Applications
- Consumer electronics requiring mixed-signal processing
- Industrial equipment control systems
- Communications interface modules
Procurement Notes
Verify the specific suffix 'SXIT' against official Infineon documentation to confirm package type and temperature grade, as datasheets often list 'PVXIT'. Ensure compatibility with PSoC Designer software versions. Confirm RoHS compliance status through the manufacturer's current product change notification or datasheet revision history before finalizing procurement specifications.
Selection Notes
Select this component when an 8-bit MCU with integrated analog peripherals is required. The CY8C27243 offers a balance of processing speed and mixed-signal functionality. Consider the 16 kB Flash size for application code requirements. Verify that the 20-pin SSOP package fits the board layout constraints. Compare against other CY8C27x43 variants if different pin counts or memory sizes are needed.
Part Context
This part belongs to the Infineon CY8C27x43 series of PSoC Mixed Signal Controllers. These devices combine an 8-bit CPU with programmable analog and digital blocks. The series targets applications needing flexibility in peripheral configuration. Other members in the family may vary in I/O count, memory size, or package options while sharing the same core architecture.
FAQ
What is the instruction set architecture of the CY8C27243?
The CY8C27243 utilizes a Harvard architecture instruction set optimized for the M8C processor core.
Does the CY8C27243 support CapSense technology?
Official datasheets for the CY8C27243 do not explicitly list CapSense support, unlike other models in the broader PSoC 1 family such as the CY8C21434.
