, Ltd zip: 200233 Tel: 86-021-64850700 Fax: 86-021-64855865 LCD Driver for 160 Display Units BL55076 General Description The BL55076 is a peripheral device, which interfaces to almost any Liquid Crystal Display (LCD) having low multiplex rates.
It generates the drive signals for any static or multiplexed LCD containing up to four back planes and up to 40 segments and can easily be cascaded for larger LCD applications.
The BL55076 is compatible with most microprocessors/micro controllers and communicates via a two-line bi-directional IIC -bus.
Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware sub addressing and by display memory switching (static and duplex drive modes).
Features • Single-chip LCD controller/driver • Selectable back plane drive figuration: static or2, 3or 4backplane multiplexing • Selectable display bias configuration: static,1/2 or 1/3 • Internal LCD bias generation with voltage-follower buffers • 40 segment drives: up to twenty 8-segment numeric characters; up to ten 15-segment alphanumeric characters; or any graphics of up to 160 elements • 40×4-bit RAM for display data storage • Auto-incremented display data loading across device sub address boundaries • Display memory bank switching in static and duplex drive modes • Versatile blinking modes • LCD and logic supplies may be separated • 2.
5 to 6V power supply range • Low power consumption • Power saving mode for extremely low power consumption in battery-operated and telephone applications • IIC -bus interface • TTL/CMOS compatible • Compatible with any 4-bit, 8-bit or 16-bit microprocessors/micro controllers • May be cascaded for large LCD applications (up to 1536 segments possible) • Ascendable...
