General Description
NT68P61A is a monitor component
碌C
for auto-sync and
digital controlled applications. It contains a 6502
and stack area, 24K bytes of OTP ROM**, 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
2
system from abnormal operation, and an I C bus
interface. The LVRC enables NT68P61A operate
properly.
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.
** The NT6861 (MASK ROM type) will provide
4/8/12/16/24K bytes program ROM.
