PIN FUNCTIONS Pin Symbol Pin Name O1 to O263 Driver output R,/L Shift direction select input STVR, STVL Start pulse input/output CLK I/O Description Output These pins output scan signals that drive the vertical direction (gate lines) of a TFTLCD. The output signals change in synchronization with the rising edge of shift clock CLK. The driver output amplitude is VDD2 to VEE2. Input R,/L = H (right shift): STVR → O1 → O263 → STVL R,/L = L (left shift): STVL → O263 → O1 → STVR I/O This is the input of the internal shift register. The start pulse is read at the rising edge of shift clock CLK, and scan signals are output from the driver output pins. The input level is a VDD1 to VSS (logic level). When in MODE = H, the start pulse is output at the falling edge of the 263rd clock of shift clock CLK, and is cleared at the falling edge of the 264th clock. The output level is VDD1 to VSS (logic level). Shift clock input Input This pin inputs a shift clock to the internal shift register. The shift operation is performed in synchronization with the rising edge of this input. OE1, OE2, OE3 Output enable input Input When this pin goes high level, the driver output is fixed to VEE2 level. The shift register is not cleared. CLK is asynchronous in the clock. Note that the output terminal which can be controlled by the enable signal changes refers to 4. RELATIONS OF ENABLE INPUT AND OUTPUT TERMINAL. /AO All-on control Input When this pin goes low level, the driver output is fixed to VDD2 level. The shift register is not cleared. This pin has priority over OE1 to OE3. This pin is pulled up to VDD1 power supply inside µ PD16702. CLK is asynchronous in the clock. MODE Selection of Number of outputs Input MODE = VDD1 or open: 263 outputs MODE = VSS: 256 outputs (Outputs pins O129 to O135 are invalid in 256-output mode.) Input level is VDD1 to VSS (logic level) This pin is pulled up to VDD1 power supply inside µ PD16702. VDD1 Logic power supply – 2.3 to 3.6 V VDD2 Driver positive power supply – 15 to 25 V The driver output: high level VSS Logic ground – Connect this pin to the ground of the system. VEE1 Negative Power supply for internal operation – –15 to –5 V VEE2 Driver negative power supply – The driver output: low level (VEE2 to VEE1 < 6.0 V) Cautions 1. To prevent latch-up, turn on power to VDD1, VEE1/2, VDD2, and logic input in this order. Turn off power in the reverse order. These power up/down sequence must be observed also during transition period. 2. Insert a capacitor of about 0.1 µF between each power line, as shown below, to secure noise margin such as VIH and VIL.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
