DATA SHEET MOS INTEGRATED CIRCUIT µ PD161602A/B 360/396-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 64-GRAY SCALES) DESCRIPTION The µ PD161602A/B is a source driver for TFT-LCDs supporting 64 gray-scale display and can operate with a supply voltage of 2.5 V for the logic block and 5.0 V for the driver block. Data input as 6-bit x 3-dot digital data is output as 64 γ -corrected values using an internal D/A converter and 5 external power modules, thus achieving a 260,000-color (full-color) display. In addition, the difference with A articles and B articles is only a difference in γ compensation resistance. FEATURES • CMOS level input • 360/396 outputs • Input of 6 bits (gray-scale data) by 3 dots • Capable of outputting 64 values by means of 5 external power modules and a D/A converter • Output dynamic range: VSS2 to VDD2 • High-speed data transfer: fCLK = 15 MHz MAX. (internal data transfer speed when operating at VDD1 = 2.5 V) • Level inversion γ -correction power supply is possible • Logic power supply voltage (VDD1): 2.2 to 3.6 V • Driver power supply voltage (VDD2): 4.5 to 5.5 V ★ ORDERING INFORMATION Part Number Package µ PD161602AP Chip µ PD161602BP Chip Remark Purchasing the above chip entail the exchange of documents such as a separate memorandum or product quality, so please contact one of our sales representatives.

PIN FUNCTIONS (1/2) Pin Symbol Pin Name Pad No. I/O Description S1 to S396 Driver output 1 to 396 Output The D/A converted 64-gray-scale analog voltage is output. Osel = L: S1 to S396 Osel = H: S19 to S378 D00 to D05 Display data input 477 to 472 D10 to D15 Input The display data is input with a width of 18 bits, viz., the gray scale data (6 bits) by 3 dots (1 pixels). DX0: LSB, DX5: MSB Input These refer to the shift direction control input. The shift directions of the shift registers are as follows. <When in Osel = L> R,/L = L (left shift): STHL (input), S396 → S1 → STHR (output) R,/L = H (right shift) : STHR (input), S1 → S396 → STHL (output) <When in Osel = H> R,/L = L (left shift): STHL (input), S378 → S19 → STHR (output) R,/L = H (right shift) : STHR (input), S19 → S378 → STHL (output) 471 to 466 D20 to D25 442 to 437 R,/L Shift direction control input 429 STHR Right shift start 498 pulse input/output I/O STHL Left shift start 410 pulse input/output I/O CLK Shift clock input 443 Input This pin is the shift clock input of the shift register. Display data is captured into the data register at the rising edge. Osel = L: The start pulse output enters high level at the rising edge of the 132 th clock following the start pulse input, and becomes the start pulse of the next level driver. The 133th clock of the first driver becomes the start pulse input of the next driver Osel = H: The start pulse output enters high level at the rising edge of the 120th clock following the start pulse input, and becomes the start pulse of the next driver. The 121th clock of the first driver becomes the start pulse input of the next driver. STB Latch input 436 Input A timing signal that latches the contents of the data register. When an H level is read at the rising edge of CLK, the contents of the data register are latched and transferred to the D/A converter, and analog voltage corresponding to the display data is output. Also, because the internal operation via CLK continues even after the STB latch, do not stop CLK. The contents of the shift register are cleared at the rising edge of STB. Following a 1-pulse input at startup, this IC will operate normally. Note that the output switch is turned off at the rising edge of STB. For the STB input timing, refer to Switching Characteristics Waveform. POL Polarity inversion signal 434 Input This pin inverts the output polarity. The polarity inversion signal data is captured at the rising edge of STB. The γ -resistor is switched in accordance with the positive/negative polarity. POL = L: Negative polarity POL = H: Positive polarity INV Data inversion 465 Input This pin inverts the input data. Input data in synchronization with the shift clock. INV = L: Normal input INV = H: Data inversion input VCOM COM amplitude output 409 These refer to the start pulse I/O pins when driver ICs are connected in cascade. Fetching of display data starts when H is read at the rising edge of CLK. R,/L = H (right shift): STHR input, STHL output R,/L = L (left shift): STHL input, STHR output Output This pin inverts the signal input from the POL pin and outputs it following conversion to the VDD2 potential at the rising edge of STB. When the VCOM output is not used, VCsel must be fixed to L.

When the VCOM output is not used, VCsel needs to be fixed to L. VCsel = L: VCOM output fixed to L VCsel = H: VCOM signal output in correspondence with POL signal CM 8-color display mode switching 433 Input The operating mode is switched to 8-color mode. In this mode, turn off the γ resistor, amplifier, and BIAS circuit. However, when the γ -correction power supply is input externally, the γ -circuit current will flow continuously. CM = L: Normal display mode CM = H: 8-color display mode AP Output SW ON/OFF 435 Input This pin turns ON/OFF the BIAS circuit and turns on the output SW and amplifier. When AP is H, the amplifier is set and the LCD is driving. The amplifier output and output SW are turned on at the rising edge of AP, starting the LCD drive. Note that the output SW is turned off at the rising edge of STB and the output becomes Hi-Z. For the AP input timing, refer to Switching Characteristics Waveform. GAM External γ usage selection 432 Input When the γ -correction power supply is input externally, switch GAM to H. If two or more chips are used, be sure to input the γ -correction power supply externally. Figure 4–1 shows an input example of the γ -correction power supply.

RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE). Consequently, a γ -correction power supply does not have to be input externally when a single source-driver chip is being used in the panel. Multiple chips can also be used without having to input a γ -correction power supply externally because the error between the chips can be absorbed by shorting the γ -correction power supply pins, as shown in Figure 4–2.

A chart indication the recommended timing of inputting the AP signal vis-a-vis the STB signal is shown below. STB AP Hi-Z MIN. 10 µs Amp driving 10 to 15 µs SW driving Note that the ideal AP signal high period differs depending on the load of the liquid crystal. The AP period must therefore be able to be adjusted using a controller. The AP signal can also be used as shown below. However, in these cases, be sure to perform sufficient evaluation before use. <When SW drive in not used> Only the amp is driven (SW drive is not used) if one horizontal period is short (40 µs or less) or the liquid crystal load is large (50 pF or more). STB AP <When the AP signal high period is 10 µs or less> The amp drive period is shortened and the SW drive period lengthened when one horizontal period is long (100 µs or more) and the liquid crystal load is small (20 pF).

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. Data Sheet S15381EJ1V0DS 23
