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 ...
