Cxlc8967 is a special LCD driver control circuit with keyboard scanning interface, which is internally integrated with MCU digital interface, data latch, LCD driver, keyboard scanning, magic color backlight driver and other circuits. This product has excellent performance and reliable quality. It does not need to change the bottom instruction of the decoding board. It is fully compatible with the instruction set of the existing 3 communication port LED Driver IC of tianmicroelectronics. The existing decoding board supporting LED display can be directly connected to the front panel of LCD display, without the need to add a single chip computer to scan the keys (or scan the keys through the decoding board), without the need to use ht6221 to scan the keys.
