Procurement Notes

Verify the specific ordering suffix LDX2IT to confirm the tape and reel packaging configuration, as this affects handling and assembly processes. Ensure the selected variant matches the required voltage and temperature specifications for the target application environment. Cross-reference the datasheet for exact pinout assignments and electrical characteristics before integration into the design.

Selection Notes

Select this component when a single-chip solution combining a microcontroller with capacitive touch sensing is required. It is suitable for applications needing multiple touch inputs without external touch controllers. Consider the 16-pin QFN footprint for space-constrained designs. Evaluate the I2C interface compatibility with the host system for data communication requirements.

Part Context

This part belongs to the CY8C201xx series of PSoC 1 devices from Infineon. These are programmable system-on-chip solutions designed to reduce component count and board space.
