NUMMICRO ML56 series low -power micro -controllers of NUMMMICRO ML56 series are based on the 1T 8051 core, embedded 64 KB Flash and 4 KB SRAM, built -in capacitance touch key, and running as high as 24 MHz. In normal operation mode, the operation rate of low power operation is less than 100 μl a/MHz. When the LCD panel is displayed, the power drop current is lower than 2µA. The operating voltage of the ML56 series is 1.8 V to 3.6 V, and -40 ° C to+105 ° C.
The Nummitro ML56 series of integrated capacitance touch circuits, enhanced the touch key controller, supports up to 14 independent touch channels, has the characteristics of low power consumption characteristics and waterproof, high noise resistance. The touch key can be used as one of the sources of awakening, and 10 VRMS anti -noise is performed, which is especially suitable for home appliances and industrial control.
ML56 series built -in 4 COM X 32 SEG, 6 COM X 30 SEG, 8 COM X 28 SEG LCD controller, which can drive up to 224 points and support type A and B LCD panels. It provides two VLCD input sources, one is an external voltage and the other is the internal charge pump. The internal charge pump keeps the constant voltage of VLCD to maintain the display quality of the LCD panel when VDD input changes. VLCD has two driving modes, external capacitance mode and internal resistance mode. The external capacitance mode with strong driving current supports large -size panels, and the inner resistance mode drives small size panels to reduce power consumption.
