Description
Electronic Component Model: NT6861-0023 is a monitor component microcontroller (mC) designed for auto-sync and digital controlled applications. It features a 6502 8-bit CPU core, 256 bytes of RAM for working and stack area, 24K bytes of ROM for programming, 14-channel 8-bit PWM D/A converters, 2-channel A/D converters for key detection, an 8-bit pre-loadable base timer, internal Hsync and Vsync signals processor for mode detection, a watch-dog timer for preventing abnormal operation, and an I2C bus interface. Users can store EDID data in the 128 bytes of RAM for DDC1/2B, eliminating the need for a dedicated EEPROM and saving on component costs.
