Overview
The CY8C20424-12LKXIT is an 8-bit microcontroller from the Infineon PSoC 1 family, utilizing the M8C core. It features 8 KB of Flash program memory and 512 bytes of data RAM. The device supports a maximum clock frequency of 12 MHz and operates within a voltage range of 2.4 V to 5.25 V. It provides up to 28 I/O pins and includes CapSense technology for capacitive sensing applications. The component is housed in a QFN-32 package and functions without an integrated ADC.
Feature Summary
- Integrates CapSense technology for capacitive touch sensing solutions
- Features SmartSense automatic tuning algorithm for ease of use
- Supports low power operation with wide voltage range
Applications
- Capacitive touch interface controllers
- Low power embedded control systems
- Consumer electronics input devices
Procurement Notes
Verify the specific suffix LKXIT against official Infineon documentation to confirm package type and tape/reel configuration. Ensure compatibility with PSoC Designer software versions supporting the CY8C20xx series. Check RoHS compliance status and moisture sensitivity levels prior to assembly planning.
Selection Notes
Select this component when a balance of moderate processing speed and integrated capacitive sensing is required. The 12 MHz limit suits applications not demanding high-frequency digital signal processing. Consider the 28 I/O count for system integration needs and verify that the absence of an on-chip ADC meets analog signal requirements.
Part Context
This part belongs to the PSoC 1 CY8C20xx6A series, designed for mid-range CapSense applications. It combines programmable logic with fixed-function peripherals on a single chip. The series emphasizes rapid prototyping and market entry through flexible hardware configuration capabilities.
Replacement Considerations
Check for CY8C20424 variants with different suffixes for package or temperature changes. Cross-reference with CY8C20xxx family members for pin-compatible upgrades if higher performance is needed.
