Procurement Notes

Verify the specific ordering suffix L475 corresponds to the TQFP-64 package variant when sourcing. Confirm that the required flash capacity of 128 kB and I/O count meet the system requirements. Ensure compatibility with the PSoC Creator IDE for firmware development. Check for any specific environmental certifications required for the target deployment region.

Selection Notes

Select this component if the design requires a combination of ARM Cortex-M0 processing with extensive programmable analog resources. It is suitable for applications needing multiple communication interfaces like USB and CAN alongside precise analog signal acquisition. Consider the 48 MHz clock speed for real-time processing needs. Evaluate the pin count against the available GPIO and peripheral routing requirements.

Part Context

This part belongs to the Infineon PSoC 4200L family, which is designed for scalable embedded control. The L-Series variant typically offers optimized low-power characteristics compared to standard series.
