T6K11
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
T6K11
DOT MATRIX LCD DRIVER
The T6K11 driver is designed for use in small to medium−sized
dot matrix LCD panels. This driver can be interfaced to the MPU
via a 4 / 8−bit (68 / 80−series) or a serial interface, and is
operated asynchronously with the MPU. Since the T6K11
contains an CR circuit clock driver, it can generate the timing
signals required for the LCD.
The display data can be stored in the built−in display RAM,
whose cells each correspond to each dot on the dot−matrix LCD.
The display data written to the RAM corresponds one for one to
the LCD drive signals output by the device. Since the T6K11 has
160 outputs for the LCD drive (segment) signals that constitute
display data and 65 outputs for the LCD drive (common) signals
that constitute scanning signals, this single device allows you to
drive an LCD panel comprised of up to 160 × 65 dots with a
minimum of power requirement.
To minimize its power consumption, the T6K11 has a display
change mode (power save mode) in which only a 160 × 1−dot icon can be displayed. What’s more, it has various
built−in analog circuits such as a D / A converter for the LCD drive power supply, a step−up circuit (×2 to ×5), and
a contrast control (electronic VR) circuit. All these circuits enable the LCD panel to be driven with a single power
supply.
This product is under development; hence, specifications may change without notice. When you use this product,
please refer to the latest technical datasheet.

TOSHIBA is continually working to improve the quality and reliability of its products. Nevertheless, semiconductor devices in general
can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the
buyer, when utilizing TOSHIBA products, to comply with the standards of safety in making a safe design for the entire system, and
to avoid situations in which a malfunction or failure of such TOSHIBA products could cause loss of human life, bodily injury or
damage to property.
In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the
most recent TOSHIBA products specifications. Also, please keep in mind the precautions and conditions set forth in the “Handling
Guide for Semiconductor Devices,” or “TOSHIBA Semiconductor Reliability Handbook” etc..
·
The TOSHIBA products listed in this document are intended for usage in general electronics applications (computer, personal
equipment, office equipment, measuring equipment, industrial robotics, domestic appliances, etc.). These TOSHIBA products are
neither intended nor warranted for usage in equipment that requires extraordinarily high quality and/or reliability or a malfunction or
failure of which may cause loss of human life or bodily injury (“Unintended Usage”). Unintended Usage include atomic energy
control instruments, airplane or spaceship instruments, transportation instruments, traffic signal instruments, combustion control
instruments, medical instruments, all types of safety devices, etc.. Unintended Usage of TOSHIBA products listed in this document
shall be made at the customer’s own risk.

Polyimide base film is hard and thin. Be careful not to injure yourself on the film or to scratch any other parts with the film. Try to
design and manufacture products so that there is no chance of users touching the film after assembly, or if they do , that there is no
chance of them injuring themselves. When cutting out the film, try to ensure that the film shavings do not cause accidents. After use,
treat the leftover film and reel spacers as industrial waste.
·
Light striking a semiconductor device generates electromotive force due to photoelectric effects. In some cases this can cause the
device to malfunction.
This is especially true for devices in which the surface (back), or side of the chip is exposed. When designing circuits, make sure
that devices are protected against incident light from external sources. Exposure to light both during regular operation and during
inspection must be taken into account.
