Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '00PVXI' against official Cypress documentation to confirm package type (SSOP-56) and lead-free status. Ensure compatibility with PSoC Designer development tools for configuration. Check for current availability through authorized distributors as manufacturing status may vary.

Application Specific Microcontrollers Selection Notes

Select this component for single-touch applications requiring up to 24 sensor inputs. Consider the 32-pin QFN version if space is limited, or the 56-pin SSOP for debugging features. Evaluate power requirements against the 2.7V to 5.25V operating range and industrial temperature specifications (-40°C to +85°C).

Application Specific Microcontrollers Part Context

The CY8CTST110 belongs to the TrueTouch family of single-touch controllers. It is part of the PSoC (Programmable System-on-Chip) architecture, allowing configurable analog and digital resources. Related models include CY8CTST120 for larger screens and CY8CTMG series for multi-touch gesture support.

Application Specific Microcontrollers Replacement Considerations

Direct substitutes within the same family include CY8CTST120 for larger display support. For multi-touch capabilities, consider CY8CTMG110 or CY8CTMA120. Verify pinout and memory size compatibility when replacing.
