CY8C24423A-24SXI

Overview

The CY8C24423A-24SXI is an 8-bit Programmable System-on-Chip (PSoC) microcontroller from the CY8C24x23A family. It features an M8C processor core operating at up to 24 MHz, 4 KB of Flash program memory, and 256 bytes of SRAM data storage. The device includes four digital PSoC blocks and six analog PSoC blocks, supporting configurable peripherals such as ADCs, DACs, timers, and communication interfaces. It operates within a voltage range of 2.4 V to 5.25 V and supports an industrial temperature range of –40 °C to +85 °C.

Feature Summary

• Configurable analog and digital system resources allow custom peripheral creation
• Integrated M8C processor with Harvard architecture for efficient code execution
• Flexible GPIO configuration with multiple drive modes and interrupt capabilities
• On-chip clock generation including internal oscillators and PLL support

Applications

• Industrial control systems
• Consumer electronics
• Embedded sensor interfaces
• Battery-powered devices requiring low power operation

Procurement Notes

Verify the specific ordering suffix 'SXI' against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and development tools like PSoC Designer. Check for any end-of-life notices or recommended replacements from Infineon Technologies.

Selection Notes

Select this component when a mix of analog and digital programmability is required in a small footprint. Consider the CY8C24x23A family for designs needing configurable I/O and mixed-signal processing without external discrete components. Evaluate the 24 MHz performance against application timing requirements.

Part Context

This part belongs to the Cypress Semiconductor (now Infineon) PSoC 1 family, specifically the CY8C24x23A series. These devices are designed to replace multiple fixed-function ICs by integrating programmable logic, analog blocks, and a CPU on a single chip, reducing bill of materials and board space.

Replacement Considerations

Check for direct pin-compatible upgrades within the CY8C24x23A family. Verify if newer PSoC generations offer backward compatibility or require firmware adaptation.
