Application Specific Microcontrollers Procurement Notes

Verify that the ordering suffix 'IT' corresponds to the specific tape-and-reel packaging configuration required for automated assembly. Confirm compliance with RoHS directives and ensure the component meets the specified -40 °C to +85 °C operating temperature range for the target environment.

Application Specific Microcontrollers Selection Notes

Select this model when a dedicated capacitive touch controller with integrated processing is required. Ensure the design accommodates the 24-pin LQFP footprint and utilizes the available 28 GPIOs for system connectivity. Verify that the 32 KB memory capacity is sufficient for the application firmware.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress (now Infineon) PSoC 1 series, specifically the CY8CTST200 variant optimized for TrueTouch applications. It shares architectural similarities with the CY8CTMG20x series but focuses on capacitive sensing capabilities rather than general-purpose mixed-signal integration.
