FUNCTIONAL DESCRIPTION Pin Functions
SYMBOL VCC VLS GND SPIO SPOI FUNCTION Used as power supply pin for digital circuit, connected to +2.5 to +3.6 V. Used as power supply pin for analog circuit, connected to +8.0 to +13.0 V. Used as ground pin, connected to 0 V. Used as input pins of start pulse and also used as output pins for cascade connection. When "H" is input into start pulse input pin, data sampling is started. On completion of sampling, "H" pulse is output to output pin for cascade connection. Pin functions are selected by LBR. For selecting , refer to "Functional Operations". Used as input pin for selecting the shift register direction. For selecting, refer to "Functional Operations". Used as input pin for parallel transfer from sampling memory to hold memory. Data is transferred at the rising edge and output from LCD drive output pin. Used as shift clock input pin. Data is latched into sampling memory from data input pin at the rising edge. Used as reference voltage input pins. Hold the reference voltage fixed during the period of LCD drive output. For relation between input data and output voltage values, refer to "Output Voltage Value". For internal gamma correction, refer to "Gamma Correction Value". Observe the following relation for input voltage. VLS > VH0 VH32 VH256 VL256 VL32 VL0 > GND. Used as data input pins of R, G, and B colors. 8-bit x 2-pixel data are input from data pins at the rising edge of CK. For relation between input data and output voltage values, refer to "Functional Operations" and "Output Voltage Value". Select the data to be entered into X, Y, and Z according to picture element arrays of the panel. Used as LCD drive output pins which output the voltage corresponding to the input of data XO1-XO128 YO1-YO128 ZO1-ZO128 input pins (XA0 to XA7, YA0 to YA7, ZA0 to ZA7, XB0 to XB7, YB0 to YB7, ZB0 to ZB7). Data of XO1 to XO128 correspond to XA0 to XA7 and XB0 to XB7. Data of YO1 to YO128 correspond to YA0 to YA7 and YB0 to YB7, and data of ZO1 to ZO128 correspond to ZA0 to ZA7 and ZB0 to ZB7. For relation between input data and output voltage values, refer to "Functional Operations" and "Output Voltage Value". Used as input pins for input data polarity exchange, POLA corresponds to XA0 to XA7, YA0 to YA7 and ZA0 to ZA7, and POLB corresponds to XB0 to XB7, YB0 to YB7 and ZB0 to ZB7. When "L" is entered, display data becomes normal mode. When "H" is entered, input data becomes polarity exchange mode. For relation between input data and output voltage values, refer to "Output Voltage Value". These pins are pulled down at the inside. REV Used as polarity exchange pin of LCD drive output. Date is taken at the term when LS is "H" and the output polarity of the LCD drive output pin is determined. For exchanging, refer to "Output Characteristics".

(Gamma) Correction Value
Between reference voltage input pins VH0 and VH256, 256 resistors are connected in series. And between reference voltage input pins VL0 and VL256, 256 resistors are connected in series. No resistor is connected between reference voltage input pins VH256 and VL256. The correction curve is a broken line connected between intermediate voltage inputs (VH32, VH64, VH96, VH128, VH160, VH192, VH224, VL32, VL64, VL96, VL128, VL160, VL192 and VL224). Each correction value between the intermediate voltage inputs is divided into 32 parts by resistor.

PRECAUTIONS
Precautions when connecting or disconnecting the power supply This IC has some power supply pins, so it may be permanently damaged by a high current which may flow if voltage is supplied to the LCD drive power supply while the logic system power supply is floating. Therefore, when connecting the power supply, observe the following sequence. VCC / logic input / VLS, VH0-VH256, VL0-VL256 When disconnecting the power supply, follow the reverse sequence. Reference voltage input The relation of the reference voltage input is shown here. VLS > VH0 VH32 VH224 VH256 0.5VLS VL256 VL224 VL32 VL0 > GND Maximum ratings When connecting or disconnecting the power supply, this IC must be used within the range of the absolute maximum ratings. Target output load This IC is designed for a 200 pF output load capacity. When using this IC for other than 200 pF panels, confirm the device is having no problem before using it.
