HD61603R
HD61602/HD61603 (Segment Type LCD Driver) Description Features 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. • 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 for liquid crystal display driver (HD61602) — Internal power supply circuit for liquid crystal display driver facilitates the connection to a microprocessor system 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.
