Procurement Notes

Verify the specific ordering suffix L485 against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with the PSoC Creator IDE or supported third-party ARM development tools. Confirm RoHS compliance status as per the latest product documentation before finalizing procurement specifications.

Selection Notes

Select this component when design requirements include 256 kB of non-volatile memory and extensive analog programmability. It is suitable for applications needing dual CAN controllers and USB connectivity within a compact QFN-68 footprint. Consider the 48 MHz processing speed and 32-channel DMA engine for data-intensive tasks requiring efficient peripheral management.

Part Context

This part belongs to the PSoC™ 4200L family, which combines an Arm Cortex-M0 processor with reconfigurable analog and digital subsystems. The L-Series variant emphasizes low-power operation and extended temperature ranges compared to standard M-Series parts, making it ideal for cost-sensitive embedded control applications.

Replacement Considerations

Check the official PSoC 4200L selector guide for direct pin-compatible substitutes within the same package. Verify if higher-memory variants like the CY8C4248 series meet code size requirements without altering board layout.
