It connects microprocessor with 8-digit 7-segment digital LED display, bar graph display or 64 independent LEDs. It includes an on-chip B-type BCD encoder, multi-channel scanning circuit, segment driver, and an 8 * 8 static RAM to store every data. Only one external register is used to set the segment current of each LED.\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv\u003e\n    \n\u003c\/div\u003e \n\u003cdiv\u003e \n \u003cspan style=\"font-size:16px\"\u003eA convenient four wire serial interface can connect all general purpose microprocessors.
