CY8C29666-24PVXIT

Overview

The CY8C29666-24PVXIT is an 8-bit microcontroller from the Infineon PSoC 1 family, utilizing the M8C core. It features 32 KB of Flash program storage and 2 KB of SRAM data memory. The device supports a maximum clock frequency of 24 MHz and operates within a voltage range of 3.0 V to 5.25 V. It includes 12 analog PSoC blocks and 16 digital PSoC blocks for configurable peripherals. The component is housed in a 48-pin QFN package.

Feature Summary

• Configurable mixed-signal architecture with programmable analog and digital blocks
• High-performance 8-bit M8C processor with Harvard architecture
• Flexible GPIO configuration with multiple drive modes and interrupt capabilities
• Integrated system resources including switch-mode pump and low-voltage detection

Applications

• Consumer electronics requiring mixed-signal processing
• Industrial equipment control systems
• Automotive embedded applications
• Communication devices with serial interface requirements

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and temperature grades. Confirm that the 48-pin QFN package dimensions align with your PCB footprint design. Check for any recent revisions to the part number or associated errata documents before finalizing procurement specifications.

Selection Notes

Select this component when a design requires extensive analog and digital configurability on a single chip. The high count of PSoC blocks allows for custom peripheral creation, reducing external component count. Ensure the application fits within the 32 KB Flash and 2 KB SRAM limits while supporting the 24 MHz operational speed.

Part Context

This part belongs to the CY8C29x66 series within the broader PSoC 1 portfolio. It represents a high-resource variant designed for complex applications needing significant programmable logic. The series is characterized by its ability to replace multiple discrete MCU and analog components with a single integrated solution.

Replacement Considerations

Consult official documentation for direct pin-to-pin substitutes within the CY8C29x66 family, such as the CY8C29466 or CY8C29566, noting differences in I/O counts and block availability.
