Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and feature set. Ensure compatibility with the target sensor size and interface requirements before procurement.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring four-finger tracking and stylus support. Verify that the system design accommodates the required digital and analog supply voltage ranges and utilizes either I2C or SPI interfaces.

Application Specific Microcontrollers Part Context

This part belongs to the CY8CTMA340 family of TrueTouch controllers. It shares core capabilities with other variants but is distinguished by its 36-pin QFN package and specific node count configuration.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include the CY8CTMA340-LQI-09, which offers identical hardware but lacks stylus support. Cross-family replacements require verification of pinout and software compatibility.
