Microcontrollers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the temperature grade (Grade-A, -S, or -E) matches the application's environmental requirements. Ensure the QFN package type aligns with PCB layout constraints. Cross-reference the full part number against official Infineon documentation to confirm availability and revision status before finalizing procurement plans.

Microcontrollers Selection Notes

Select this component for designs requiring robust automotive compliance combined with flexible analog-digital integration. The PSoC™ 4100S Plus architecture allows customization of peripherals, reducing external component count. Consider the available GPIO count and memory size relative to firmware complexity. Evaluate the power consumption profiles across Active, Sleep, and Deep Sleep modes to ensure they meet system energy efficiency targets.

Microcontrollers Part Context

This device is part of the broader PSoC™ 4 portfolio, specifically the 4100S Plus series designed for automotive applications. It shares architectural similarities with other PSoC™ 4 devices but offers enhanced analog performance and automotive certification. The platform supports upward compatibility with existing PSoC™ 4 designs, facilitating migration and reuse of software libraries and hardware schematics across different project generations.

Microcontrollers Replacement Considerations

Check for direct pin-to-pin replacements within the same PSoC™ 4100S Plus family that may offer different memory sizes or package options. Verify if alternative suffixes denote different temperature grades or packaging styles rather than functional changes. Consult the official product selector guide to identify compatible parts with similar peripheral configurations and electrical characteristics.
