W82C610
MONITOR SOFTWARE OSD IC
GENERAL DESCRIPTION
The W82C610 and SoftControl software provide a proprietary Software On-Screen-Display (OSD)
solution for monitors. It delivers excellent performance and flexibility over hardware OSD solution in
current monitor industry. User can adjust monitor from SoftControl under Window (R) environment
instead of adjustment from front panel. The W82C610 decodes the RGB video signals generated by a
SoftControl program from the host, over normal VGA cable, and produces control data that can be
accessed by the display microcontroller.
FEATURES
• A delicate solution for software On-Screen-Display
• Excellent performance and flexibility over Hardware OSD
• Low cost implementation for existing monitors
• 16-pin PDIP
• 5V CMOS device
• ESD protection (> 4 KV)
SoftControl Feature List
• Five languages selectable for icon label
• Fully adjustable
− Brightness, Contrast, Parallelogram, Pincusion
− Position, Size, Symmetry, Trapezoid, Color
− Factory Preset
• Current system status
− Input connect type
− H/V frequency, Interlace/Non-interlace
− Operating resolution
− Degauss

FUNCTIONAL DESCRIPTION
The W82C610 converts analog video signals to digital data and detects the SoftControl signature
code. If the signature code is detected, the W82C610 informs the microcontroller and places the
SoftControl data on the parallel bus.
SoftControl allows the PC to communicate with the monitor over the normal video cable. No
additional circuits are required in the PC. Communication is accomplished by means of coded data
transferred on the RGB video signals by the SoftControl program. To prevent false readings, data are
sent with a 12-bit signature code.
The W82C610 provides a data path for inputs from key pad to microcontroller. Output ODB0-ODB3
can be either from key pad (IDB0−IDB3) or from VGA cable (RDATA, GDATA, BDATA).
