For a capacitive touch panel scanning 8 channels with the on-chip SAR ADC, that clock rate gives sub-millisecond scan times — fast enough for responsive button/slider interfaces. It also handles UART polling and PWM generation without stalling the touch firmware. If your application needs more compute (e.g., audio processing or complex math), the PSoC 4 family offers 48 MHz variants like the CY8C4245LQI-483, but they come with a different package and a narrower temperature range of -40°C to 85°C. ## Active lifecycle — no LTB risk on this line The CY8C4124LQQ-443 carries an Active product status with ROHS3 compliance. For a BOM line that needs a stable, long-term supply, this part does not introduce obsolescence risk. ## Industrial temperature range — outdoor and motor-drive capable Rated for -40°C to 105°C, this MCU fits applications that see thermal cycling: outdoor telecom enclosures, factory automation panels near motor drives, and under-hood automotive modules (though it lacks AEC-Q100 certification). The 40-QFN with exposed pad helps conduct heat to the PCB ground plane, keeping the die within limits even when driving the on-chip PWM outputs at full duty cycle.","metaTitle":"Infineon CY8C4124LQQ-443 PSoC 4 MCU, ARM Cortex-M0, 24 MHz","metaDescription":"Infineon CY8C4124LQQ-443 PSoC 4 MCU: 32-bit ARM Cortex-M0 at 24 MHz, 16 KB Flash, 4K x 8 RAM, CapSense, -40 to 105°C.
