LC75835W
Overview
1/3, 1/4-Duty General-Purpose LCD Display Driver
The LC75835W is a 1/3, 1/4 duty general-purpose LCD display driver that can be used for displaying segments for mobile devices and other such products under the control of a microcontroller. In addition to being able to directly drive up to 136 LCD segments, the LC75835W can also control up to 16 general-purpose output ports. It incorporates an oscillation circuit that reduces the external resistors and capacitors used for oscillation.
Features
* Either 1/4 or 1/3 duty can be selected with the serial control data. 1/4 duty drive: Up to 136 segments can be driven 1/3 duty drive: Up to 105 segments can be driven * Either 1/3 or 1/2 bias can be selected with the serial control data. * On, off, or blinking for each segment can be set with the serial control data. * Serial data control of display switching in 40-bit units. (As a general rule, the display can be switched in 12 segment-units.) * Serial data control of current on/off to the LCD drive bias voltage generation divider resistors. * 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 functions. * Buzzer control signals (1 channel) can be 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 the segment blinking frequency. * Serial data control of switching between the internal oscillator operating mode and external clock operating mode. * Serial data input supports CCB* format communication with the system controller. * Independent VLCD for the LCD driver block (VLCD can be set to any voltage in the range 2.7 to 5.5 volts without regard to the logic block power supply VDD). * The INH pin allows the display to be forced to the off state. * Incorporation of an oscillator circuit

Notes: PCn = "1": "H" (VLCD) is output from output pin Pn (n = 1 to 16). PCn = "0": "L" (VSS) is output from output pin Pn (n = 1 to 16). If, for instance, output pins S4/P4 and S5/P5 have been selected as the general-purpose output ports at PC4 = "1" and PC5 = "0", "H" (VLCD) is output from output pin P4 and "L" (VSS) is output from output pin P5. 2. PS1 to PS16: Segment output port/general-purpose output port switching control data This control data is used to switch between segment output ports and general-purpose output ports for the S1/P1 to S16/P16 output pins.

If, for instance, PS1 to PS3 = "0", PS4, PS5 = "1" and PS6 to PS16 = "0", general-purpose output ports are selected for output pins S4/P4 and S5/P5 and segment output ports are selected for output pins S1/P1 to S3/P3 and S6/P6 to S16/P16. 3.

The INH pin and Display Control
Since the IC internal data (1/4 duty: the display data D1 to D272 and the control data, 1/3 duty: the display data D1 to D210 and the control data) is undefined when power is first applied, applications should set the INH pin low at the same time as power is applied to turn off the display (This sets the S1/P1 to S16/P16, S17 to S34, COM1 to COM3, and COM4/S35 to the VSS level.) and during this period send serial data from the controller. The controller should then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at power on. (See Figures 5 and 6.)
Notes on the Power On/Off Sequences
Applications should observe the following sequences when turning the LC75835W power on and off. (See Figures 5 and 6) * At power on: Logic block power supply (VDD) on LCD driver block power supply (VLCD) on * At power off: LCD driver block power supply (VLCD) off Logic block power supply (VDD) off However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off at the same time. 1. 1/4 duty

Notes on Controller Transfer of Display Data
Since the LC75835W accepts the display data (D1 to D272) divided into 12 separate transfer operations when using 1/4 duty drive scheme and data (D1 to D210) divided into 9 separate transfer operations when using 1/3 duty drive scheme, we recommend that the applications transfer all of the display data within a period of less than 30ms to prevent observable degradation of display quality.
Generation of Buzzer Control Signal
A square wave with a 50% duty ratio is output from the general-purpose output port selected for the output of the buzzer control signal between the start and end of the buzzer control signal output. If, for example, general-purpose output port P1 has been selected as the output of the buzzer control signal (PC1 = "0", PS1 = "1"), the waveform shown below will be output.

Oscillation Stabilization Time of the Internal Oscillation Circuit
It must be noted that the oscillation of the internal oscillation circuit is unstable for a maximum of 100s (oscillation stabilization time) after oscillation has started.
