Procurement Notes

Verify the specific suffix M485T against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB assembly requirements by checking the footprint details in the datasheet. Confirm that the component meets all necessary regulatory standards for your target market before finalizing procurement decisions.

Selection Notes

Select this model when a balance of processing speed and extensive peripheral count is required. The inclusion of CAPSENSE reduces external component needs for touch applications. Consider the 48 MHz clock speed for real-time processing tasks while evaluating the available GPIO count against your interface requirements.

Part Context

This component belongs to the PSoC 4 series, which combines a low-power ARM Cortex-M0 processor with highly configurable analog and digital peripherals. The series is designed for applications requiring flexibility in mixed-signal environments, allowing designers to customize hardware resources to fit specific application needs without changing the core silicon.

Replacement Considerations

Consult Infineon's cross-reference tools for verified pin-compatible or functionally equivalent alternatives within the PSoC 4 family. Ensure any substitute part maintains the same package dimensions and electrical characteristics to avoid redesigning the host circuit board.
