, 1/4 DUTY LCD CONTROLLER/DRIVER The µPD16430A is an LCD controller/driver that enables the display of LCDs of 1/2 duty, 1/3 duty and 1/4 duty cycle. The LCD controller contained in the µPD16430A employs serial data transfer and uses an automatic increment function for data addresses which eliminates the need to set addresses newly each time. The LCD driver uses a medium voltage output (14 V max.), which enables higher contrast and a wider viewing angle.
