HD61602

HD61602 / HD61603 (Segment Type LCD Driver) 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 such as the HMCS6800 series. 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. Features Wide-range operating voltage — Operates in a wide range of supply voltage: 2.2 V to 5.5 V — Compatible with TTL interface at 4.5 V to 5.5 V Low current consumption — Can run from a battery power supply (100 µA max. at 5 V) — Standby input enables standby operation at lower current consumption (5 µA max. on 5 V) Internal power supply circuit fo...
