Procurement Notes
Verify that the specific suffix PVXE corresponds to the required 48-pin SSOP package and temperature grade. Confirm that the manufacturer designation aligns with current Infineon ownership following the acquisition of Cypress Semiconductor. Ensure compatibility with existing board layouts regarding pinout and voltage levels before procurement.
Selection Notes
Select this component when an 8-bit MCU with integrated programmable analog resources is necessary. It is suitable for designs requiring flexible peripheral configuration without external components. Consider the 48-pin form factor for I/O density requirements. Evaluate if the M8C architecture meets the computational needs of the target application.
Part Context
This part belongs to the PSoC 1 CY8C21xxx series, which combines a CPU with configurable analog and digital blocks. It represents a mixed-signal system-on-chip solution designed to reduce component count and design complexity. The series targets applications needing both digital control and analog signal processing capabilities.
Replacement Considerations
Check for direct substitutes within the CY8C21xxx series with different package options or speed grades. Verify cross-compatibility with other PSoC 1 variants offering similar memory sizes and peripheral sets.
