1 / 27 page 62911HKPC 20110412-S00001 No.A1953-1/27 Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer 's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer 'sproductsor equipment. Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.). The products mentioned herein shall not be intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee thereof. If you should intend to use our products for applications outside the standard applications of our customer who is considering such use and/or outside the scope of our intended standard applications, please consult with us prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. LC75839PW Overview The LC75839PW is 1/4 duty and 1/3 duty general-purpose microprocessor-controlled LCD driver that can be used in applications such as frequency display in products with electronic tuning. In addition to being able to drive up to 208 segments directly, the LC75839PW can also control up to 4 general-purpose output ports. 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 208 segments When 1/3-duty: Capable of driving up to 159 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 port function. (Support for up to 4 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. • 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. • 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 : ENA1953 • CCB is a registered trademark of SANYO Semiconductor Co., Ltd. • CCB is SANYO Semiconductor's original bus format. All bus addresses are managed by SANYO Semiconductor for this format. CMOS IC 1/4 and 1/3-Duty General-Purpose LCD Display Driver |
