CY8C27143-24PXI

Overview

The CY8C27143-24PXI is an 8-bit microcontroller from Infineon Technologies, belonging to the PSoC mixed-signal array family. It integrates an M8C core with 16 kB of Flash program memory and 512 bytes of SRAM data RAM. The device supports a maximum clock frequency of 24 MHz and operates within a supply voltage range of 2.4 V to 5.25 V. It features a 10-bit ADC, 28 I/O pins, and interfaces including SPI, UART, and I2C. The component is housed in a QFN-32 package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates configurable digital and analog peripherals within a single system-on-chip architecture
• Includes a 10-bit Analog-to-Digital Converter for signal processing applications
• Supports multiple communication protocols such as SPI, UART, and I2C

Applications

• Consumer electronics devices requiring mixed-signal control
• Industrial equipment monitoring and control systems
• Computational modules in embedded systems
• Communication interface hardware

Procurement Notes

Verify the specific suffix 'PXI' against official Infineon documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the QFN-32 configuration. Cross-reference the exact part number with current datasheets to validate manufacturing status and availability before finalizing procurement plans.

Selection Notes

Select this component when an 8-bit MCU with integrated analog capabilities is required. The 16 kB Flash and 512 B RAM provide sufficient resources for moderate complexity logic. The 24 MHz speed and mixed-signal features make it suitable for applications needing both digital processing and analog input handling without external components.

Part Context

This model is part of the CY8C27x43 series, representing Infineon's PSoC technology. These controllers combine an 8-bit CPU with programmable analog blocks and digital interconnects. The series targets designs aiming to reduce board space and component count by integrating peripheral functions directly onto the silicon die.

Replacement Considerations

Check for CY8C27143 variants with different suffixes indicating alternate packages or temperature ranges. Verify pinout compatibility if substituting with other members of the CY8C27x43 family.
