NT6862

The NT6862 is a new generation monitor mC for auto-sync and digital control applications. Particularly, this chip supports various and efficient functions to allow users to easily develop USB monitors. It contains the 6502 8-bit CPU core, 512 bytes of RAM used as working RAM and stack area, 32K bytes of OTP ROM, 13-channels of 8-bit PWM D/A converters, 4-channel A/D converters for key detection which save I/O pins, one 8-bit pre-loadable base timer, internal Hsync and Vsync signals processor, a Watch-dog timer which prevents the system from abnormal operation, and two I2C bus interfaces. The user can store EDID data in the 128 bytes of RAM for DDC1/2B, so that user can reduce a dedicated EEPROM for EDID. A Half frequency output function can save external one-shot circuit. These designs are committed to reduce component cost. The 42 pin S-DIP IC provides two additional I/O pins port40 & port41, Part number NT6862U represents the SDIP IC. For future reference, port40 & port42 are only available for the 42 pin S-DIP IC.
