General Description
NT6861 is a monitor component
μ
C for auto-sync and
digital controlled applications. It contains a 6502
8-bit CPU core, 256 bytes of RAM used as working RAM
and stack area, 24K bytes of ROM maximum for
programming, 14-channel 8-bit PWM D/A converters, 2-
channel A/D converters for key detection saving I/O pins,
one 8 bit pre-loadable base timer, internal Hsync and
Vsync signals processor providing mode detection,
watch-dog timer preventing system from abnormal
operation, and an I
2
C bus interface.
Users can store EDID data in the 128 bytes of RAM for
DDC1/2B, so that users can save the cost of dedicated
EEPROM for EDID. Half frequency output function can
save external one-shot circuit. All of these designs create
savings in component costs.
* The frequency deviation of ceramic resonator has
+/- 6% maximum.
