CY8C24423A-24LFXIT

Overview

The Infineon CY8C24423A-24LFXIT is an 8-bit microcontroller from the PSoC family, featuring a 24 MHz M8C processor core. It integrates 4 KB of Flash program memory and 256 bytes of SRAM data storage within a 32-pin QFN package. The device supports an operating voltage range of 2.4 V to 5.25 V and includes up to 14-bit ADCs, 9-bit DACs, and programmable analog blocks. It offers 24 I/O pins with configurable drive modes and supports industrial temperature ranges.

Feature Summary

• Configurable mixed-signal architecture with six analog and four digital PSoC blocks for custom peripheral creation
• M8C processor core delivering high-speed performance at low power consumption levels
• Flexible GPIO configuration supporting multiple drive modes and interrupt capabilities on all pins
• Integrated system resources including switch mode pump, watchdog timer, and precision voltage reference

Applications

• Industrial control systems requiring mixed-signal processing
• Portable battery-powered devices utilizing the switch mode pump
• Data acquisition systems using programmable analog-to-digital converters
• Embedded sensor interfaces with configurable digital communication protocols

Procurement Notes

Verify the specific suffix LFXIT against official Infineon documentation to confirm the 32-pin QFN package and lead-free status. Ensure the revision level matches the required design specifications. Confirm availability through authorized distributors as part numbers may have lifecycle changes. Cross-reference the datasheet document number 38-12028 for accurate electrical characteristics.

Selection Notes

Select this component when a single-chip solution replaces multiple discrete MCU and analog components. The PSoC architecture allows hardware customization without changing silicon. Consider the 24 MHz clock speed and 4 KB Flash size for application complexity. Evaluate the available analog blocks for signal conditioning needs before choosing alternative fixed-function MCUs.

Part Context

This device belongs to the CY8C24x23A series of Programmable System-on-Chips. It is derived from the CY8C24x23 family with enhancements for low power and low voltage operation. The series is designed to reduce external component counts by integrating configurable analog and digital logic on a single die.

Replacement Considerations

Check for CY8C24423A variants with different packages such as SSOP or PDIP if pin compatibility differs. Verify functional equivalence with CY8C24223A for lower pin count requirements. Consult official discontinuation notices for legacy replacements.
