CY8C21323-24LFXIT

Overview

The CY8C21323-24LFXIT is an 8-bit microcontroller from the PSoC family, featuring an M8C processor with speeds up to 24 MHz. It includes 4 KB of Flash program storage and 256 bytes of SRAM data storage. The device operates within a voltage range of 2.4 V to 5.25 V and supports industrial temperatures from -40 °C to +85 °C. It provides up to 16 GPIO pins and integrates four analog Type E PSoC blocks for comparators and 10-bit ADCs, alongside digital blocks for timers, counters, PWMs, UART, SPI, and I2C interfaces.

Feature Summary

• Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
• M8C Harvard-architecture processor supporting speeds up to 24 MHz
• Integrated switch mode pump enabling operation from single battery cells
• Flexible on-chip memory with in-system serial programming capabilities

Applications

• Consumer electronics requiring low component count
• Industrial equipment control systems
• Automotive embedded applications
• Battery-powered devices utilizing switch mode pump functionality

Procurement Notes

Verify the specific ordering suffix LFXIT against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with PSoC Designer development tools. Confirm RoHS compliance status through current datasheets. Check for any silicon errata affecting frequency tolerance at extreme temperatures before finalizing procurement specifications.

Selection Notes

Select this component when design flexibility is required over fixed-function MCUs. The PSoC architecture allows hardware reconfiguration without changing components. Consider the 24 MHz processing speed and available I/O count for system requirements. Evaluate the need for analog peripherals like the 10-bit ADC or comparators which are integrated into the programmable blocks.

Part Context

This part belongs to the CY8C21x23 series of PSoC Programmable System-on-Chips. These devices are designed to replace multiple traditional MCU-based system components with a single chip. The series combines an 8-bit CPU with configurable analog and digital blocks, offering a complete system-level solution for mixed-signal applications.

Replacement Considerations

Consult official Infineon substitution guides for verified equivalents. Generic cross-references may not support the unique PSoC configurability. Verify pinout and electrical characteristics match if considering alternative packages within the same family.
