Column and Row Driver LSI for a Dot Matrix Graphic LCD
T6A04A
The T6A04A is a driver for a small-to-medium-sized scale dot
matrix graphic LCD. It includes the functions of the T9841B
(column driver) and the T9842B (row driver). It has an 8-bit
interface circuit and can be operated with an 80-Series MPU. It
generates all the timing signals for the display with an on-chip
oscillator. It receives 8-bit data from an MPU, latches the data to
an on-chip RAM, and displays the image on the LCD (the data in
the display RAM correspond to the dots on the display). The
device has 120 column driver outputs and 64 row driver outputs
enabling it to drive a 120-dot by 64-dot LCD. In addition, there
are resistors to divide the bias voltage, a power supply op-amp,
DC-DC converter (+5 V →−5 V) and contrast control circuit,
enabling the LCD to be driven by a single power supply. The
device can be connected to another T6A04A to drive a 240-dot by
64-dot LCD.
