67.5MHz. Test Pattern of power supply current
a. Typ: Black pattern
b. Max: Dot pattern
2. The lamp frequency should be selected as different as possible from the horizontal synchronous
frequency and its harmonics to avoid interference, which may cause line flow on the display
3. The voltage above this value should be applied to the lamps for more than 1 second to start-up.
Otherwise the lamps may not be turned on.

4.0 OPTICAL SPECIFICATIONS
4.1 Overview
The test of Optical specifications shall be measured in a dark room (ambient luminance 1 lux and
temperature = 25±2°C) with the equipment of Luminance meter system (Goniometer system and
TOPCON BM-5) and test unit shall be located at an approximate distance 50cm from the LCD surface at
a viewing angle of θ and φ equal to 0°. We refer to θφ=0 (=θ3) as the 3 o’clock direction (the “right”),
θφ=90 (=θ12) as the 12 o’clock direction (“upward”), θφ=180 (=θ9) as the 9 o’clock direction (“left”)
and θφ=270 (=θ6) as the 6 o’clock direction (“bottom”). While scanning θ and/or φ, the center of the
measuring spot on the display surface shall stay fixed. The measurement shall be executed after 30
minutes warm-up period. VDD shall be 5.0V +/- 10% at 25°C. Optimum viewing angle direction is 6
o’clock.

Note:
1. Viewing angle is the angle at which the contrast ratio is greater than 10. The viewing are determined
for the horizontal or 3, 9 o’clock direction and the vertical or 6, 12 o’clock direction with respect to
the optical axis which is normal to the LCD surface.
2. Contrast measurements shall be made at viewing angle of θ= 0° and at the center of the LCD surface.
Luminance shall be measured with all pixels in the view field set first to white, then to the dark
(black) state. (See FIGURE 1 shown in Appendix) Luminance Contrast Ratio (CR) is defined
mathematically.
CR = Luminance when displaying a white raster
Luminance when displaying a black raster
3. Center Luminance of white is defined as the LCD surface. Luminance shall be measured with all
pixels in the view field set first to white. This measurement shall be taken at the locations shown in
FIGURE 2 for a total of the measurements per display.
4. The White luminance uniformity on LCD surface is then expressed as :
Luminance of five points / Minimum Luminance of five points (See FIGURE 2 shown in appendix).
5. The color chromaticity coordinates specified in Table 4. shall be calculated from the spectral data
measured with all pixels first in red, green, blue and white. Measurements shall be made at the center
of the panel.
6. The electro-optical response time measurements shall be made as FIGURE 3 shown in Appendix by
switching the “data” input signal ON and OFF. The times needed for the luminance to change from
10% to 90% is Td, and 90% to 10% is Tr.
7. Cross-Talk of one area of the LCD surface by another shall be measured by comparing the
luminance (Y
(Y
) of that same area when any adjacent area is driven dark. (See FIGURE 4 shown in Appendix).

9.0 POWER SEQUENCE
To prevent a latch-up or DC operation of the LCD module, the power on/off sequence should be as
shown in below.
0 < T1 10 ms
20ms < T2 50 ms
500 ms T3
100 ms T4
0 < T5 50 ms

Notes:
1. When the power supply VDD is 0V, Keep the level of input signals on the low or keep high
impedance.
2. Do not keep the interface signal high impedance when power is on.
3. Back Light must be turn on after power for logic and interface signal are valid.

12.0 HANDLING & CAUTIONS
12.1 Cautions when taking out the module
Pick the pouch only, when taking out module from a shipping package.
12.2 Cautions for handling the module
As the electrostatic discharges may break the LCD module, handle the LCD module with
care. Peel a protection sheet off from the LCD panel surface as slowly as possible.
As the LCD panel and back-light element are made from fragile glass material, impulse and
pressure to the LCD module should be avoided.
As the surface of the polarizer is very soft and easily scratched, use a soft dry-cloth without
chemicals for cleaning.
Do not pull the interface connector in or out while the LCD module is operating.
Put the module display side down on a flat horizontal plane.
Handle connectors and cables with care.
12.3 Cautions for the operation
When the module is operating, do not lose LVDS signals. If any one of these signals were
lost, the LCD panel would be damaged.
Obey the supply voltage sequence. If the wrong sequences were applied, the module would be
damaged.
12.4 Cautions for the atmosphere
Dewdrop atmosphere should be avoided.
Do not store and/or operate the LCD module in a high temperature and/or humidity
atmosphere. Storage in an electro-conductive polymer-packing pouch and under relatively
low temperature atmosphere is recommended.
12.5 Cautions for the module characteristics
Do not apply fixed pattern data signal to the LCD module at aging time.
Applying fixed pattern for a long time may cause image sticking.
12.6 Other cautions
Do not disassemble and/or re-assemble LCD module.
Do not re-adjust variable resistor or switch etc.
When returning the module for repair or etc, please pack the module not to be broken. We
recommend on using the original shipping packages.

1.1 General Description
The M6759 is an 8032/8052 instruction compatible 8-bit microcontroller with MTP Flash ROM for
firmware updating. By combining a versatile 8-bit CPU with MTP-Flash, this device provides whole
microcontroller system on one chip and still remains the feasibility for general control systems in a
variety of applications. Furthermore, user-defined security registers can protect the firmware after
the code is ready.
The M6759 contains the following:
a. A non-volatile 64K bytes Multiple Times Programmable ROMprogram memory.
b. A volatile 512 bytes read/write data memory
c. Four 8-bit I/O ports, two 16-bit timer/event counters (identical to the timers of the 80C51)
d. A 16-bit timer (identical to the Timer 2 of the 8052).
e. A multi-source two-priority-level nested interrupt structure.
f. One serial interface (UART) and
g. An on-chip oscillator.

2.2 Pin Description Table
Pin assignments shown below are listed based on 44-pin PLCC package. And if not additionally
specified, further pin number reference throughout this datasheet is, by default, referred to 44-pin PLCC
package. As for the QFP package, the pin number assignment should be shifted accordingly, as
comparatively shown in Section 2.1 Pinout Diagram.

Multiplexed address/data bus. During the time when ALE is high, the
I/O
LSB of a memory address is presented. When ALE falls, the port
transitions to a bi-directional data bus. This bus is used to read external
ROM and read/write external RAM memory or peripherals.
Reset signal of internal circuit, it must be kept 4 clocks to ensure being
recognized by internal circuit. This signal will not affect internal
SRAM.
Program Store Enable Output, commonly connected to external ROM
memory as a chip enable during fetching and MOVC operation. /PSEN
goes high during a reset condition.
from multiplexed address/data bus, commonly connect to the latch
enable of 373 family. This signal will be forced high when the device is
in a reset condition.
Port 1 is 8 bits bi-directional I/O port with internal pull high. All pins
I/O
have an alternate function shown as below.
IN External timer/counter 2 trigger.
IN External timer/counter 2.
I/O Port 2 is 8 bits bi-directional I/O port with internal pull high. The
alternate function is MSB 8 bit address bus
OUT This bus emits the high-order address byte during fetches from external
Program Memory or during accesses to external Data Memory that use
16-bit addresses (MOVX @ DPTR).
During accesses to external Data Memory that use 8-bit addresses
(MOVX @ Ri), Port 2 emits the contents of the P2 Special Function
Register.
