The operating temperature range of -40°C to 85°C qualifies it for outdoor telecom cabinets, factory-floor sensors, and engine-bay-adjacent modules. ## 24 MHz core — where it fits and where it doesn't The 24 MHz clock is adequate for real-time control loops, capacitive touch scanning, and low-speed data logging. It is not a part for high-rate signal processing or video — the sibling CY8C4245LQI-483 runs at 48 MHz and offers 8x12-bit SAR ADC channels for applications needing faster sampling or more analog front-end resolution. ## CapSense and LCD drive — BOM consolidation The integrated CapSense block eliminates a dedicated touch controller IC and its associated PCB routing. The LCD drive supports segment displays without an external driver chip. For a control panel with a small segment LCD and capacitive buttons, this MCU covers both with one firmware image. ## Lifecycle and supply posture The CY8C4024LQI-S412T carries an Active lifecycle status from Infineon — no last-time-buy or obsolescence notice on record. It is ROHS3 compliant. For production builds, the part is available in Tape & Reel or Cut Tape options, and we source it through multiple distribution channels.","metaTitle":"Infineon CY8C4024LQI-S412T PSOC 4 MCU, 24 MHz, 16 KB Flash","metaDescription":"Infineon PSOC 4 CY8C4000S ARM Cortex-M0+ MCU, 24 MHz, 16 KB Flash, 2K x 8 RAM, CapSense, -40°C to 85°C, 32-UFQFN.
