CY8C24423A-24SXIT

Overview

The CY8C24423A-24SXIT is an 8-bit microcontroller from the Infineon PSoC 1 family, utilizing the M8C core. It features 4 KB of Flash program memory and 256 bytes of SRAM data storage. The device supports a maximum clock frequency of 24 MHz and includes six analog PSoC blocks capable of up to 14-bit ADC resolution. It provides 24 I/O pins in a SOIC-28 package, operating within a voltage range of 2.4 V to 5.25 V and an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Configurable analog and digital system-on-chip architecture allowing custom peripheral creation
• M8C processor with Harvard architecture supporting speeds up to 24 MHz
• Six rail-to-rail analog PSoC blocks for ADC, DAC, and amplifier functions
• Four digital PSoC blocks for timers, counters, PWMs, and communication interfaces

Applications

• Low-power embedded control systems
• Industrial sensor interfaces requiring programmable analog signal conditioning
• Battery-operated devices utilizing on-chip switch mode pump
• Applications needing flexible GPIO configurations with interrupt capabilities

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as Infineon Technologies, noting the original design by Cypress Semiconductor. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision *W for any silicon errata or electrical specification updates relevant to production.

Selection Notes

Select this model for designs requiring high configurability of analog and digital resources within a compact 28-pin package. The CY8C24423A-24SXIT is suitable where fixed-function peripherals are insufficient. Consider the 4 KB Flash limit for complex firmware applications. Evaluate the 2.4 V minimum supply voltage against your system power rails to ensure stable operation without external level shifting.

Part Context

This component belongs to the CY8C24x23A series of PSoC 1 devices. It is derived from the earlier CY8C24x23 family with optimizations for low power and lower voltage operation. The series shares the M8C core and similar block architectures but varies in memory sizes and pin counts across the portfolio.

Replacement Considerations

Direct substitutes include other members of the CY8C24x23A family such as CY8C24423A-24PVIT, which offers the same functionality in a SSOP-28 package. Verify pin compatibility and package dimensions before swapping between SOIC and SSOP variants.
