LCD Controller/Driver Features Wide Supply Range

Operating from supply voltages ranging from 1.8V in static mode to 5.5V, the EM6111 low-multiplex controller and driver for monochrome TN and STN LCDs can drive one or two rows plus seven columns, with an integrated display refresh. All display segments can be individually turned on or off by SET or BLANK bit commands, respectively. A two-wire serial mode interface controls the circuit for initialization, memory programming, and circuit status readout. The RAM data corresponds to the LCD segments. A set bit in the RAM results in an activated segment. Other features include an operating-temperature range from -40°C to +85°C and low power consumption. Pricing starts at $0.56 each/100,000.
