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

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.
