Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm end-of-life status or availability through authorized distributors, as component lifecycles may have changed since the original datasheet publication.

Application Specific Microcontrollers Selection Notes

Select this part for designs requiring simultaneous multi-finger tracking on displays up to 7.3 inches. Ensure the system design accommodates the 3V to 5.25V supply range and utilizes the available GPIOs for the required number of sensor inputs. Consider the internal oscillator accuracy if precise timing is critical for the touch application.

Application Specific Microcontrollers Part Context

This component belongs to the Cypress TrueTouch family of capacitive touchscreen controllers. It is part of the PSoC (Programmable System-on-Chip) architecture, which allows for configurable analog and digital resources. The device is designed to replace fixed-function touch controllers by offering programmable hardware blocks for customized signal processing.

Application Specific Microcontrollers Replacement Considerations

Check for updated revisions within the CY8CTMA120 series or newer TrueTouch models like the CY8CTMA1xx variants. Verify pin compatibility and software library support when migrating to alternative parts from Infineon or other manufacturers.
