Procurement Notes
Verify the suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm current availability status as distribution channels may report limited stock or end-of-life conditions. Ensure RoHS compliance documentation matches specific manufacturing dates. Cross-reference pinout compatibility with existing PCB layouts before procurement.
Selection Notes
Select this model for designs requiring high integration of analog and digital functions in a compact footprint. The 48 MHz processing speed suits moderate complexity control tasks. Verify that the 38 available I/O pins meet interface requirements. Consider the operating temperature range and voltage specifications against environmental constraints.
Part Context
This part belongs to the Infineon PSoC 4 family, which combines a CPU with configurable analog and digital peripherals. The CY8C4246 variant specifically targets general-purpose applications needing efficient power management and flexible connectivity options within the TQFP-48 form factor.
Replacement Considerations
Check for CY8C4246AZA-M443 for similar specifications in different packaging. Evaluate CY8C4246AZI-M443 for alternative temperature grades or package types within the same series.
