Product details

What this PSoC 4 MCU brings to a touch- or sensor-based design

The Infineon CY8C4024LQI-S413 is a PSoC 4 MCU from the CY8C4000S series, built around an ARM Cortex-M0+ core running at 24 MHz.

1.71 V supply — what it means for battery-powered boards

The supply voltage range starts at 1.71 V, which lets this MCU run directly from a single-cell Li-ion battery through most of its discharge curve without a boost converter. That simplifies the power rail and saves a few cents and a square millimeter of board area. The internal oscillator keeps the clock going without an external crystal, cutting two more components from the BOM. For a cost-sensitive touch panel or a wireless sensor node, that matters.

CapSense in hardware — no external touch controller needed

That means a single MCU handles both the application logic and the capacitive touch interface, eliminating a separate touch controller IC and its associated firmware overhead. For a panel with four to eight touch buttons, this consolidates the BOM and simplifies the supply chain.

Frequently asked questions

Does CY8C4024LQI-S413 support CapSense?

Yes, CapSense is listed among the integrated peripherals, along with LCD drive, LVD, POR, PWM, and WDT. No external touch controller is required.

What is the equivalent of CY8C4024LQI-S413?

The closest functional peer within the same PSoC 4 family is the CY8C4245LQI-483, which doubles the Flash to 32 KB and the core speed to 48 MHz, and adds a 12-bit ADC with eight channels plus two IDACs. It is a drop-in upgrade path for designs needing more memory or analog resolution, but it is not a pin-compatible second source — the package and pinout differ.
