Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with the PSoC Designer development environment. Confirm that the selected variant meets the required I/O count and peripheral configuration for the target design.

Selection Notes

Select this component when a design requires a single-chip solution combining analog signal processing with USB connectivity. The PSoC architecture allows hardware customization via drag-and-drop user modules, reducing external component count. Consider the available GPIO count and memory size relative to application complexity before finalizing the part number.

Part Context

This device belongs to the CY8C24x94 series of PSoC Programmable System-on-Chips. These devices are designed to replace multiple traditional MCU-based components by integrating configurable analog and digital logic on a single die. The series targets applications needing flexible peripheral configurations and low power consumption.

Replacement Considerations

Check the CY8C24794, CY8C24894, and CY8C24994 variants within the same datasheet for pin-compatible or functionally similar alternatives. Verify differences in GPIO counts, memory sizes, and specific peripheral availability before substitution.
