Precautions for Light
Light has characteristics to move electrons in the integrated circuitry of semiconductors,
therefore may change the characteristics of semiconductor devices when irradiated with light.
Consequently, the users of the packages which may expose chips to external light such as
COB, COG, TCP and COF must consider effective methods to block out light from reaching
the IC on all parts of the surface area, the top, bottom and the sides of the chip. Follow the
precautions below when using the products.
1.
Consider and verify the protection of penetrating light to the IC at substrate (board or
glass) or product design stage.
2.
Always test and inspect products under the environment with no penetration of light.

65 COM / 132 SEG DRIVER & CONTROLLER FOR STN LCD
INTRODUCTION
The S6B1713 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 65
commons and 132 segments driver circuits. This chip is connected directly to a microprocessor, accepts serial or
8-bit parallel display data and stores in an on-chip Display Data RAM of 65 x 132 bits. It provides a high-flexible
display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it
performs display data RAM read/write operation with no externally operating clock to minimize power consumption.
In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display
system with the fewest components.

FUNCTIONAL DESCRIPTION
MICROPROCESSOR INTERFACE
Chip Select Input
There are CS1B and CS2 pins for Chip Selection. The S6B1713 can interface with an MPU only when CS1B is “L”
and CS2 is “H”. When these pins are set to any other combination, RS, E_RD, and RW_WR inputs are disabled and
DB0 to DB7 are to be high impedance. And, in case of serial interface, the internal shift register and the counter are
reset.
Parallel / Serial Interface
S6B1713 has three types of interface with an MPU, which are one serial and two parallel interfaces. This parallel or
serial interface is determined by PS pin as shown in table 8.

Serial Interface (PS = "L", MI=”H” or “L”)
When the S6B1713 is active, serial data (DB7) and serial clock (DB6) inputs are enabled. And not active, the internal
8-bit shift register and the 3-bit counter are reset. Serial data can be read on the rising edge of serial clock going into
DB6 and processed as 8-bit parallel data on the eighth serial clock. Serial data input is display data when RS is high
and control data when RS is low. Since the clock signal (DB6) is easy to be affected by the external noise caused by
the line length, the operation check on the actual machine is recommended.

Busy Flag
The Busy Flag indicates whether the S6B1713 is operating or not. When DB7 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 S6B1713 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 8. 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 9.
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 Display Data RAM stores pixel data for the LCD. It is 65-row by 132-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
the 9th page with a single line (DB0 only). Data is read from or written to the 8 lines of each page directly through
DB0 to DB7. The display data of DB0 to DB7 from the microprocessor correspond to the LCD common lines as
shown in Figure 10. 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.

Figure 10. RAM-to-LCD Data Transfer
Page Address Circuit
This circuit is for providing a Page Address to Display Data RAM shown in Figure 12. It incorporates 4-bit Page
Address register changed by only the “Set Page” instruction. Page Address 8 (DB3 is “H”, but DB2, DB1 and DB0
are “L”) is a special RAM area for the icons and display data DB0 is only valid. When Page Address is above 8, it is
impossible to access to on-chip RAM.
Line Address Circuit
This circuit assigns DDRAM a Line A ddress corresponding to the first line (COM1) of the display. Therefore, by
setting line address repeatedly, it is possible to realize the screen scrolling and page switching without changing the
contents of on-chip RAM as shown in figure 12. It incorporates 6-bit line address register changed by only the initial
display line instruction and 6-bit counter circuit. At the beginning of each LCD frame, the contents of register are
copied to the line counter which is increased by CL signal and generates the Line Address for transferring the
132-bit RAM data to the display data latch circuit. However, display data of icons are not scrolled because the MPU
can not access Line Address of icons.

Column Address Circuit
Column address circuit has a 8-bit preset counter that provides column address to the Display Data RAM as shown
in figure 12. When set Column Address MSB / LSB instruction is issued, 8-bit [Y7:Y0] is updated. And, since this
address is increased by 1 each a Read or Write Data instruction, microprocessor can access the display data
continuously. However, the counter is not increas ed and locked if a non-existing address above 84H. It is unlocked
if a column address is set again by set Column Address MSB / LSB instruction. And the Column Address counter is
independent of page address register.
ADC select instruction makes it possible to invert the relationship between the Column Address and the segment
outputs. It is necessary to rewrite the display data on built-in RAM after issuing ADC select instruction. Refer to the
following figure 11.

Display Timing Generator Circuit
This circuit generates some signals to be used for displaying LCD. The display clock, CL, 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 (CL) and the 132-bit display data is latched by the
display data latch circuit 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 2-frame AC driver waveform and
internal timing signal are shown in figure 14.
In a multiple-chip configuration, the slave chip requires the M, CL and DISP signals from the master. Table 11 shows
the M, CL, and DISP status.

Voltage Regulator Circuits
The function of the internal Voltage Regulator circuits is to determine liquid crystal operating voltage, V0, by
adjusting resistors, Ra and Rb, within the range of |V0| < |VOUT|. Because VOUT is the operating voltage of
operational-amplifier circuits shown in figure 20, it is necessary to be applied internally or externally.
For the Eq. 1, we determine V0 by Ra, Rb and V EV . The Ra and Rb are connected internally or externally by INTRS
pin. And VEV called the voltage of electronic volume is determined by Eq. 2, where the parameter α is the value
selected by instruction, "Set Reference Voltage Register", within the range 0 to 63. VREF voltage at Ta = 25°C is
shown in table 14-1.

V0 = ( 1 +  ) x VEV [V] ------ (Eq. 1)

1. LCD driver voltage, V0 = 10V
2. 6-bit reference voltage register = (1, 0, 0, 0, 0, 0)

While RESETB is “L” or Reset instruction is executed, no instruction except read status can be accepted. Reset
status appears at DB4. After DB4 becomes ”L”, any instruction can be accepted. RESETB must be connected to the
reset pin of the MPU, and initialize the MPU and this LSI at the same time. The initialization by RESETB is essential
before used.
