CY8C20334-12LKXI

Overview

The CY8C20334-12LKXI is an 8-bit microcontroller from Infineon Technologies, featuring the M8C core. It integrates 8KB of Flash memory and operates at a maximum frequency of 12MHz. The device provides 20 general-purpose I/O pins and supports connectivity via I2C and SPI interfaces. It includes hardware peripherals such as Low Voltage Detect (LVD), Power-On Reset (POR), and a Watchdog Timer (WDT). The component is housed in a 24-UFQFN package with an exposed pad and functions within a voltage range of 1.71V to 5.5V across an industrial temperature range.

Feature Summary

• Integrates an 8-bit M8C processor core for efficient code execution.
• Includes essential system management peripherals like LVD, POR, and WDT.
• Supports standard serial communication protocols including I2C and SPI.

Applications

• General-purpose embedded control systems
• Battery-powered devices requiring low voltage operation
• Industrial monitoring applications utilizing watchdog protection

Procurement Notes

Verify the specific suffix 'LKXI' against official Infineon documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with PSoC Designer software versions. Confirm that the 19-week standard lead time aligns with project schedules. Validate RoHS compliance status through current datasheets rather than distributor summaries.

Selection Notes

Select this component when an 8-bit architecture suffices for control tasks. The 12MHz speed limit defines performance boundaries compared to higher-frequency variants. Consider the 24-pin QFN footprint for PCB layout constraints. Verify that the 8KB Flash capacity meets firmware storage requirements before finalizing the design.

Part Context

This part belongs to the Cypress PSoC 2 family, now under Infineon. It utilizes the M8C core distinct from ARM-based PSoC models. The series emphasizes low power consumption and integrated analog-digital capabilities. This specific model focuses on digital I/O and basic peripheral integration without advanced capacitive sensing features found in other SKUs.

Replacement Considerations

Direct substitutes include CY8C20334-12LQXI which shares identical electrical characteristics but differs in package configuration. Cross-reference pinouts carefully when swapping between UFQFN and LQFP packages. No functional equivalent exists outside the PSoC 2 family due to unique M8C architecture dependencies.
