Overview
The CRT8002B-033 is a CRT video attributes controller manufactured by SMSC. It functions as a parity generator and checker within the logic integrated circuit category. The component is designed to manage specific video signal parameters for cathode ray tube displays, ensuring data integrity through parity checking mechanisms during video attribute processing operations.
Feature Summary
- Integrated parity generation and checking capabilities for video data streams
- Specialized control functionality for CRT video attribute management
Applications
- CRT video display systems requiring attribute control
- Legacy computer graphics interfaces utilizing parity verification
- Video signal processing circuits in older monitor architectures
Procurement Notes
Verify the exact manufacturer designation, as SMSC assets were acquired by Microchip Technology. Confirm package type and suffix variations against official Microchip documentation to ensure compatibility with existing board layouts. Request current datasheets directly from authorized distributors or the manufacturer to validate technical specifications before procurement.
Selection Notes
Select this component specifically for legacy CRT video applications requiring dedicated attribute control and parity checking. Ensure the system architecture supports the specific interface requirements of this IC. Verify that the operating voltage and signal levels match the design constraints of the target video controller circuit.
Part Context
This part belongs to the CRT8002 series of video controllers produced by Standard Microsystems Corporation (SMSC). These components were widely used in early personal computer graphics subsystems. The series provides essential hardware support for generating and verifying parity bits in video memory access paths, a critical feature for maintaining data accuracy in vintage display technologies.
Replacement Considerations
Direct substitutes are not explicitly listed in available public records. Consider reviewing other parts within the CRT8002 family or consulting Microchip's obsolescence notices for recommended alternatives compatible with legacy CRT video controller designs.
