Product details

What this PSOC 4 MCU delivers for a BOM line

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.

It is ROHS3 compliant.

Frequently asked questions

What is the closest functional second-source for CY8C4024LQI-S412T?

The CY8C4245LQI-483 is a pin-compatible PSOC 4 variant with a 48 MHz Cortex-M0 core, 8x12-bit SAR ADC, and 34 I/O. It offers higher performance and more analog channels, but verify the memory size and package compatibility for your specific layout.
