Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'A' indicates the temperature grade or revision level against the official datasheet. Confirm package integrity for the PVXI designation, which typically denotes a plastic small outline package. Check RoHS compliance status as per Cypress environmental declarations. Ensure supply chain authenticity through authorized distributors given potential obsolescence of legacy Cypress parts.

Application Specific Microcontrollers Selection Notes

Select this component when a dedicated single-touch controller with integrated processing is required. Compare pin compatibility with CY8CTST110 series if footprint constraints exist. Evaluate power consumption requirements against the standby and active modes specified in the electrical characteristics. Ensure the host system supports the I2C protocol speed supported by the device.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress TrueTouch family of capacitive touch controllers. It succeeded earlier resistive touch solutions and complements multi-touch variants like the CY8CTST120 series. The integration of the MCU reduces external component count compared to discrete sensor solutions. Cypress Semiconductor was acquired by Infineon Technologies, affecting long-term support documentation availability.

Application Specific Microcontrollers Replacement Considerations

Direct pin-to-pin replacements may include other CY8CTST200 variants with different suffixes indicating package or temperature variations. Cross-reference with Infineon's current portfolio for equivalent functionality if Cypress parts are discontinued. Verify firmware compatibility if migrating between different silicon revisions within the same family.
