CY8C202244-12LKXI

Overview

The CY8C202244-12LKXI is a PSoC 2 programmable system-on-chip microcontroller from Infineon Technologies. It features an M8C 8-bit CPU with a maximum operating frequency of 24 MHz. The device includes one 10-bit Delta-Sigma ADC module and supports up to 12 CapSense channels using CSX technology. It provides 13 GPIO pins and integrates one I2C interface and one SW SPI interface. The unit operates within a voltage range of 1.71 V to 5.5 V and functions in temperatures from -40 °C to 85 °C, housed in a 16-QFN (3x3) package.

Feature Summary

Integrates CapSense Plus touch sensing technology with CSX capability for intuitive human-machine interfaces.
Features a reconfigurable analog and digital peripheral array allowing custom hardware acceleration.
Combines an 8-bit M8C processor with flexible programmable interconnects for mixed-signal applications.

Applications

Touch-sensitive control panels and user interfaces
Battery-powered portable consumer electronics
Smart home automation controllers

Procurement Notes

Verify the specific suffix '12LKXI' against official Infineon documentation to confirm pinout, package dimensions, and temperature grade. Ensure compatibility with the PSoC Designer development environment. Confirm RoHS compliance status through current manufacturer certificates before procurement.

Selection Notes

Select this component when a low-pin-count MCU requires integrated capacitive touch sensing without external processors. The 16-QFN package suits space-constrained designs. Verify that the 24 MHz clock speed and 10-bit ADC resolution meet application requirements compared to higher-performance PSoC families.

Part Context

This part belongs to the PSoC 2 family, designed for cost-sensitive embedded applications requiring analog-digital integration. It utilizes the M8C core architecture, distinguishing it from later ARM-based PSoC generations. The series emphasizes ease of design through graphical configuration tools.

Replacement Considerations

Direct substitutes require matching the M8C architecture and 16-QFN package. Review PSoC 2 datasheets for pin-compatible variants with differing memory or peripheral counts. Cross-reference with PSoC 3 or 4 only if architectural migration is acceptable.
