General Description
The NT7701 is a 160-bit output segment/common driver LSI suitable for driving the large scale dot matrix LCD panels used by PDA's, personal computers and work stations for example. Through the use of SST (Super Slim TCP) technology, it is ideal for substantially decreasing the size of the frame section of the LCD module. The NT7701 is good as both a segment driver and a common driver, and a low power consuming, high-precision LCD panel display can be assembled using the NT7701. In the segment mode, the data input is selected 4bit parallel input mode or as 8bit parallel input mode by a mode (MD) pin. In common mode, the data input/output pins are bi-directional and the four data shift directions are pin-selectable.

Functional Description
1. Block description 1.1. Active Control In the case of segment mode, controls the selection or deselection of the chip. Following a LP signal input, and after the select signal is input, a select signal is generated internally until 160 bits of data have been read in. Once data input has been completed, a select signal for cascade connection is output, and the ship is deselected. In the case of common mode, controls the input/output data of bidirectional pins. 1.2. SP Conversion & Data Control In the case of segment mode, keep input data which are 2 clocks of XCK at 4-bit parallel mode into latch circuit, or keep input data which are 1 clock of XCK at 8-bit parallel mode into latch circuit, after that they are put on the internal data bus 8 bits at a time. 1.3. Data Latch Control In the case of the segment mode, it selects the state of the data latch, which reads in the data bus signals. The shift direction is controlled by the control logic and for every 16 bits of data read in, the selection signal shifts one bit, based on the state of the control circuit. 1.4. Data Latch In the case of the segment mode, it latches the data on the data bus. The latched state of each LCD driver output pin is controlled by the control logic and the data latch control 160 bits of data are read in 20 sets of 8 bits. 1.5. Line Latch / Shift Register In the case of the segment mode, all 160 bits which have been read into the data latch, are simultaneously latched on to the falling edge of the LP signal, and output to the level shift block. In the case of the common mode, shifts data from the data input pin on to the falling edge of the LP signal. 1.6. Level Shifter The logic voltage signal is level-shifted to the LCD driver voltage level, and output to the driver block. 1.7. 4-Level Driver It drives the LCD driver output pins from the line latch/shift register data, selecting one of 4 levels (V0, V12, V43, VSS) based on the S/C, FR and DISPOFF signals. 1.8. Control Logic It controls the operation of each block. In the case of the segment mode, when an LP signal has been input, all blocks are reset and the control logic waits for the selection signal output from the active control block. Once the selection signal has been output, operation of the data latch and data transmission are controlled, 160 bits of data are read in, and the chip is deselected. In the case of the common mode, it controls the direction of the data shift.

7. Precaution Be careful when connecting or disconnecting the power This LSI has a high-voltage LCD driver, so it may be permanently damaged by a high current, which may occur, if a voltage is supplied to the LCD driver power supply while the logic system power supply is floating. The details are as follows: ! ! When connecting the power supply, connect the LCD driver power after connecting the logic system power. Furthermore, when disconnecting the power, disconnect the logic system power after disconnecting the LCD driver power. We recommend that you connect a serial resistor (50-100) or fuse to the LCD driver power V0 of the system as a current limiting device. Also, set a suitable value for the resistor in consideration of the LCD display grade.
In addition, when connecting the logic power supply, the logic condition of the LSI inside is insecure. Therefore connect the LCD driver power supply after resetting logic condition of this LSI inside on DISPOFF function. After that, the DISPOFF cancel the function after the LCD driver power supply has become stable. Furthermore, when disconnecting the power, set the LCD driver output pins to level VSS on the DISPOFF function. After that, disconnect the logic system power after disconnecting the LCD driver power. When connecting the power supply, follow the recommended sequence shown.

Cautions concerning storage: 1. When storing the product, it is recommended that it be left in its shipping package. After the seal of the packing bag has been broken, store the products in a nitrogen atmosphere. 2. Storage conditions : Storage state Storage conditions Temperature: 5 to 30; humidity: 80%RH or less unopened (less than 90 days) 3. 4. 5. 6. After seal of broken (less than 30 days) Room temperature, dry nitrogen atmosphere Don't store in a location exposed to corrosive gas or excessive dust. Don't store in a location exposed to direct sunlight of subject to sharp changes in temperature. Don't store the product such that it is subjected to an excessive load weight, such as by stacking. Deterioration of the plating may occur after long-term storage, so special care is required. It is recommended that the products be inspected before use.
