Application Specific Microcontrollers Procurement Notes

This component is designated as an End-of-Life (EOL) product by Infineon Technologies. Verification of current availability should be conducted through authorized distributors or secondary market suppliers. Buyers must confirm lead times and lot dates carefully, as stock is limited and subject to change without notice.

Application Specific Microcontrollers Selection Notes

Select this part when a dedicated CapSense controller with integrated M8C processing is required. Ensure the 16 kB flash capacity meets application firmware needs. Verify that the 16-pin QFN package fits the PCB layout constraints. Consider the operating temperature range (-40 °C to +85 °C) against environmental requirements.

Application Specific Microcontrollers Part Context

The CY8C20246AS-24LKXI belongs to the CY8C20xx6A family of PSoC 1 devices. This series is designed to replace multiple traditional MCU components with a single programmable chip. It combines analog and digital configurable blocks with a fast CPU, making it suitable for complex embedded control tasks involving user interface elements.

Application Specific Microcontrollers Replacement Considerations

As an EOL product, direct replacements may not exist within the same family. Review the CY8C20336H or CY8C20446H datasheets for pin-compatible or functionally similar alternatives, noting differences in flash size and package options.
