Procurement Notes

Verify the specific suffix LTI-09 against the manufacturer's current product status, as Cypress components may have transitioned through obsolescence or lifecycle changes. Confirm RoHS compliance and lead times with authorized distributors, as availability for legacy Cypress parts can vary significantly. Ensure the package type matches the PCB footprint requirements during procurement planning.

Selection Notes

Select this component when a dedicated capacitive touch controller with integrated signal processing is required for multi-touch applications. Consider the pin count and package size relative to the available board space. Evaluate the power consumption specifications against battery-operated constraints if applicable. Verify compatibility with the intended sensor electrode layout and drive capabilities.

Part Context

This part belongs to the Cypress TrueTouch Standard family of capacitive touch controllers. These devices were widely used before Infineon Technologies acquired Cypress Semiconductor. The CY8CTMA series typically offers a balance of performance and integration level suitable for consumer electronics requiring responsive touch interfaces.

Replacement Considerations

Check for direct replacements from Infineon, which now holds the Cypress portfolio. Alternative controllers from other manufacturers may require significant firmware and hardware redesign due to differences in register maps and interface protocols.
