W82C610

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.

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). -3- Publication Release Date: October 1995 Revision A4 W82C610 ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage (VCC to VSS) Analog Input Voltage Digital Input Voltage Power Dissipation Ambient Operating Temperature Lead Temperature (Soldering, 10 sec) RATING 5.5 VSS-0.5 to VCC+0.5 VSS-0.5 to VCC+0.5 5 0 to 70 250 UNIT V V V mW °C °C Note: Exposure to conditions beyond those listed under Absolute Maximum Ratings may adversely affect the life and reliability of the device.
