6 / 28 page LH1562 6 FUNCTIONAL DESCRIPTION Pin Functions (Segment mode) SYMBOL FUNCTION VDD Logic system power supply pin, connected to +2.5 to +5.5 V. V0L, V0R V12L, V12R V43L, V43R V5L, V5R Bias power supply pins for LCD drive voltage • Normally use the bias voltages set by a resistor divider. • Ensure that voltages are set such that VSS ≤ V5 < V43 < V12 < V0. •ViL and ViR (i = 0, 12, 43, 5) must connect to an external power supply, and supply regular voltage which is assigned by specification for each power pin. DI7-DI0 Input pins for display data • In 4-bit parallel input mode, input data into the 4 pins, DI3-DI0. Connect DI7-DI4 to VSS or VDD. • In 8-bit parallel input mode, input data into the 8 pins, DI7-DI0. • Refer to "RELATIONSHIP BETWEEN THE DISPLAY DATA AND LCD DRIVE OUTPUT PINS" in Functional Operations. VSS Ground pin, connected to 0 V. Control input pin for output of non-select level • The input signal is level-shifted from logic voltage level to LCD drive voltage level, and controls the LCD drive circuit. • When set to VSS level "L", the LCD drive output pins (Y1-Y240) are set to level V5. • When set to "L", the contents of the line latch are reset, but the display data are read in the data latch regardless of the condition of . When the function is canceled, the driver outputs non-select level (V12 or V43), then outputs the contents of the data latch at the next falling edge of the LP. At that time, if removal time does not correspond to what is shown in AC characteristics, it can not output the reading data correctly. • Table of truth values is shown in "TRUTH TABLE" in Functional Operations. Clock input pin for taking display data • Data is read at the falling edge of the clock pulse. XCK L/R Input pin for selecting the reading direction of display data • When set to VSS level "L", data is read sequentially from Y240 to Y1. • When set to VDD level "H", data is read sequentially from Y1 to Y240. • Refer to "RELATIONSHIP BETWEEN THE DISPLAY DATA AND LCD DRIVE OUTPUT PINS" in Functional Operations. LP Latch pulse input pin for display data • Data is latched at the falling edge of the clock pulse. |
