FUNCTION

Used as power supply pin for digital circuit, connected to +3.0 to +5.5 V.

Used as power supply pin for analog circuit, connected to +3.0 to +5.5 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".

Used as data input pins of R, G, and B colors. 6-bit data are input from data pins at the

rising edge of CK. For relation between input data and output voltage values, refer to

"Output Voltage Value". Select the data to be entered into X, Y, and Z according to

picture element arrays of the panel.

Used as input pin for selecting the number of LCD drive outputs (309 outputs or 300 outputs).

When "L" is entered, it is 309-output mode. When "H" is entered, it is 300-output mode.

This pin is pulled up at the inside.

Used as LCD drive output pins which output the voltage corresponding to the data input

pins (XI0 to XI5, YI0 to YI5, ZI0 to ZI5).

When 300-output mode, 9 output pins (XO51 to XO53, YO51 to YO53, ZO51 to ZO53) are

invalid. Invalid output pins must be opened.

Data of XO1 to XO103 correspond to XI0 to XI5. Data of YO1 to YO103 correspond to YI0 to

YI5, and data of ZO1 to ZO103 correspond to ZI0 to ZI5.

For relation between input data and output voltage values, refer to "Functional Operations"

and "Output Voltage Value".
