Because it has the PWM output of a maximum of 3 ch, the brightness control of the LED backlight of RGB can be done. Incorporation of an oscillation circuit helps to reduce the number of external resistors and capacitors required. Features • Support for 1/4-duty 1/3-bias or 1/3-duty 1/3-bias drive techniques under serial data control. When 1/4-duty: Capable of driving up to 272 segments When 1/3-duty: Capable of driving up to 207 segments • Serial data input supports CCB format communication with the system controller (Support 3.3V and 5V operation). • Serial data control of the power-saving mode based backup function and the all segments forced off function. • Serial data control of switching between the segment output port and general-purpose output portfunction. (Support for up to 8 general-purpose output ports) • Support for the PWM output function of a maximum of 3ch (It can output from the general-purpose output port). • Support for clock output function of 1ch (It can output from the general-purpose output port). • Serial data control of the frame frequency of the common and segment output waveforms. • Serial data control of switching between the internal oscillator operating mode and external clock operating mode. • High generality, since display data is displayed directly without the intervention of a decoder circuit. • Built-in display contrast adjustment circuit. • The INH pin allows the display to be forced to the off state. • Incorporation of an oscillator circuit (Incorporation of resistor and capacitor for an oscillation). Ordering number : ENA1687 CMOS IC 1/4, 1/3-Duty General-Purpose LCD Display Driver • CCB is ON Semiconductor® ’s original format. All addresses are managed by ON Semiconductor® for this format. • CCB is a registered trademark of Semiconductor Components Industries, LLC. |
