The BCT72323 is an LED Display and Keyboard Controller with 8-steps digital dimming control. Ten segment output lines, seven grid output lines, one display memory (14 bytes), control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for use together with the main microcontroller. Control and data are easily communicated to BCT72323 via a fourwire serial interface (DIN, STB, CLK and DOUT).
