T6A04A

T6A04A TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic T6A04A Column and Row Driver LSI for a Dot Matrix Graphic LCD 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 www.DataSheet4U.com 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.
