64COM/128SEG GRAPHIC DRIVER FOR DOT MATRIX LCD
S6B0708
INTRODUCTION
S6B0708 is a single-chip LCD driver IC for liquid crystal dot-matrix graphic display systems. It incorporates 192
driver circuit for 64 common and 128 segment and 64 x 128-bit bit-map RAM. It is capable of interfacing with the
microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an one chip display data
RAM. And it generates internal signals for using LCD driving independent of microprocessor clock.
FEATURES
• 64-channel common & 128-channel segment driver for dot matrix LCD
• On-chip display data RAM: 64 × 128 = 8192bits
• Display data is stored in display data RAM from MPU
- RAM bit data: ON(1), OFF(0)
• Internal timing generator circuit for dynamic display
• 8-bit parallel bi-directional data bus
• Applicable LCD duty: 1/64
• Power supply voltages: Power supply voltage range: 4.5 - 5.5V (VDD)
• LCD driving voltage range: 8.0 - 17.0V (VLCD = VDD-VEE)
• Wide operating temperature range: Ta = -30°C - 85°C
• High voltage CMOS process
• Gold bumped chip available

BUSY FLAG
Busy flag indicates whether S6B0708 is operating or not. When it is high, S6B0708 is in internal operation. When
it is low, S6B0708 can accept the data or instruction. DB7 indicates busy flag of the S6B0708.

DISPLAY TIMING GENERATOR CIRCUIT
This section explains how the timing generation circuit operates.
• Signal generation to display start line counter and display data latch circuit.
• The display clock (CLK2) generates a clock to the line counter. The display start line address
of the display RAM is synchronized with the display clock. 128-bit display data is latched by
the display data latch circuit in synchronization with the display clock and output to the
segment LCD drive output pin.
• LCD AC signal (M) generation.
