PRELIMINARY PRODUCT INFORMATION MOS INTEGRATED CIRCUIT µPD161644 241 OUTPUT GATE DRIVER WITH POWER SUPPLY FOR TFT-LCD GATE DRIVER DESCRIPTION The µPD161644 is a TFT-LCD gate driver with power supply for TFT-LCD driver. Because this gate driver has a level shift circuit for logic input, it can output a high gate scanning voltage in response to a CMOS-level input. This ICs can generate the levels which TFT-LCD driver need, from 2.7 V. FEATURES • High breakdown voltage output (VDD1-VSS3 = 40 V MAX.) • 2.7 V CMOS level input • Number of output: 241 output selectable • To generate 4 levels from single voltage input • To integrate regulator circuit for source driver • Mode setting from source driver: Serial I/F or pin control • On-chip VCOM driver • On-chip gate output low-level selector ORDERING INFORMATION Part number Package µPD161644P Chip Remark Purchasing the above chip entails the exchange of documents such as a separate memorandum or product quality, so please contact one of our sales representatives.

When COMSEL is set to 1, directly input the VCOM center voltage to the VOMIN pin from outside the IC. 30 COMSEL VCOM center adjustment 0 Internal D/A is valid (R31 setting is valid). 1 VCOMIN input voltage is valid.

SERIAL INTERFACE When the serial interface has been selected, if the chip is active (GCS = L), serial data input (GDA) and serial clock input (GCL) can be received. Serial data is read from D7 and then from D6 to D0 on the rising edge of the serial clock, via the serial input pin. This data is synchronized on the eighth serial clock's rising edge and is then converted to parallel data for processing. The serial interface signal chart is shown below. Figure 10-1.

Remarks 1. The shift register and counter are reset to their initial values when the chip select signal is inactive. Do not set the chip select signal to inactive between transmission of an 8-bit command and transmission of the 8bit data set for the command. 2. When using GCL wiring, take care concerning the possible effects of terminating reflection and noise from external sources. We recommend checking operation with the actual device. 36 Preliminary Product Information S15797EJ1V4PM µPD161644 11.

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. Preliminary Product Information S15797EJ1V4PM 51
