The 25-WLCSP package (2.02 x 1.93 mm) is the smallest in the PSoC 4 family. 16 KB Flash and 2 KB SRAM suit a single-threaded control loop with moderate code size — a capacitive touch button panel with LED feedback, a basic sensor hub, or a simple motor/valve controller. ## Industrial temperature grade and environment The 25-WLCSP package is a direct-chip-attach footprint — no leads, no exposed pad — so board-level reliability depends on the PCB's solder-joint geometry and underfill choice if the assembly sees thermal cycling or vibration. For a production BOM, this part carries zero obsolescence risk through at least the next several years. If you need a second-source or a drop-in alternate, there is no direct pin-compatible second source from another manufacturer — the PSoC 4 architecture is proprietary to Infineon.","metaTitle":"Infineon CY8C4024FNI-S402T PSoC 4 MCU, 24 MHz, 16 KB Flash","metaDescription":"Infineon CY8C4024FNI-S402T 32-bit ARM Cortex-M0+ MCU, 24 MHz, 16 KB Flash, 2 KB RAM, CapSense, -40°C to 85°C, 25-WLCSP.

The CY8C4024FNI-S402T includes an integrated CapSense peripheral block, which is the same capacitive-sensing engine used across the PSoC 4 family. It supports buttons, sliders, proximity sensors, and matrix touchpads. The CapSense library is available in PSoC Creator and the ModusToolbox IDE."},{"question":"What are the direct alternatives or equivalents for CY8C4024FNI-S402T?","answer":"There is no pin-compatible second source from another manufacturer. Within the Infineon PSoC 4 family, the closest functional equivalent with more headroom is the CY8C4245LQI-483, which runs at 48 MHz, has 32 KB Flash, 4 KB RAM, and 8x12b ADC, but comes in a larger 34-pin QFN package. For a smaller code base, the CY8C4024FNI-S402T is the value-optimized entry point."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4024FNI-S402T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4024FNI-S402T when reusing this data.
