7 FUNCTIONAL BLOCK DESCRIPTIONS
7.1 Command Decoder and Command Interface
This module determines whether the input data is interpreted as data or command. Data is
directed to this module based upon the input of the D/C# pin. If D/C# is high, data is written to
Graphic Display Data RAM (GDDRAM). If D/C# is low, the input at D
command and it will be decoded and written to the corresponding command register.
Reset is of the same function as Power ON Reset (POR). Once RES# receives a negative reset
pulse of about 1us, all internal circuitry will be back to its initial status. Refer to Command
Description section for more information.
7.2 MPU Parallel 6800-series Interface
The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), D/C#, E(RD#)
and CS#. R/W(W R#) input High indicates a read operation from the Graphic Display Data RAM
(GDDRAM) or the status register. R/W(WR#) input Low indicates a write operation to Display
Data RAM or Internal Command Registers depending on the status of RS input. The E(RD#)
and CS# input serves as data latch signal (clock) when they are high and low respectively.
Refer to Figure 14 of parallel timing characteristics for Parallel Interface Timing Diagram of
6800-series microprocessors.
In order to match the operating frequency of display RAM with that of the microprocessor, some
pipeline processing is internally performed which requires the insertion of a dummy read before
the first actual display data read. This is shown in Figure 3 below.

7.3 MPU Parallel 8080-series Interface
The parallel interface consists of 8 bi-directional data pins (D0 - D7), R/W(WR#), E(RD#), D/C#
and CS#. The CS# input serves as data latch signal (clock) when it is low. Whether it is display
data or status register read is controlled by D/C#. R/W(WR#) and E(RD#) input indicates a write
or read cycle when CS# is low. Refer to Figure 16 of parallel timing characteristics for Parallel
Interface Timing Diagram of 8080-series microprocessor.
Similar to 6800-series interface, a dummy read is also required before the first actual display
data read.

7.4 MPU Serial 4-wire Interface
The serial interface consists of serial clock SCK, serial data SDA, D/C# and CS#. SDA is shifted
into an 8-bit shift register on every rising edge of SCL in the order of D
sampled on every eighth clock and the data byte in the shift register is written to the Display
Data RAM or command register in the same clock. No extra clock or command is required to
end the transmission.
7.5 MPU Serial 3-wire interface
Operation is similar to 4-wire serial interface while D/C# is not been used. The Display Data
Length instruction is used to indicate that a specified number display data byte(s) (1-256) are to
be transmitted. Next byte after the display data string is handled as a command.
It should be noted that if there is a signal glitch at SCK that causing an out of synchronization in
the serial communication, a hardware reset pulse at RES# pin is required to initialize the chip
for re-synchronization.

7.6 Graphic Display Data RAM (GDDRAM)
The GDDRAM is a bit mapped static RAM holding the bit pattern to be displayed. The size of
the RAM is 104 x 65 x 2 = 13,520bits. Figure 5 is a description of the GDDRAM address map.
For mechanical flexibility, re-mapping on both Segment and Common outputs are provided.
For vertical scrolling of display, an internal register storing the display start line can be set to
control the portion of the RAM data mapped to the display. Figure 5 shows the case in which
the display start line register is set at 30H.
For those GDDRAM out of the display common range, they could still be accessed, for either
preparation of vertical scrolling data or even for the system usage.
7.7 Oscillator Circuit
This module is an On-Chip low power RC oscillator circuitry (Figure 4). The oscillator generates
the clock for the DC-DC voltage converter. This clock is also used in the Display Timing
Generator.

7.8 LCD Driving Voltage Generator and Regulator
This module generates the LCD voltage needed for display output. It takes a single supply input
and generates necessary bias voltages.
It consists of:
1. 2X, 3X, 4X and 5X DC-DC voltage converter
2. Bias Divider
If the output op-amp buffer option in Set Power Control Register command is enabled, this circuit
block will divide the regulator output (V
The divider does not require external capacitors to reduce the external hardware and pin counts.
3. Contrast Control
Software control of 64 voltage levels of LCD voltage.
4. Bias Ratio Selection circuitry
Software control of 1/4 to 1/9 bias ratio to match the characteristic of LCD panel.
5. Self adjust temperature compensation circuitry
Provide 5 different compensation grade selections to satisfy the various liquid crystal temperature
grades. The grading can be selected by software control. Defaulted temperature coefficient (TC)
value is -0.14%/°C.
) to give the LCD driving levels (VL2 - VL5).
out
7.9 169 Bit Latch
A register carries the display signal information. In 104 X 65 display-mode, data will be fed to
the HV-buffer Cell and level-shifted to the required level.
7.10 Level selector
Level Selector is a control of the display synchronization. Display voltage can be separated into
two sets and used with different cycles. Synchronization is important since it selects the
required LCD voltage level to the HV Buffer Cell, which in turn outputs the COM or SEG LCD
waveform.
7.11 HV Buffer Cell (Level Shi f t er)
HV Buffer Cell works as a level shifter, which translated the low voltage output signal to the
required driving voltage. The output is shifted out with an internal FRM clock, which comes
from the Display Timing Generator. The voltage levels are given by the level selector, which is
synchronized with the internal M signal.

7.15 Data Read / Write
To read data from the GDDRAM, input High to R/W(WR#) pin and D/C# pin for 6800-series parallel
mode. Low to E(RD#) pin and High to RS pin for 8080-series parallel mode. No data read is provided
for serial mode. In normal mode, GDDRAM column address pointer will be increased by one
automatically after each data read. Also, a dummy read is required before the first data is read. See
Figure 3 in Functional Description.
To write data to the GDDRAM, input Low to R/W(WR#) pin and High to D/C# pin for 6800-series
parallel mode. For serial interface, it will always be in write mode. GDDRAM column address pointer
will be increased by one automatically after each data write. The address will be reset to 0 in next data
read/write operation is executed when it is 95.
Remarks: Only read d ata on Page 0 to Page 7 of the GDDRAM. The data on Icon page (page 8)
cannot be read.

8.30 OTP setting and programming
OTP (One Time Programming) is a method to adjust Vout. In order to eliminate the variations of
LCD module in term of contrast level, OTP can be used to achieve the best contrast of every
LCD modules.
OTP setting and programming should include two major steps of (1) Find the OTP offset and
(2) OTP programming as following,
Step 1. Find OTP offset
(1) Hardware Reset (sending an active low reset pulse to
(2) Send original initialization routines
(3) Set and display any test patterns
(4) Adjust the contrast value (0x81, 0x00~0x3F) until there is the best visual contrast
(5) OTP setting steps = Contrast value of the best visual contrast - Contrast value of original
initialization
Example 1:
Contrast value of original initialization = 0x20
Contrast value of the best visual contrast = 0x24
OTP setting steps = 0x24 - 0x20 = +4
OTP setting commands should be (0x82, 0x14)
Example 2:
Contrast value of original initialization = 0x20
Contrast value of the best visual contrast = 0x1B
OTP setting steps = 0x1B - 0x20 = -5
OTP setting commands should be (0x82, 0x1B)
RES# pin)

Step 2. OTP programming
(6) Hardware Reset (sending an active low reset pulse to
RES# pin)
(7) Enable Oscillator (0xAB)
(8) Connect an external Vout (see diagram below)
(9) Send OTP setting commands that we find in step 1 (0x82, 0x10~0x1F)
(10) Send OTP programming command (0x83)
(11) Wait at least 2 seconds
(12) Hardware Reset
Verify the result by repeating step 1. (2) – (3)
