Technical Details & Description

24 MHz Cortex-M0 with integrated analog and touch

It integrates CapSense capacitive-touch sensing, an LCD segment-drive controller, and a 12-bit SAR ADC (8-channel) plus two current DACs.

CapSense and LCD drive shrink the BOM

The integrated CapSense block replaces a dedicated touch-controller IC and its associated passives, saving about 15–20 mm² of board area in a typical four-button design. The LCD drive supports direct segment-glass connection without an external driver chip, cutting component count and assembly cost. Both peripherals run from the same 1.71 V to 5.5 V rail, simplifying power distribution.

Frequently asked questions

What is the difference between CY8C4124PVI-442 and CY8C4124PVI-442T?

Both share the same 28-SSOP package, 24 MHz Cortex-M0 core, 16 KB Flash, 4 KB SRAM, and peripheral set. The -442T suffix indicates the reeled shipping format for automated pick-and-place assembly lines.

Is CY8C4124PVI-442T lead-free?

Yes, it is ROHS3 Compliant, meaning it meets the EU RoHS directive for lead-free and restricted-substance limits.
