Description

The T6C84 is a driver for a small-to-medium-sized 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 a serial interface circuit. It generates all the timing signals for the display using an on-chip oscillator. T6C84 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 T6C84 has 136 column driver outputs and 34 row driver outputs enabling it to drive a 136-dot by 34-dot LCD. In addition, there are resistors to divide the bias voltage, a power supply op-amp, DC-DC converter (doubler, tripler, quadruplexer) and contrast control circuit enabling the LCD to be driven by a single power supply.
