CRT8002C-0003P

Overview

The CRT8002C-0003P is a CRT video attributes controller manufactured by SMSC. It is a MOS memory circuit housed in a 28-pin PDIP package with a dual inline terminal configuration and 2.54 mm pitch. The device operates at 5V, supports through-hole mounting, and functions within a commercial temperature range of -40°C to 70°C.

Feature Summary

• Provides four distinct cursor display modes including underline, blinking underline, reverse video block, and blinking reverse video block.

Applications

• CRT video attribute control systems
• Legacy computer display interfaces

Procurement Notes

Verify the manufacturer designation as SMSC or Microchip, noting corporate acquisitions. Confirm the specific suffix 'C-0003P' matches the required pinout and electrical characteristics. Ensure the DIP-28 package type aligns with existing board layouts. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this component specifically for legacy CRT monitor designs requiring dedicated hardware-based cursor generation. It serves as a parity generator and checker for video data streams. Consider availability constraints due to its status as an older industrial component compared to modern FPGA alternatives.

Part Context

This part belongs to the CRT8002 family of video controllers designed for monochrome and color CRT displays. It handles video timing and attribute generation tasks essential for maintaining stable image presentation on cathode ray tube monitors used in early computing environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with CRT8002A-003P or CRT8002B variants may be necessary, but functional equivalence must be verified against official datasheets before substitution.
