CRT9021B-026P

Application Specific Microcontrollers Overview

The CRT9021B-026P is a display controller manufactured by SMSC, designed for driving displays using MOS technology. The device is housed in a CDIP40 package with a dual inline form factor and ceramic body material. It operates on a nominal 5 V power supply and supports through-hole terminals with a 2.54 mm pitch. The component is rated for commercial temperature ranges, functioning between -40 °C and +70 °C. It features 40 terminals and is not surface mountable. The unit weight is approximately 2 kg.

Application Specific Microcontrollers Feature Summary

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix '-026P' against official SMSC documentation to confirm pinout and electrical characteristics, as generic listings may lack detailed revision data. Ensure compliance with RoHS requirements if applicable, as some sources indicate non-compliance status for similar variants. Confirm availability through authorized channels given potential discontinuation or limited stock.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated display controller with MOS interface is required in a through-hole ceramic package. Ensure the design accommodates the 5 V supply requirement and the physical dimensions of the CDIP40 housing. Verify thermal management capabilities for the specified commercial temperature range during operation.

Application Specific Microcontrollers Part Context

The CRT9021B series belongs to SMSC's lineup of display controllers. The CRT9028CD is a related variant within the same family, sharing similar MOS technology and DIP40 packaging but potentially differing in specific interface configurations or pin assignments. Both serve as core components for display driving applications in embedded systems.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes are not explicitly listed in public databases. Evaluate other SMSC display controllers or compatible MOS-based display drivers with matching CDIP40 footprints and 5 V operation. Verify pin compatibility before replacement.
