1. INTRODUCTION
The ST7556 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segment
and 65 common with 1 ICOM driver circuits. This chip is connected directly to a microprocessor, accepts 4-line serial
interface (SPI) or 8-bit parallel interface, display data can store in an on-chip display data RAM of 66 x 102 bits. It
performs display data RAM read/write operation with no external operating clock to minimize power consumption. In
addition, because it contains power supply circuits to drive liquid crystal, it is possible to make a display system with the
fewest components.

LCD DRIVER SUPPLY
OSC
I
When the on-chip oscillator is used, this input must be connected
to VDD. An external clock signal, if used, is connected to this input. If
the oscillator and external clock are both inhibited by connecting the
OSC pin to VSS the display is not clocked and may be left in a DC state.
To avoid this, the chip should always be put into Power Down Mode
before stopping the clock.

6. FUNCTIONS DESCRIPTION
MICROPROCESSOR INTERFACE
Chip Select Input
There is CSB pin for chip selection. The ST7556 can interface with an MPU when CSB is "L". When CSB is "H", these pins
are set to any other combination, A0, /RD(E), and /WR(R/W) inputs are disabled and D0 to D7 are to be high impedance.
And, in case of serial interface, the internal shift register and the counter are reset.
Parallel / Serial Interface
ST7556 has three types of interface with an MPU, which are one serial and two parallel interfaces. This parallel or serial
interface is determined by P/S pin as shown in table 1.

Parallel Interface (P/S = "H")
The 8-bit bi-directional data bus is used in parallel interface and the type of MPU is selected by IMS as shown in table 2.
The type of data transfer is determined by signals at A0, /RD (E) and /WR(R/W) as shown in t
ab
le 3.

NOTE: When /RD (E) pin is always pulled high for 6800-series interface, it can be used CSB for enable signal. In this case,
interface data is latched at the rising edge of CSB and the type of data transfer is determined by signals at A0, /WR(R/W)
as in case of 6800-series mode.

When the ST7556 is active (CSB="L"), serial data (D6) and serial clock (D7) inputs are enabled. And not active, the internal
8-bit shift register and the 3-bit counter are reset. The display data/command indication may be controlled either via
software or the Register Select (A0) Pin, based on the setting of P/S. When the A0 pin is used (IMS = "H"), data is display
data when A0 is high, and command data when A0 is low. When A0 is not used (IMS = "L"), the LCD Driver will receive
command from MCU by default. If messages on the data pin are data rather than command, MCU should send Data
direction command to control the data direction and then one more command to define the number of data bytes will be
write. After these two continuous commands are sending, the following messages will be data rather than command. Serial
data can be read on the rising edge of serial clock going into D7 and processed as 8-bit parallel data on the eighth serial
clock. And the DDRAM column address pointer will be increased by one automatically. The next bytes after the display
data string are handled as command data.

Busy Flag
The Busy Flag indicates whether the ST7556 is operating or not. When D7 is "H" in read status operation, this device is in
busy status and will accept only read status instruction. If the cycle time is correct, the microprocessor needs not to check
this flag before each instruction, which improves the MPU performance.
Data Transfer
The ST7556 uses bus holder and internal data bus for data transfer with the MPU. When writing data from the MPU to
on-chip RAM, data is automatically transferred from the bus holder to the RAM as shown in figure 3. And when reading
data from on-chip RAM to the MPU, the data for the initial read cycle is stored in the bus holder (dummy read) and the MPU
reads this stored data from bus holder for the next data read cycle as shown in figure 4. This means that a dummy read
cycle must be inserted between each pair of address sets when a sequence of address sets is executed. Therefore, the
data of the specified address cannot be output with the read display data instruction right after the address sets, but can be
output at the second read of data.

DISPLAY DATA RAM (DDRAM)
The ST7556 contains a 65X102 bit static RAM that stores the display data. The display data RAM store the dot data for the
LCD. It has a 65(8 pageX8 +1) X102, and extra ICOM. There is a direct correspondence between X-address and column
output number. It is 65-row by 102-column addressable array. Each pixel can be selected when the page and column
addresses are specified. The 65 rows are divided into 8 pages of 8 lines and 1 page of 1 line. Data is read from or written to
the 8 lines of each page directly through D0 to D7. The display data of D0 to D7 from the microprocessor correspond to the
LCD common lines. The microprocessor can read from and write to RAM through the I/O buffer. Since the LCD controller
operates independently, data can be written into RAM at the same time as data is being displayed without causing the LCD
flicker.
Page Address Circuit
This circuit is for providing a Page Address to Display Data RAM shown in figure 6. It incorporates 4-bit Page
Address register changed by only the "Set Page" instruction. Page Address 9 is a special RAM area for the icons and
display data D0 is only valid.
Column Address Circuit
Column Address Circuit has an 8-bit preset counter that provides Column Address to the Display Data RAM as shown in
figure 5. The display data RAM column address is specified by the Column Address Set command. The specified column
address is incremented (+1) with each display data read/write command. This allows the MPU display data to be accessed
continuously.
ADDRESSING
Data is downloaded in bytes into the RAM matrix of ST7556 as indicated in Figs.5, 6, 7. The display RAM has a matrix of
65 by 102 bits. The address pointer addresses the columns. The address ranges are: X 0 to 101 (1100101), Y 0 to 8 (1000).
Addresses outside these ranges are not allowed.
In vertical addressing mode (V=1) the Y address increments after each byte (see Fig.7). After the last Y address (Y = 8) Y
wraps around to 0 and X increments to address the next column.
In horizontal addressing mode (V=0) the X address increments after each byte (see Fig.6). After the last X address
(X = 101) X wraps around to 0 and Y increments to address the next row.
After the very last address (X = 101, Y = 8) the address pointers wrap around to address (X = 0, Y =0)

Oscillator
The on-chip oscillator provides the clock signal for the display system. No external components are required and the OSC
input must be connected to VDD. An external clock signal, if used, is connected to this input.
Display Timing Generator Circuit
This circuit generates some signals to be used for displaying LCD. The display clock, CL (internal), generated by oscillation
clock, generates the clock for the line counter and the signal for the display data latch. The line address of on-chip RAM is
generated in synchronization with the display clock and the display data latch circuit latches the 102-bit display data in
synchronization with the display clock. The display data, which is read to the LCD driver, is completely independent of the
access to the display data RAM from the microprocessor. The display clock generates an LCD AC signal (M) which
enables the LCD driver to make a AC drive waveform, and also generates an internal common timing signal and start
signal to the common driver. Driving waveform and internal timing signal are shown in Figure 8.

Caution
As the programming range for the internally generated VLCDIN allows values above the max allowed VLCDIN, the
customer has to ensure while setting the VOP register that under all condition and including all tolerances the
VLCD limit of max. 13V will never be exceeded. As VLCDIN increases with lower temperatures, care must be taken
not to set a Vop generating a VLCDIN voltage that will exceed the maximum of 10.6V when operating at 40 .

16. THE MPU INTERFACE (REFERENCE EXAMPLES)
The ST7556 Series can be connected to either 80X86 Series MPUs or to 6800 Series MPUs. Moreover, using the serial
interface it is possible to operate the ST7556 series chips with fewer signal lines.
The display area can be enlarged by using multiple ST7556 Series chips. When this is done, the chip select signal can be
used to select the individual ICs to access.
