• Supports direct LCD driving capabilities
• Includes CapSense technology for touch sensing

Applications

• Portable consumer electronics
• Industrial control systems
• Smart home devices

Procurement Notes

Verify the specific suffix 'X' against official Infineon documentation to confirm if it denotes a specific tape-and-reel packaging variant or environmental compliance status. Confirm the exact pinout and voltage range requirements for your PCB design before ordering.

Selection Notes

Select this component when an 8-bit MCU with integrated analog peripherals and low power consumption is required. Ensure the 24-pin form factor fits the mechanical constraints and that the 16 Kb memory size meets application needs.

Part Context

This part belongs to the PSoC 21x45/22x45 family, which combines a standard 8-bit CPU with configurable analog and digital blocks. This architecture allows for high integration in space-constrained designs by reducing external component count.

Replacement Considerations

Check for CY8C22545 variants within the same family. Verify pin compatibility and memory size differences before substituting.
