General Description
The NT6862 is a new generation monitor
μ
C 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 I
2
C 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 S-
DIP IC. For future reference, port40 & port42 are only
available for the 42 pin S-DIP IC.
