5V CMOS technology for low power consumption 6502 8-bit CMOS CPU core 8 MHz operation frequency 32K bytes of flash memory for Multi -Times Program 512 bytes of RAM 2Kbytes Masked BootROM for ISP.
One 8-bit base timer 13 channels of 8-bit PWM outputs with 5V open drain 4 channel A/D converters with 6-bit resolution 25 bi-directional I/O port pins (8 dedicated I/O pins) Hsync/Vsync signals processor for separate & composite signals, including hardware sync signals polarity detection and freq.
counters with 2 sets of Hsync counting intervals Hsync/Vsync polarity controlled output, 5 selectable free run output signals and self-test patterns, automute function, half freq.
I/O function Two built-in IIC bus interfaces support VESA DDC1/2B+ General Description The NT68F62 is a new generation of monitor µC for autosync and digital control applications.
Particularly, this chip supports various functions to allow users to easily develop USB monitors.
It 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 w w .
