CY8C24423A-12PVXET

Overview

The CY8C24423A-12PVXET is an automotive-grade PSoC microcontroller 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 4.75 V to 5.25 V and functions across an extended temperature range from -40°C to +125°C. It includes six analog PSoC blocks for ADCs, DACs, and amplifiers, alongside four digital PSoC blocks for timers, counters, and communication interfaces.

Feature Summary

• Automotive qualification compliant with AEC standards for reliability in vehicle environments
• Configurable analog system with six blocks supporting high-resolution ADCs and precision comparators
• Flexible digital architecture allowing custom peripheral creation via programmable interconnects
• Integrated supervisory circuits including low voltage detection and power-on reset

Applications

• Automotive body control modules requiring robust I/O handling
• Sensor interface systems utilizing programmable analog signal conditioning
• Industrial controllers operating in extended temperature conditions
• Battery management subsystems leveraging precise voltage monitoring

Procurement Notes

Verify that the specific suffix PVXET corresponds to the required packaging and tape-and-reel configuration for automated assembly lines. Confirm that the automotive grade designation aligns with your specific quality management system requirements. Ensure compatibility with the 4.75V to 5.25V supply rails present in your target circuit design before finalizing procurement orders.

Selection Notes

Select this component when fixed-function peripherals are insufficient for complex signal processing tasks. The PSoC architecture allows runtime reconfiguration of analog and digital blocks, reducing bill-of-materials count. Consider this part for designs needing high noise immunity and precise analog measurements within a single-chip solution. Evaluate the 28-pin SSOP footprint against available PCB space constraints.

Part Context

This device belongs to the CY8C24x23A family of Programmable System-on-Chips designed for cost-sensitive applications. It combines a Harvard architecture CPU with configurable logic blocks, enabling designers to replace multiple discrete components. The family emphasizes flexibility through software-configurable hardware resources rather than fixed peripheral sets.

Replacement Considerations

Check for CY8C24423A variants with different suffixes if alternative packaging or temperature grades are needed. Verify pinout compatibility when substituting with other members of the CY8C24x23A series.
