STV7733 320 output dot-matrix display driver

The STV7733 device is a low-power, controller/driver IC for dot-matrix displays. Data is encoded on two bits to select one of four possible output states: high level, medium level, ground or high impedance (Hi-Z).

Inputs AOC1 and AOC2 control the all output stages simultaneously to select one of five possible configurations: high level, medium level, ground, Hi-Z or data through.

Except for the data through mode, the configuration selected by AOC1 and AOC2 is applied to all outputs at the same time.

The STV7733 communicates with the host controller through an 8-bit parallel interface. The input data bus is organized as four, 2 x 80-bit shift registers operating in parallel at a maximum clock frequency of 10MHz.

Logic inputs are LVCMOS compatible.

The STV7733 is available in bumped die form. Bumped die can be assembled in either a TCP or COG module
