PPD16666A
240-OUTPUT LCD ROW DRIVER
DESCRIPTION
The PPD16666A is a row (common) driver which contains a RAM capable of full-dot LCD display. With 240 outputs, this driver can be combined with a column (segment) driver PPD16661A which contains a RAM to display VGA (640 by 480 dots), 1/2 VGA, or 1/4 VGA, etc. By combining it with the PPD16661A, the PPD16666A can provide four gray levels by frame rate control. With its built-in display RAM in the column driver, the driver kit can reduce current consumption, thus making it most suitable for the display section of a PDA or portable terminal.
FEATURES
* * * * * LCD-driven voltage: 20 to 36 V Duty: 1/240 Driving type: 2 lines selected simultaneously Output count: 240 outputs Capable of gray level display: 4 gray levels (frame rate control)

BLOCK FUNCTION
1. Liquid-crystal drive circuit This circuit selects and outputs the level for liquid-crystal driving. One of VDD, VEE, and V1 is selected by the output of the selection control circuit. 2. Selection control circuit This circuit creates the signal which will select the level of the output signal, based on the output of the shift register circuit and the driving level power selection signals L1 and L2 3. Bidirectional shift register circuit This refers to the 120-bit bidirectional shift register circuit. The DIR signal can be used to switch over the shift direction. The data that has been entered from the FRMB terminal is shifted by the row drive signal strobe (STB). 4. Level shifter circuit This circuit transforms the 5-V signals to the high-voltage signals for liquid-crystal driving.

DETAILS OF PIN FUNCTIONS
* STB (input) Refers to the input pin of the row drive strobe signal. The bidirectional shift register is shifted at STB's rising edge. * FRMB (input) Refers to the input pin of the frame signal. The shift register data is read at STB's rising edge. * DIR (input) Refers to the input pin of the drive output's shift direction selection signal. When the shift direction selection signal (DIR) is "L", the shift data (selection signal) is shifted from the drive output X1 to the X240 direction. When "H", it is shifted from the X240 to the X1 direction. * DOFFB' (input) Refers to the input pin of the display OFF signal. It is placed in the display OFF status (all outputs at V1) at the "L" level. In the mean time, it reads the frame signal and returns to the normal display status at the "H" level. * L1 & L2 (input) Refer to the input pins of the drive level power selection signal. In the case of the liquid-crystal drive output, the two lines are selected simultaneously by the shift register. L1 selects the first line, and L2 the second line. Both lines select VDD at "H", and VEE at "L".

Remark
While the DOFFB' is "L", the X output remains at the V1 level. Afterward, if it becomes "H", the level of the X output is output timed with the above timing.
Note When the time lag between STB signal and the L1, L2 signals is large, hazard may occur in output.

SYSTEM CONFIGURATION EXAMPLE
An example of configuring a liquid-crystal panel of half-VGA size (480 across by 320) by using four column drivers and two row drivers. * * * * * * Each column driver sets the LSI No. with PL0, 1, and 2 pins. The DIR pins of each column driver are all set to low level. Only one of the column drivers is set to the master; all the others are set to the slave. Signals are supplied from the master column driver to the slave column driver and to the row driver. Connect an oscillator resistor to the OSC1 and OSC2 pins on the master, and leave these pins open on the slave. All the signals from the system (D0 to D15, A0 to A16, CSB, OEB, WEB, UBEB, RDY, RESETB, and DOFFB) are connected in parallel to the column driver. Connect a pull-up resistor to the RDY signal. The TEST pin is used to test the LSI, and is open or grounded when the system is configured.

NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device before using it in a particular application. Standard: Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product.
