CY8C29466-24PVXAT

Overview

The CY8C29466-24PVXAT is an 8-bit microcontroller from Infineon Technologies, belonging to the PSoC 29x66 series. It features an M8C core with 32 kB of Flash program memory and 2 kB of RAM. The device operates at a maximum clock frequency of 24 MHz within a supply voltage range of 3 V to 5.25 V. It provides 24 I/O pins and includes four SPI interfaces, four UART interfaces, and one I2C interface. The component utilizes an SSOP-28 package and supports surface-mount installation.

Feature Summary

• Integrates configurable digital and analog peripherals within a programmable system-on-chip architecture
• Supports multiple communication protocols including SPI, UART, and I2C for versatile connectivity
• Combines an 8-bit microcontroller with embedded memory and mixed-signal capabilities

Applications

• Consumer electronics requiring mixed-signal processing
• Industrial equipment control systems
• Communication devices utilizing serial interfaces

Procurement Notes

Verify the specific suffix 'A' against official Infineon documentation to confirm tape-and-reel packaging status, as standard listings often indicate tube packaging for this series. Ensure the order quantity aligns with manufacturer minimums if reel packaging is confirmed. Cross-reference the datasheet revision date to validate current manufacturing status and RoHS compliance details before finalizing procurement.

Selection Notes

Select this component when a design requires a balance of moderate Flash capacity and extensive peripheral count in a compact SSOP-28 package. It is suitable for applications needing multiple serial interfaces without external logic. Compare against lower-memory variants like the CY8C27443 if code size permits, or higher-pin-count models if additional I/O is required.

Part Context

This part belongs to the PSoC 29x66 family, which offers a programmable mixed-signal array. These controllers integrate configurable analog blocks, digital peripherals, and an 8-bit CPU on a single chip. This architecture allows designers to customize hardware functions, reducing board space and component count compared to discrete solutions.

Replacement Considerations

Direct substitutes within the same package and pinout include other CY8C29x66 variants with different memory sizes, such as the CY8C29466-24PVXI. Verify electrical specifications and software compatibility when swapping between memory configurations.
