T6K14
COLUMN AND ROW DRIVER LSI FOR A DOT MATRIX GRAPHIC LCD
The T6K14 is a driver for a small-to-medium-sized dot matrix
graphic LCD, especially for reflective color STN LCD. It realizes a
4-color or 4-gray-scale display. This driver can be interfaced to

the MPU via an 8-bit (68/80-series) or a serial interface, and is
operated asynchronously with the MPU. Since the T6K14
contains a CR oscillator, it can generate the timing signals
required for the LCD. Since the T6K14 has 128 outputs for the

scanning signals and 65 × 128 × 2 bits display RAM, this single
device allows you to drive an LCD panel comprised of up to 128 ×
64 dots and 128 icons with a minimize of power requirement. It
TCP (Tape Carrier Package)
has 4 gray-scale function. The display RAM of this driver is a 2
port RAM so that the MPU accesses without any wait time. It has
various power circuits such as a voltage regulators, voltage
divider resistors, a power supply op-amp, a contrast control circuit, a temperature compensation circuit, and
DC-DC converter ( ×2, ×3, ×4, ×5 ). All these circuits enable the LCD panel to be driven with a single power supply.
