NT68P62-01 General Description
The NT68P62 is a new generation of monitor mC for autosync 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-channel of 8-bit PWM D/A converters, 4-channel A/D converters for keys detection which can save I/O pins, one 8-bit pre-loadable base timer, internal Hsync and Vsync signals processor, and a watch-dog timer which prevents the system from abnormal operation and two I2C bus interface. 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.
And Half frequency output function can save external oneshot circuit. All of these designs are committed to offer our user saving component cost. The 42 pin S-DIP IC provides two additional I/O pins port40 & port41, Part number NT68P62U represents the S-DIP IC. For future reference, port40 & port42 is only available for the 42 pin S-DIP IC.
