Product Summary
The NT68F63LG is a new generation of monitor μC for autosync and digital control applications. Particularly, the NT68F63LG supports various functions to allow users to easily develop USB monitors. The NT68F63LG contains the 6502 8-bit CPU core, 512 bytes of RAM for use as working RAM and as stack area, 32K bytes of Flash memory, 13-channels of 8-bit PWM D/A converters, 4-channel A/D converters for detection of keys which can save I/O pins, one 8-bit pre-loadable base timer, an internal Hsync and Vsync signals processor and a watch-dog timer, which prevents the system from abnormal operation and two IIC bus interfaces.
