Preliminary TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
T6K41
Column and Row Driver LSI for a Dot Matrix Graphic LCD
T6K41
The T6K41 is a driver for a small-to-medium-sized dot matrix
graphic LCD, especially for four-gray-scale monochromatic STN
LCDs. This driver can be interfaced to the MPU via an 8-bit
Unit: mm
(80/68-series) or a serial interface, and is operated
asynchronously with the MPU.
Since the T6K41 contains a CR oscillator, it can generate the

The T6K41 has 128 outputs for the LCD drive (segment)

drive (common) signals that constitute the scanning signals and

T6K41 has 128 × 128 × 2 bits display RAM and 16-bit register.
Thus, this single device allows you to drive an LCD panel
TCP (Tape Carrier Package)
comprised of up to 128 × 128 + 16 dots with a minimize of power
requirement. It also incorporates a gray-scale function.
The display RAM of the T6K41 is a two-port RAM so that the
MPU access it without any wait time.
To minimize power consumption, the T6K41 has a display change mode (power save mode) in which only a 16-dot
icon can be displayed. Furthermore, it has various built-in analog circuits such as a voltage regulator, voltage
divider resistors, power supply op-amp, DC-DC converters (×2 to ×6) and a contrast control (electronic volume)
circuit. All these circuits enable the LCD panel to be driven with a single power supply.
