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.

LCD driver supply voltages

 

 

 

 

 

 

The voltage determined by LCD pixel is impedance-converted by an operational amplifier

 

 

for application.

 

 

 

 

 

 

 

 

Voltages should have the following relationship;

 

 

 

 

V0 ³ V1 ³ V2 ³ V3 ³ V4 ³ VSS

 

 

V0

 

When the internal power circuit is active, these voltages are generated as following table

V1

 

according to the state of LCD Bias.

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")

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.

65 COM / 132 SEG DRIVER & CONTROLLER FOR STN LCD

S6B1713

 

 

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 4. 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 5. 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.
