T6B66BFG
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
T6B66BFG
ROW DRIVER LSI FOR DOT MATRIX LCD
The T6B66BFG is a row (common) driver LSI for a small- or
medium-scale dot matrix LCD.
The T6B66BFG generates timing signals for the display using
an on-chip oscillator and also controls the T6B65AFG column
(segment) LCD driver.
www.DataSheet4U.com Four duty options are available: 1/17, 1/33, 1/49 and 1/65.
The IC is equipped with 65 low-impedance row-driver outputs.
Moreover, the IC incorporates internal resistors to divide the bias
voltage, a power supply operational amplifier, DC-DC converter
and a contrast control circuit; it is therefore easy to construct a
low-power LCD system consisting of a T6B66BFG and a
T6B65AFG column (segment) LCD driver.
T6B66BFG is lead (Pb)-free product.

Note: The resistance values are typical values.
The oscillation frequency depends on how the
device is mounted. It is necessary to adjust the
oscillation frequency to a target value.
● Timing generation circuit
This circuit divides the signals from the oscillator and generates display timing signals (CL, PM) and the
operating clock ( / φ) signal.
● Shift register
65-bit shift register
● DC-DC converter (tripler and quadrupler)
The T6B66BFG has an on-chip DC-DC tripler and quadrupler. When / STB = L, VOUT1 and VOUT2 = VDD.
A 2.2 to 10-µF capacitor is recommended for this DC-DC Converter.

Tripler mode
When not using the DC-DC converter, leave the CnA, CnB and VOUTn pins open and connect an external
VEE supply.
