Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm the operating temperature range and voltage specifications match your design requirements. Ensure compatibility with the PSoC Designer development environment for programming and configuration. Check for any end-of-life notices or alternative part recommendations from the manufacturer.

Selection Notes

Select this model if your application requires a mix of analog and digital peripherals on a single chip. The CY8C24423A offers sufficient memory for moderate firmware complexity. Consider the 28-pin SSOP package constraints for board layout. Evaluate the need for high-resolution ADCs or PWM outputs available through the configurable PSoC blocks.

Part Context

This component belongs to the CY8C24x23A series of PSoC 1 devices. It shares architectural similarities with other members like the CY8C24123A and CY8C24223A, differing primarily in memory size and I/O count. The series is designed for cost-sensitive applications requiring high integration levels.

Replacement Considerations

Check for direct substitutes within the CY8C24x23A family such as CY8C24123A or CY8C24223A, ensuring pinout and memory compatibility. Verify if newer generations like PSoC 4 or PSoC 5LP offer suitable upgrades with similar functionality but improved performance.
