Procurement Notes

Verify the specific suffix M485T against official Infineon documentation to confirm tape-and-reel packaging and temperature grade. Ensure compatibility with required voltage ranges and interface configurations before integration. Cross-reference the component marking code with datasheet specifications to validate authenticity and revision level during procurement processes.

Selection Notes

Select this model when a balance of processing speed and analog flexibility is required. The 48 MHz clock speed suits moderate computational loads. Verify that the available GPIO count meets system pin requirements. Consider the integrated CAPSENSE™ feature if touch interaction is necessary without external controllers. Check power supply constraints against the specified operating voltage range.
