CY8C24423A-12PVXE

Overview

The Infineon CY8C24423A-12PVXE is an automotive-grade Programmable System-on-Chip (PSoC) featuring the M8C processor core operating at speeds up to 12 MHz. It integrates 4 KB of Flash program storage and 256 bytes of SRAM data memory within a 28-pin SSOP package. The device supports an operating voltage range of 4.75V to 5.25V and functions reliably in extended temperature environments from -40°C to +125°C. Key peripherals include six analog PSoC blocks for signal processing and four digital PSoC blocks for logic control.

Feature Summary

• Automotive qualification compliant with AEC standards for reliability
• Configurable analog system with rail-to-rail blocks supporting ADCs, DACs, and amplifiers
• Flexible digital architecture allowing custom peripheral creation via global interconnects
• Integrated precision clocking with internal oscillators and PLL support

Applications

• Automotive sensor interfaces requiring high-speed analog-to-digital conversion
• Engine control units utilizing programmable pulse-width modulation
• Body electronics systems needing configurable general-purpose I/O
• Industrial monitoring applications operating in extreme temperature ranges

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets current automotive quality standards relevant to your supply chain requirements. Ensure compatibility with existing development tools such as PSoC Designer for firmware implementation.

Selection Notes

Select this model when fixed-function microcontrollers lack the necessary analog flexibility or pin count. The PSoC architecture allows hardware reconfiguration, reducing bill-of-materials complexity. Consider the 12 MHz speed limit if higher processing throughput is required for complex algorithms.

Part Context

This component belongs to the CY8C24x23A family of PSoC devices designed for mixed-signal applications. It combines an 8-bit CPU with programmable analog and digital blocks. The family targets cost-sensitive designs that require significant customization without increasing chip count.

Replacement Considerations

Direct substitutes within the same automotive extended temperature series include the CY8C24223A variant. Verify pinout compatibility and peripheral configuration equivalence before swapping components in existing designs.
