Description
The HD61602 and the HD61603 are liquid crystal display driver LSIs with a TTL and CMOS compatible
interface. Each of the LSIs can be connected to various microprocessors.
The HD61602 incorporates the power supply circuit for the liquid crystal display driver. Using the
software-controlled liquid crystal driving method, several types of liquid crystals can be connected
according to the applications.
The HD61603 is a liquid crystal display driver LSI only for static drive and has 64 segment outputs that
can display 8 digits per chip.
