CY8C21434-24LFXI

Overview

The CY8C21434-24LFXI 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 SRAM. The device supports a maximum clock frequency of 24 MHz and operates within a voltage range of 2.4 V to 5.25 V. It includes one 10-bit Delta-Sigma ADC with a sampling rate of 5.9 ksps, 28 GPIO pins, and CapSense technology with one channel. The component is housed in a QFN-32 package and functions across a temperature range of -40 °C to 85 °C.

Feature Summary

Integrates CapSense technology for capacitive touch sensing capabilities
Includes a programmable Delta-Sigma analog-to-digital converter module
Supports embedded control applications through the M8C processor core

Applications

Embedded systems requiring real-time control and connectivity
Microcontroller-based consumer electronics interfaces
Capacitive touch sensing input devices

Procurement Notes

Verify the specific suffix LFXI against official datasheets to confirm package type and pinout compatibility. Confirm that the intended application aligns with the specified operating voltage and temperature ranges. Ensure design-in compliance with moisture sensitivity levels and reflow soldering profiles defined in the manufacturing documentation.

Selection Notes

Select this component when an 8-bit architecture with integrated analog peripherals and touch sensing is required. Consider the 24 MHz processing speed and available I/O count relative to system complexity. Evaluate the QFN-32 footprint constraints against PCB layout requirements and thermal management needs for the target environment.

Part Context

This part belongs to the CY8C21x34 series of the PSoC 1 family. It shares architectural similarities with variants like the CY8C21434-24LTXI, differing primarily in package configuration. The series targets cost-sensitive embedded applications needing mixed-signal processing and user interface integration.
