Application Specific Microcontrollers Procurement Notes

Verify the specific suffix '56LTXI' against official Cypress documentation to confirm package type and lead-free status. Ensure compatibility with existing firmware if replacing older variants. Check for end-of-life notices from Infineon Technologies, which acquired Cypress Semiconductor.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring integrated touch sensing and MCU functionality in a single-chip solution. Consider the SSOP-56 footprint constraints during PCB layout. Verify that the 1.71V-5.5V supply range matches the system power architecture.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress TrueTouch family of capacitive touch controllers. It is distinct from multi-touch variants like the CY8CTMA series. The manufacturer has transitioned under Infineon Technologies, affecting long-term support channels.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements may include other CY8CTST120 variants with different suffixes (e.g., -56LFXI) if package differences are acceptable. Cross-reference with Infineon's current portfolio for updated equivalents.
